The theme labor competition of the Sichuan East Gas Pipeline Second Line Project of the Pipeline Bureau, titled "100 Days of Fighting and Striving for Excellence in Sichuan Second Line", showcased many innovative aspects: achieving the goals of "Four First Class", "Double Innovation", "Six Competitions", etc., a group of typical representatives emerged, "competition" produced a "new engine" for mountain construction, "competition" produced an "acceleration" for project construction, and "competition" produced a "new style" for pipeline teams. Labor competition is led by the Party and the working class An important carrier for grasping production and promoting development Inspiring the labor passion of all employees in the enterprise to strive for excellence Since it's a 'competition' We need to 'compete' to determine our level and 'compete' to determine the outcome that What are the outstanding features of the Sichuan Second Line project? The project is the most fundamental profit unit of the pipeline bureau and also the forefront of value creation. Unlike the previous single pursuit of progress indicators, the Sichuan Second Line project positions the goal of labor competition as "management". Through comprehensive budget management, the project department locks in the total cost of each unit, conducts cost analysis on a weekly and monthly basis for different terrains and seasons, scientifically analyzes process efficiency, and ensures controllable costs in each link. For example, Heat Shrinkable Sleeves covered 3LPE Heat Shrink Sleeves,2PE Heat Shrink Tape,3LPP Wrap Around Sleeve HDD Heat Shrink Wrap Sleeves,Shrinkable Tape Closure Patch, By strengthening the "two-way" control of comprehensive budget and single process full cost, deepening internal contracting of the unit, solidifying all factors to reduce costs and increase efficiency, and gradually implementing the "benefit oriented management" approach, the competition results will be continuously transformed into benefit oriented achievements. This is an effective exploration of focusing on winning the "four major battles", and also reflects a gratifying shift in the thinking of project managers from "managing projects" to "managing projects". Not satisfied with the current situation, not afraid of challenges, innovation is everywhere in the entire process of the Sichuan Second Line project from winning the bid to advancing implementation. Unlike the traditional competition method of simply extending working hours and increasing resource investment, the Sichuan Second Line project positions the competition point of labor competition as "innovation". By investing in new specialized mountain equipment (flexible internal welding machines, short axis beveling machines, etc.) and adopting new process techniques (fully automatic argon arc external root welding process, fully automatic welding hot bending elbow straight pipe process, etc.), the efficiency and industry threshold are fundamentally improved. This self breakthrough accurately outlines the enterprise's attitude towards facing the severe industry situation.

3PE anti-corrosion steel pipe structure 3PE anti-corrosion steel pipes usually consist of three layers: The first layer of epoxy powder (FBE>100um); The second layer of adhesive (AD) is 170-250um; The third layer of polyethylene is 2.5-3.7mm; In practice, these three materials are mixed and integrated together, and after processing, they are firmly combined with the steel pipe to form an excellent anti-corrosion coating. Generally speaking, there are two processing methods: winding type and circular mold covering type. 1. 3PE anti-corrosion steel pipes have high sealing performance, and long-term operation can greatly save energy, reduce costs, and protect the environment. 2. Strong corrosion resistance, simple and fast structure, with a service life of 30-50 years. 3. At low temperatures, PE has good corrosion resistance and impact resistance, with low water absorption. 4. At the same time, it has high epoxy strength, low polyethylene water absorption, and good flexibility of hot melt adhesive. Has high anti-corrosion reliability. The characteristics of this anti-corrosion method are simple production process, good anti-corrosion effect, and low price. It is a recognized anti-corrosion method for pipeline manufacturing in the industry. Three layers of polyethylene (3PE) steel pipes are used for anti-corrosion in oil and natural gas, and two layers of polyethylene (2PE) steel pipes are used for anti-corrosion. The standard is SY/T0413-2002; DIN30670. Scope of use of 3PE anti-corrosion steel pipes 1. It is applicable to underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas discharge, fire spray and other pipe networks in thermal power plants. Handle waste residue and return water transportation pipelines. 2. Suitable for water supply pipelines in sprinkler systems, suitable for cable coverage in power, communication, highways, and other fields. 3. Suitable for high-rise building water supply, heating network, tap water engineering, gas transportation, buried water transportation and other pipelines. Process pipelines used for transporting corrosive media in petroleum pipelines, chemical drugs, and printing and dyeing industries. 4. Sewage treatment and discharge pipes, sewage pipes, and biological tank anti-corrosion engineering. Agricultural irrigation pipes, deep well pipes, drainage pipes, and other pipe networks. 2PE anti-corrosion steel pipe: The two anti-corrosion structures of the pipeline - the first layer of adhesive (AD) and the second layer of polyethylene (PE) - are integrated together, with each layer having the same thickness as the three layers of PE. 3PE anti-corrosion (three-layer polyethylene), also known as extruded polyethylene structure protective layer. The 3PE anti-corrosion technology combines the excellent performance of extruded polyethylene and epoxy coatings, combining the interface characteristics of epoxy coatings with the mechanical protection characteristics of polyethylene coatings, thereby significantly improving their respective performance. Its characteristics include high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, and adaptability to cold regions. Therefore, a 3PE anti-corrosion layer is an ideal external protective coating for buried pipelines. From the above content, it can be seen that the difference between 2PE and 3PE is that 3PE has an additional layer of epoxy powder for anti-corrosion, and epoxy powder has good mechanical properties, corrosion resistance, and strong resistance to cathodic stripping. Although it has advantages such as strict surface treatment, poor weather resistance, and high water absorption rate, it is suitable for buried pipelines and submarine pipelines. The thickness of the coating layer is only 0.3-0.5 millimeters, and the service life can reach 40-50 years. Whether it is 3LPE anti-corrosion pipe or 2LPE anti-corrosion pipe, we have corresponding Heat Shrinkable Sleeves, 3LPE Heat Shrink Sleeves, 2PE Heat Shrink Tape, and we also have 3LPP Wrap Around Sleeves, HDD Heat Shrink Wrap Sleeves, and Shrinkable Tape Closure Patches to meet various anti-corrosion requirements and meet various customer needs.

When constructing large-scale projects, in addition to the purchased heat shrink materials, repair patches will also be added. As we all known,Repair patch is a product used for repairing and repairing the anti-corrosion outer layer of 3LPE pipelines coating. During the construction process of heat shrink sleeves or the transportation of pipes, it is inevitable that there may be some surface wound problems such as scratches and small cracks,When such a small wound occurs, if the main material is replaced, it will waste time and labor, and it will also damage the original anti-corrosion structure, affecting the overall anti-corrosion effect. Polyethylene repair patches and repair rods, like magical pipeline bandages, timely and effectively solve this problem. Pipe Repair Materia lcovered Repair Patch,Melt Stick,Mastic Tape. The specific introduction is as follows: Repair patch is a radiation cross-linked repair designed and developed specifically for repairing polyethylene anti-corrosion coatings on steel pipelines. Composition: The repair patch is composed of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive, which is heated during construction to repair the damage The parts are tightly bonded and integrated with the external anti-corrosion layer, evenly covering the surface of the pipeline, forming a continuous and tight anti-corrosion system. Features: sealed, waterproof, anti-aging, can resist soil stress, hydrostatic pressure, and cathodic stripping. Antichemical Corrosion and mold erosion provide long-term effective protection. Usage: Mainly used for polyethylene two-layer and three-layer anti-corrosion of pipelines. The polyethylene outer anti-corrosion layer is used for transportation, inspection, and construction Repair of damage caused in engineering, such as small area damage of less than 100mm square caused by point or line scratches in local areas Characteristics Specially used for repairing and repairing anti-corrosion joints of steel pipelines; There are two forms of patching (patching without heat shrinkage) and patching tape. The damaged area of the jacket is less than 100 square millimeters When going down, use a patch to repair the damage. When the damage area of the jacket is over 100 square millimeters, or the axial and radial damage is severe, Repairing injuries should use patching tape; Good mechanical properties such as wear resistance, impact resistance, and penetration resistance. Strong adaptability to the environment. Specification and model (unit: mm) The specifications of repair patches can be supplied according to customer requirements or in rolls.

As we all know, heat shrink sleeves are a very good anti-corrosion material, widely used in pipeline construction in various construction industries to better protect the use of products. However, sometimes products may cause bubbles due to construction environment, construction methods, or long usage time, which can affect product use. Therefore, we need to clarify the causes and solve them reasonably. After the construction of heat shrink band products, if there are bubbles or bubbles, it will lead to poor sealing. If left unchecked, the bubbles will become larger and larger, causing the product and pipe fittings to fall off. So in order to ensure the use of adhesive tape, it is necessary to master the corresponding solutions and understand the reasons. 1. When storing heat shrink tape, attention should be paid to avoiding light and cool places, and they should not be affected by moisture. If there is moisture, the construction of heat shrink sleeves may cause swelling. 2. Quality issues with heat shrink tape products, such as poor base materials and inappropriate irradiation doses, can all lead to non fire resistance and large area delamination of the heat shrink tape. During the construction process of heat shrink sleeves, the primer was applied unevenly and the tension of the heat shrink sleeve was insufficient. 4. The construction of workers is not standardized. When shrinking, it is necessary to start from the middle position and slowly heat evenly, from the bottom of the pipe to the top of the pipe, in order to make it shrink more evenly. After the shrinkage is completed, special attention should be paid when tempering. The surface temperature of the pipe should be kept above 120 degrees Celsius for three to five minutes, which can make the inner layer of adhesive melt more fully and ensure its sealing, Especially for reinforced heat shrink bands with a thickness of over 2.0mm, their construction should be standardized. 5. Failure to blow out the pipes before construction results in sand and dust, especially in windy and sandy environments, which can cause the surface of the primer to be coated with sand and dust, affecting the adhesion between the tape and the primer. Areas that are not properly adhered are prone to bulging. The reasons for the occurrence of bubbles in the heat shrink band need to be comprehensively analyzed. In order to eliminate them, it is necessary to strictly follow the production process requirements and standardize the construction during the initial construction Based on the above understanding, the reasons and solutions for the occurrence of bubbles in heat shrink sleeves are discussed. Therefore, in order to avoid this phenomenon during construction, in addition to following the above operations, regular inspections and maintenance should also be carried out to ensure quality and effectively improve usage efficiency. 6. Selection of heat shrink bands Different types of heat shrink tapes have different materials and processing techniques. When selecting heat shrink tapes for 2PE Heat Shrink Tape, 3LPE Heat Shrink Sleeves, and 3LPP Wrap Around Sleeves, it is important to choose high-quality and finely crafted heat shrink tapes to reduce the generation of bubbles. For more detailed information on solving the cause of bubble bulges, you can directly contact our technical department.

There are various types of metal pipes, including ordinary steel pipes, galvanized steel pipes, stainless steel pipes, copper pipes, stainless steel lined plastic composite pipes, ductile iron pipes, and so on. Except for a few exceptions, most metal pipelines require anti-corrosion treatment. There are various mainstream methods for pipeline anti-corrosion, especially for external anti-corrosion of water and sewage pipelines, which include several main types such as epoxy coal tar pitch, epoxy resin coating, and polyethylene jacket coating. These anti-corrosion methods can usually be used for internal anti-corrosion, provided that they do not involve drinking water. Internal anti-corrosion usually uses water-based anti-corrosion products such as cement mortar and epoxy resin coating. The order of different types of anti-corrosion coatings, pipeline laying types, and anti-corrosion operations is as follows: 1. Common types and comparisons of anti-corrosion coatings for sewage pipelines: 1. Type of anti-corrosion a. Epoxy coal tar pitch anti-corrosion layer: composed of epoxy resin, coal tar pitch, curing agent and anti rust pigment, it has high strength, good insulation performance, water resistance, heat resistance, corrosion medium resistance, and antibacterial properties. Suitable for anti-corrosion of underwater pipelines and metal structures. The construction is relatively simple, using cold coating technology, safe operation, and less use of machinery. b. Polyethylene coating layer: The polyethylene plastic is thermoplastic onto the surface of the pipeline through a specialized machine, forming a hard plastic shell tightly bonded to the pipe wall. Has good application performance, mechanical strength, and suitable temperature range. It is one of the high-performance anti-corrosion coatings. c. Epoxy resin coating: There are various types of epoxy resin anti-corrosion materials, such as epoxy water-based coatings and epoxy powder coatings. Among them, the epoxy powder coating sprays the powder onto the treated pipe to form a uniform, continuous, and sturdy anti-corrosion film. Thermosetting epoxy powder coating is suitable for pipeline anti-corrosion in harsh environments such as high salt and alkali soils, high salt seawater, and desert areas. Epoxy water-based coatings are used to prevent corrosion by brushing or roller coating pipelines. These materials must meet relevant hygiene and safety requirements when used in drinking water pipelines. d.

The underground pipeline network is the "capillaries" of a city, responsible for the operation of people's daily lives, and is closely related to the quality of the city and the happiness of the people. The types of urban pipeline engineering mainly include water supply pipelines, drainage pipelines, gas pipelines, thermal pipelines, power cables, etc. For deeply buried pipelines, corrosion protection is a complex issue with many influencing factors. Pipeline anti-corrosion is a very niche and segmented industry, which is extremely important for the development and safety of cities. Science popularization: What is pipeline anti-corrosion? Corrosion prevention of pipes refers to measures taken to slow down or prevent the erosion and deterioration of pipelines under the chemical and electrochemical effects of internal and external media, or the metabolic activities of microorganisms. Why do we need to carry out pipeline anti-corrosion? Most oil and gas pipelines are located in complex soil environments, and the medium being transported is also corrosive, so both the inner and outer walls of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, not only interrupting transportation, but also polluting the environment, and may even cause fires, causing harm.Wrapping Materials Application Tooling be used matched with Cold-Applied Polymeric Tape covered ,Innerwrap Tape,Outerwrap Tape,UV-Resistant Tape,Petrolatum Coating System,Double Sided Adhesive Tape Independent innovation drives transformation and upgrading Technological innovation produces high-quality products, which is precisely due to persistent technological research and development.

During the year-round operation of water supply pipelines, due to physical, chemical, electrochemical, and microbiological effects, rust scale gradually forms along the inner wall of the pipeline. As the pipeline age increases, the rust scale continuously thickens, resulting in a decrease in the water flow section. The water inside the pipeline flows along the rust scale, and the hygiene condition of the rust scale will directly affect the water quality of the water supply. Since the existence of water supply projects around the world, people have been tirelessly exploring and researching the corrosion mechanism, anti-corrosion methods, coating structures, etc. of buried metal pipelines, and various anti-corrosion systems have been formed. The pipes used in the water supply network are generally divided into metal pipes and non-metal pipes. From the current pipeline network, large diameter pipes generally use metal pipes, including cast iron pipes, ductile iron pipes, and steel pipes. Small diameter pipes generally use non-metallic pipes, including nylon pipes and PPR pipes for water supply. However, some pipes and fittings are still connected by steel pipes or steel fittings. Due to the lower winter temperatures in the north, both trunk pipelines and urban pipeline networks are generally buried underground, which requires high anti-corrosion requirements for the pipeline network. Good anti-corrosion can avoid water leakage caused by pipeline corrosion, increase friction inside the pipeline, and pollute water quality. On the contrary, it can bring great trouble to the pipeline network, indicating how important pipeline anti-corrosion is for the pipeline network. 1. Corrosion of pipelines Corrosion is a type of damage caused by the chemical and electrochemical reactions of metals in the surrounding medium. Metal corrosion can be divided into chemical corrosion and electrochemical corrosion according to their properties. Chemical corrosion is the process in which a metal directly comes into contact with a medium and undergoes chemical reactions, resulting in the dissolution of metal ions. Electrochemical corrosion is the electrolysis process that occurs in a primary battery composed of metals and electrolytes. Metals generally undergo electrochemical corrosion in electrolyte solutions such as soil, water, or moisture. The causes of external corrosion of buried pipelines are quite complex, generally summarized into the following three reasons: 1. Electrochemical corrosion - Due to the complex mixture of solid, liquid, and gaseous substances in soil, which has the characteristics of electrolyte solutions, the exposed metal in buried pipelines forms a primary battery with the soil electrolyte, leading to electrochemical corrosion of the metal. 2. Corrosion of pipelines by stray currents - due to external leakage, stray currents in the soil pass through the pipeline, resulting in electrolysis and causing pipeline corrosion. 3. Corrosion caused by bacterial action - According to research, the corrosion behavior of different types of bacteria varies under different conditions when microorganisms participate in the corrosion process. Investigation and research on corrosion of buried pipelines have shown that damage to the insulation layer on the outer wall of buried pipelines is the main cause of soil corrosion. In order to ensure long-term safe production of pipelines, in response to the characteristics of soil corrosion, the following ways can be taken to prevent the occurrence of corrosion and reduce the degree of corrosion: (1) Select corrosion-resistant pipes; (2) Increase the transition resistance between the pipeline and the soil, reduce the corrosion current, and use insulation layers such as epoxy coal tar anti-corrosion coating, adhesive tape, epoxy powder, and three-layer PE to increase the resistance of the insulation layer and improve its density (without pinholes), thereby minimizing the corrosion current; (3) Using electrical protection (cathodic protection and sacrificial anode protection), general electrical protection should be combined with insulation layer protection to reduce the consumption of protection current. 2. Corrosion prevention of pipelines The outer wall is mostly coated with epoxy in China. In recent years, China has successively researched and developed anti-corrosion technologies such as polyethylene cold wound tape (two-layer structure), Visco Elastic Coating Materials/fusion bonded epoxy powder coating, Cold Applied Polymer Tape and Heat Shrinkable Sleeves, achieving good anti-corrosion effects. However, in practical applications, the shortcomings of these anti-corrosion technologies have also been exposed, such as poor adhesion of two-layer polyethylene jackets, low mechanical properties of fusion bonded epoxy powder layers, and difficulty in ensuring the construction quality of polyethylene adhesive tapes. Therefore, some European countries have developed and successfully applied heat shrink material technology since the 1980s, This is currently considered the most advanced external anti-corrosion technology for pipelines internationally. HDPE polyethylene coating is widely recognized as one of the most promising anti-corrosion materials due to its excellent physical and mechanical properties, good chemical corrosion resistance, extremely low water and oxygen permeability, and low environmental pollution. However, the poor adhesion between non-polar polyethylene coatings and polar steel pipe surfaces has not been effectively resolved yet. The most commonly used inner walls are solvent-free epoxy anti-corrosion coatings and IPN interpenetrating network anti-corrosion coatings. 3. Anti corrosion process of pipelines Pipeline coating: Coating the outer wall of buried metal pipelines can significantly improve their service life. 1. Rust removal process. The rust removal process is more convenient than other anti-corrosion processes. Simply use sandpaper, wire brush, or electric grinder to remove floating rust, welding slag, oil stains, and loose substances on the surface of the coated workpiece, and wipe it clean until it is flat and dry before applying. It should be emphasized that the surface of the coated workpiece must be cleaned of floating rust, oil stains, and other debris, otherwise it will affect the adhesion and coating quality of the coating. 2. Coating process. Brushing, spraying, rolling and other methods can be used for coating. a. Ordinary anti-corrosion type (two bottoms and two sides). One primer → One primer → One topcoat → One topcoat. Dry film thickness approximately 200 μ M. Wet film thickness is about 250 μ M, Liquid Epoxy Coatings covered Epoxy Primer,High Temperature Epoxy Primer,Field-Applied Coatings Materials.
