Description :
The thickness standard for 3PE anti-corrosion steel pipes: There are mainly two types of 3PE anti-corrosion steel pipes based on the thickness of the anti-corrosion layer: ordinary grade and reinforced grade. So, how to distinguish between the two? ***The convenient detection method is a thickness gauge. Their fundamental difference lies in the thickness, which is around 2.0mm for common specifications 219-478, while the reinforcement level is around 2.7mm. Their prices differ by about 7 yuan per square meter. The choice of anti-corrosion grade depends on the specific requirements of the customer. If it is used for ordinary casing external anti-corrosion, ordinary grade is more than sufficient. If it is used for direct fluid flow, such as acid and alkali, natural gas, etc., reinforced grade should be used as much as possible.
The current development status of the 3PE anti-corrosion steel pipe industry is still good, which we are familiar with in the anti-corrosion industry. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water vapor permeability resistance, and mechanical properties. 3PE anti-corrosion is currently an advanced and mature external wall anti-corrosion technology. It has the advantages of good anti-corrosion performance and long service life, and is widely used in natural gas transportation, oil transportation, heating, refrigeration and other project engineering. 3PE anti-corrosion steel pipe has the characteristics of high circulation capacity and low engineering cost. The inner wall of the pipeline is lubricated, and there is relatively less scaling. The roughness ratio of the inner and outer surfaces of the PE pipe is definitely 1/20 of that of the steel pipe. Under the same diameter, length, and pressure, the flow of the PE pipe can be about 30% larger than that of the steel pipe, so the economic advantage is appropriately high.






Directly buried 3PE anti-corrosion steel pipe wholesale manufacturer: 3PE anti-corrosion steel pipe base materials include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has excellent corrosion resistance, water vapor permeability resistance, and mechanical properties. The 3PE anti-corrosion steel pipe has an additional layer of epoxy powder, which has good corrosion resistance, good mechanical properties, and strong resistance to cathodic stripping. Although it has the advantages of strict surface treatment, poor weather resistance, and high water absorption rate, it is suitable for buried pipelines and submarine pipelines, with a coating thickness of only 0.3-0.5 millimeters and a service life of up to 40-50 years.
Directly buried 3PE anti-corrosion steel pipes are commonly used in buried gas transportation and water supply and drainage projects. In the three-layer structure, the main function of the fusion bonded epoxy powder coating is to form a continuous coating film, which is directly bonded to the surface of the steel pipe and has good chemical corrosion resistance and cathodic stripping resistance; Reacts with the active groups of the intermediate layer adhesive to form a chemical bond, ensuring that the overall anti-corrosion layer has good adhesion at higher temperatures. The intermediate layer is usually a copolymer adhesive, which is mainly composed of polyolefin. Currently, ethylene based copolymer adhesives are widely used.
3PE anti-corrosion steel pipe is one of the commonly used anti-corrosion pipelines in China, which refers to a three-layer structure polyolefin coated external anti-corrosion steel pipe. 3PE anti-corrosion steel pipes are generally composed of three layers of structure, one layer of epoxy powder, the second layer of adhesive, and the third layer of polyethylene. In practical operation, the three materials are mixed and integrated into one, and processed to firmly bond with the steel pipe to form an excellent anti-corrosion layer. Its processing methods are generally divided into two types: winding and circular mold wrapping.






To understand the wholesale and customized prices of 3PE anti-corrosion steel pipes, it is necessary to know the basic composition and structure of 3PE anti-corrosion steel pipes. The main components of 3PE anti-corrosion steel pipes are steel pipes and anti-corrosion coatings, but their production costs are far more than that. The prices we quote are based on the price per meter, which includes items such as workers' wages, electricity bills, equipment wear and tear fees, and site rent. In the context of almost transparent prices among manufacturers, in addition to strict quality control, there is also a price barrier. 80% of the competition in a 3PE anti-corrosion steel pipe project is determined by price, so in addition to good quality, it is also necessary to be competitive in terms of price. The main way to reduce prices is to reduce the waste of anti-corrosion materials and try to concentrate the remaining anti-corrosion materials for future use. Another option is to search for steel pipe manufacturers with affordable prices, as high-quality and cost-effective steel pipes can also reduce costs. These two items are enough to make our product prices competitive to a certain extent.
The application scope of 3PE anti-corrosion steel pipe manufacturers is as follows: sewage treatment: sewage treatment discharge pipes, sewage pipes, and biological pool anti-corrosion engineering agriculture: agricultural irrigation pipes, deep well pipes, drainage pipes and other network coal mines: suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks in coal mines. Power plant: Process water waste residue and return water transportation pipeline for thermal power plants. Firefighting: The applicability of water supply pipelines for sprinkler and sprinkler systems. Highways: Cable protection sleeves for power, communication, highways, etc. Municipal engineering: suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines. From practical usage, if the pipeline is usually at room temperature and filled with water, the corrosion on the inside of the weld is usually not very severe. But if the water is cut off or the heating water is supplied, the degree of corrosion is still quite severe.
