API DN2000 3PE Anti Corrosion Pipe , Carbon Steel Pipeline

Direct supply of 3PE anticorrosive steel pipe for municipal gas pipeline

The anti-corrosion layer of 3pe anti-corrosion steel pipe is particularly important for the service life of buried pipelines. For pipelines of the same material, some are buried in the ground for decades without corrosion, and some leak in two years. It is because they have chosen a different outer anti-corrosion layer. Polyethylene three-layer structure safety protection layer is also called three-layer PE (3PE), which is an excellent anti-corrosion technology introduced from overseas in recent years. Its full name is fused epoxy resin/flame retardant plastic polyethylene structure safety protection layer, and its structure is composed of the following three layers: its full name is fused epoxy resin/flame retardant plastic polyethylene structure safety protection layer, structure It consists of the following three layers: the bottom layer is fused epoxy resin (≥80μm); the inner layer is adhesive (170 to 250μm); the overall surface layer is flame-retardant plastic polyethylene (about 3mm). The total thickness of the safety protection layer is about 1.8-3.7mm. In the three-layer structure, the key function of the fusion-bonded epoxy powder coating is: to produce a continuous coating, which is immediately bonded to the surface of the seamless steel pipe, and has very good solvent corrosion resistance and negative electrode separation characteristics; and the inner layer of glue The specific functional groups of the adhesive reflect organic chemical bonding, ensuring that the overall anti-corrosion layer has excellent adhesion at higher temperatures.

The key way for manufacturers of buried 3PE anti-corrosion steel pipes to reduce prices is to reduce the consumption of anti-corrosion raw materials and ensure that the remaining anti-corrosion raw materials are used for the next application as much as possible. Another thing is to find a seamless steel pipe manufacturer with a low price. Cheap and high-quality seamless steel pipes can also reduce costs. These two items can make our product offer a certain competitive ability. The three-pe anticorrosive coating combines the high impermeability grade and high physical properties of epoxy resin and polyethylene raw materials. So far, it is the pipeline anti-corrosion coating with practical effects and characteristics that is recognized worldwide, and it has been used in many engineering projects.

The three-layer structure polyethylene anti-corrosion layer (3PE) combines the high-quality characteristics of the fusion-bonded epoxy powder coating and the extruded polyethylene anti-corrosion layer, and combines the page characteristics and solvent resistance characteristics of the fusion-bonded epoxy powder coating. Combined with the advantages of mechanical equipment maintenance features of the extruded polyethylene anticorrosive layer, the respective characteristics are significantly improved. Therefore, it is very excellent as an outer safety protection layer for buried pipelines. According to the detailed introduction of related materials, the three-layer PE can make the service life of the buried pipeline reach 50 years. ⑶ The anti-corrosion of the fixed port shall be carried out after the electric welding and water pressure test reach the standard. First, lap the anti-corrosion layer on both sides of the fixed port to the surface layer to eliminate cleanliness. Then carry out anti-corrosion solution.
