The composition of 3-layer PE coating production line
3 layer PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.
3PE anti-corrosion coating production line, is three PE anti-corrosion structure of anti-corrosion pipeline production line, diameter range φ50 ~ φ4200, the use of three anti-corrosion. Namely, a layer of epoxy powder (FBE> 120µm), the second layer of adhesive (ad) 170 ~ 250µm, the third layer of polyethylene (PE) 1.8-4.2 mm.

The intermediate layer is usually a copolymer binder, the main component of which is polyolefin, and is widely used as a vinyl copolymer adhesive. The polar moiety of the copolymer adhesive and the epoxy group of the epoxy primer can react to form hydrogen bonds or chemical bonds to form a good bond between the intermediate layer and the substrate; and the non-polar ethylene moiety has a Good affinity, so the middle layer and the surface layer also has a good bonding performance. Three-layer structure of polyethylene anti-corrosion, as the buried pipe outside the protective layer is very superior, and the technology has been widely used in the West-East Gas and oil field oil supply, urban gas supply, water pipeline used on the anti-corrosion.

Detailed Photos

Corrosion-resistant steel pipes are primarily categorized into two main types: internally treated and externally treated.
Internally treated steel pipes are widely used, relatively low-cost, and utilize a coating to protect the pipe's interior. Externally treated steel pipes are primarily 3PE-coated, a mainstream technology. Qingdao Huashida's 3PE anti-corrosion production line utilizes mature technology, providing highly effective corrosion protection for both the exterior and interior of steel pipes. Suitable for a variety of pipe types, including straight-seam steel pipe and spiral pipe, the line boasts a comprehensive ISO9001-certified quality assurance system, ensuring reliable, end-to-end quality control.

Qingdao Huashida Machinery Co., LTD., founded in 2003, is a global developer, manufacturer and solution provider of plastic extrusion equipment. 70% of its customers come from overseas countries such as Europe, America, the Middle East and Southeast Asia.
