External 3PE anticorrosive internal epoxy resin anticorrosive steel tube

2pe-3pe anticorrosive steel tube

Material analysis of 2PE-3PE anticorrosive steel tube

The 2pe-3pe anticorrosive steel tube base material includes seamless steel tube, spiral steel tube and straight seam steel tube.Three-layer polyethylene (3PE) anticorrosive coating has been widely used in petroleum pipeline industry for its excellent corrosion resistance, water and gas permeability and mechanical properties.

Introduction to the anticorrosive coating of 2PE-3PE steel tube

2pe-3pe anticorrosion generally consists of three layers:

First layer epoxy powder (FBE>100um)

Second layer adhesive (AD) 170 ~ 250um

Third layer polyethylene (PE) 2.5 ~ 3.7mm

In actual operation, the three materials are mixed and integrated into one, which can be firmly combined with the steel pipe to form an excellent anticorrosive layer after processing.Its processing mode is generally divided into two types: winding type and round mold wrapping type.

Advantages of 2pe-3pe anticorrosive steel pipe anticorrosive layer:

The coating of 2pe-3pe anticorrosive steel tube is epoxy powder anticorrosive coating in contact with the bottom layer and the surface of the steel tube.The surface layer is high density polyethylene anticorrosive coating.3PE anticorrosive steel tube coating, also known as (three layers of polyethylene anticorrosive coating), is a new anticorrosive steel tube coating produced by the combination of Europe's 2PE anticorrosive coating and the widely used epoxy powder anticorrosive steel tube coating (FBE) in North America.Has been widely recognized and used in the world.
