3PE-coated steel pipe
2022-05-07
3PE‑coated steel pipe refers to an externally coated steel pipe with a three‑layer polyethylene protective layer, and it is a commonly used type of corrosion‑resistant pipeline in the petroleum industry. As for 3PE‑coated steel pipes, precision seamless steel pipes are high‑precision tubes produced through cold drawing, cold rolling, or subsequent processing; their full name is cold‑drawn or cold‑rolled precision seamless steel pipe.

As for 3PE‑coated steel pipes, precision seamless steel pipes are high‑precision tubes produced through cold drawing, cold rolling, or subsequent processing; their full name is “cold‑drawn or cold‑rolled precision seamless steel pipe.”
The outer layer of 3PE‑coated steel pipe is a high‑density polyethylene anti‑corrosion coating, while the intermediate layer consists of a copolymer adhesive containing functional groups with branching structures. The innermost layer in contact with the steel pipe surface is an epoxy powder‑based anti‑corrosion coating. 3PE reinforced‑grade coated steel pipes are widely used and produced in large quantities, primarily serving as pipelines for fluid transport or as structural components. Standard‑grade 3PE‑coated steel pipes are typically manufactured by rolling alloy structural steels, ordinary carbon structural steels, or low‑alloy structural steels.
3PE‑coated steel pipes are widely used in the petroleum pipeline industry, with base materials including spiral welded pipes, straight‑seam welded pipes, and seamless steel pipes. The three‑layer polyethylene (3PE) anti‑corrosion coating boasts excellent resistance to water vapor permeation, superior corrosion protection, and robust mechanical properties.
