3pe anti-corrosion steel pipe is a steel pipe with a base material including seamless steel pipe, spiral steel pipe and straight seam steel pipe after anti-corrosion coating processing. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the oil pipeline industry because of its good corrosion resistance, moisture permeability resistance and mechanical properties.
(1) Structural composition
3PE anticorrosion is generally composed of 3 layers:
First layer epoxy powder (FBE>100um)
The second adhesive (AD) is 170 ~ 250um
The third layer of polyethylene (PE) 1.8-3.7mm
In actual operation, the three materials are mixed into one, and after processing, they are firmly combined with the steel pipe to form an excellent anti-corrosion layer. Its processing methods are generally divided winding type and circular die coating type.
3PE anticorrosive steel pipe coating (three layers of polyethylene anticorrosive coating) is a new anticorrosive steel pipe coating produced by combining the 2PE anticorrosive layer in Europe and the widely used epoxy powder anticorrosive steel pipe coating (FBE) in North America. It has been recognized and used around the world for more than a decade.
(2) Product use
The coating of 3PE anti-corrosion steel pipe is an epoxy powder anti-corrosion coating that is in contact with the surface of the steel pipe, and the middle layer is a copolymerization adhesive with branch structural functional groups. The surface layer is high-density polyethylene anticorrosive coating.
3pe anti-corrosion coating combines the high impermeability and high mechanical properties of epoxy resin and polyethylene materials. So far, it is recognized as the best and best performance pipeline anti-corrosion coating in the world, so it is applied in many projects.
3PE anticorrosive steel pipe is suitable for coal mine underground water supply and drainage, underground grouting, positive and negative pressure ventilation, gas extraction, fire sprinkler and other pipe networks. Thermal power plant process water waste residue, return water transmission pipeline. It has excellent applicability to the water supply pipeline of the anti-spray and sprinkler system. Electric power, communication, highway and other cable protection sleeve. It is suitable for high-rise building water supply, heat supply network heating, tap water engineering, gas transmission, buried water transmission and other pipelines. Oil transmission pipeline, chemical and pharmaceutical, printing and dyeing industries to transport corrosive media process pipeline. Sewage treatment discharge pipe, sewage pipe and biological tank anticorrosion engineering. Agricultural irrigation pipes, deep well pipes, drainage pipes and other networks.
Recently, a batch of 3pe anticorrosive pipes supplied by us have been put into use in the Nigerian market to provide our product services for the NNPC project.
