3LPE 3PE Fbe Anti-Corrosion Insulation Coating Line for Trunk Petroleum Transport Pipelines
Description
The steel pipe anti-corrosion coating line, utilized for coating steel pipes of multiple diameters with anti-corrosion materials in a factory, has broad applications in various engineering projects, prominently in heating, gas, and oil extraction industries.
The lines can be applied to FBE,2 layer FBE,2 layer PE,2 layer PP,3 layer PE anti-corrosion coating.
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 three-layer polyethylene anti-corrosion coating, a leading technology, functions as the outermost protective layer for underground pipelines. It is extensively used in the corrosion prevention of gas and oil transmission lines, municipal gas supply systems, water pipes, and other fluid transport conduits, enhancing pipeline mechanical capabilities with superior electrical insulation, waterproofing, durability, and anti-aging features.
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.
The anti-corrosion coating processing line includes:
-steel pipe transmission system
-surface treatment system
-end cutting system
-pipe dust removal system
-pipe heating system
-electrostatic spraying system
-coating system
-water cooling system
-hydraulic and pneumatic system
