Product Description:
3LPE Steel Pipe Coating Production Line
Product Overview:
The 3LPE (Three-Layer Polyethylene) Steel Pipe Coating Production Line by Qingdao Huashida Machinery Co., Ltd. is engineered for high-performance anti-corrosion coating of steel
pipes. This line supports pipe diameters ranging from 159mm to
1400mm, with an extrusion capacity up to 350 kg/h, customizable to
specific production requirements.
This advanced production line is the result of years of dedicated
development and innovation, fulfilling the increasing market demand
for durable, efficient, and high-performance anti-corrosion
solutions.
3-Layer PE Coating System Composition:
The 3LPE anti-corrosion coating system comprises:
- Fusion-Bonded Epoxy (FBE) Primer Layer
- Thermosetting, non-toxic coating that cures into a high molecular
weight, cross-linked structure.
- Provides excellent chemical corrosion resistance and superior
adhesion.
- Polymer Adhesive Middle Layer
- Typically a polyolefin copolymer (e.g., vinyl copolymer) that
chemically bonds with both the epoxy primer and polyethylene top
layer.
- Polyethylene (PE) Top Layer
- Ensures high mechanical protection and environmental resistance,
ideal for buried pipelines.
This 3-layer coating structure ensures superior adhesion, excellent
mechanical strength, and long-lasting anti-corrosion performance,
making it widely used in oil & gas pipelines, urban gas
distribution, and water transmission lines.

Applications:
Application
The three-layer PE process, utilizing epoxy powder coating as the
bottom layer, bonding and bundling through polyethylene PE and
adhesive, is extensively utilized for the anti-corrosion treatment
of steel pipes. This method is commonly applied in industries such
as oil, natural gas, chemicals, and water pipelines.
