Product Name
3PE 3LPE FBE VUS Insulation Anti-Corrosion Steel Pipe Coating Production Line
Product Description
3PE / 3LPE anti-corrosion steel pipe coating production line is a fully automated industrial coating system designed for factory‑applied external and internal anti‑corrosion protection of steel pipelines. This equipment is widely used in long-distance oil & gas pipelines, urban gas transmission, district heating networks, water supply, sewage disposal, and other buried / overhead pipeline engineering projects.
This multi‑functional production line supports a full range of coating technologies, including:
FBE (Fusion Bonded Epoxy) coating, 2‑layer FBE, 2‑layer PE, 2‑layer PP, 3‑layer PE (3PE / 3LPE) anti‑corrosion coating systems.
The 3‑layer PE (3PE / 3LPE) composite anti‑corrosion structure consists of:
- FBE epoxy powder bottom primer layer
- Polymer adhesive bonding layer
- High‑density polyethylene (PE) outer protective layer
Model Specifications
- Steel pipe 3LPE anti‑corrosion coating line: Pipe diameter 159–4200mm
- Internal & external FBE coating line: Pipe diameter 500–4200mm
- Internal FBE + external 3LPE composite coating line: Pipe diameter 159–4200mm
- Small‑size steel pipe O‑type extrusion 3LPE coating line: Pipe diameter 57–426mm
- Steel bend pipe FBE & 3LPE coating production line
Application & Performance
3PE / 3LPE anti‑corrosion coating is the internationally recognized high‑performance protection technology for buried steel pipelines. It is widely applied in:
- Oil and natural gas transmission pipelines
- Urban gas distribution networks
- Municipal water supply and drainage pipelines
- Industrial fluid transportation pipelines
- Heating network and utility pipelines
This multi‑layer protective system significantly improves pipeline mechanical strength, electrical insulation, waterproof performance, wear resistance, and anti‑aging performance, greatly extending service life and reducing maintenance costs.
