Automatic 3LPE Coating Pipe Production Line with PLC Control System and CE ISO Certification for Durable Pipeline Solutions
Huashida 3LPE steel pipe blasting & coating equipment is designed for water, gas, and oil pipeline anti-corrosion processing according to customers' specific requirements. The production line includes internal and external shot blasting for derusting, dual Fusion Bonded Epoxy (FBE) powder or liquid coating, PE/PP film wrapping, PE end grooving system, and more.
Huashida's 3PE anti-corrosion coating production line features superior equipment quality, an affordable price, and outstanding service. The three-layer PE pipelines produced using this production line rank at the forefront of the oil and gas transportation industry.
- Pipe loading
- External derusting
- Inner blowing cleaning
- Epoxy coating application
- Adhesive application on the epoxy layer
- PE jacket coating
- Water cooling
- Coating layer inspection
- Pipe edge treatment
- Finished pipe conveyance
- Pipe unloading
The 3PE anti-corrosion coating production line can handle pipes with diameters ranging from Φ57mm to Φ1620mm, enabling one-stop pipeline operations.
The three-layer PE anti-corrosion structure combines the excellent anti-corrosion properties of epoxy coatings and extruded polyethylene. The epoxy coating offers superior interface characteristics and chemical resistance, while the extruded polyethylene coating provides excellent mechanical protection.
- First Layer: Epoxy powder (FBE > 100µm) - provides basic anti-corrosion protection
- Second Layer: Adhesive (AD) with thickness of 170-250µm - acts as bonding agent
- Third Layer: Polyethylene (PE) with thickness of 2.5-3.7mm - offers robust mechanical protection
This anti-corrosion structure integrates the three materials into one and forms an excellent anti-corrosion layer firmly bonded to the steel pipe. After years of practical application, the buried three-layer outer protective layer has proven to be highly superior with a service life of over 50 years.
