Potable Water O-Type 3LPE FBE Steel Pipe Coating Line for Water Supply

This O-Type 3LPE FBE Steel Pipe Coating Line is a professional, fully automatic small-bore water supply pipeline anti-corrosion coating system, purpose-engineered and independently calibrated for 76–325 mm potable water supply pipeline coating projects. As the only O-Type coating line in this product family explicitly positioned for potable water supply infrastructure, this dedicated O-Type round-die 3LPE FBE coating machine leads with the most critical water supply buyer requirement: zero-toxicity internal FBE coating — the only anti-corrosion coating type approved for direct contact with transported drinking water without harmful substance leaching.

Unlike modified large-diameter pipe coating equipment that runs small-bore water supply pipe below its intended range, this high-efficiency O-Type water supply pipe coating line is independently calibrated for 76–325 mm small-bore steel pipes, fully matching the dimensional standards and anti-corrosion requirements of municipal water supply distribution pipelines, urban natural gas distribution networks, and buried water supply infrastructure projects. The O-Type round-die co-extrusion technology achieves 360° uniform 3LPE FBE coating thickness on 76–325 mm water supply pipes, requiring no repeated manual adjustment during pipe size switching — completely solving the common pain points of uneven coating thickness and high defective rates when processing small-diameter water supply pipe on traditional spiral coating lines.

This integrated small-bore water supply FBE 3LPE coating line covers the full one-stop anti-corrosion production process: automatic steel pipe conveying, external shot blasting rust removal to Sa2.5 standard, intelligent dust collection, medium-frequency induction heating, electrostatic FBE epoxy powder spraying (200–400 μm anti-corrosion primer layer), hot melt adhesive extrusion, exclusive O-Type round-die 2LPE/3LPE co-extrusion, circulating water spray cooling, automatic pipe end grinding and beveling compliant with DIN 30670 and BS EN 10329 international water supply pipeline coating standards, and full PLC intelligent control — delivering stable ≥150 m²/h high throughput across the full 76–325 mm water supply pipeline diameter range.

The standardized, mature production workflow guarantees reliable 3LPE FBE coating adhesion, consistent coating thickness, and a high qualification rate for 76–325 mm water supply pipeline anti-corrosion coating:

1. Steel pipe screw conveyor feeding
2. External shot blasting rust removal (Sa2.5 surface preparation)
3. Medium-frequency uniform induction heating
4. Electrostatic FBE epoxy powder spraying (200–400 μm standard water supply pipeline anti-corrosion primer layer)
5. O-Type round-die hot-melt adhesive and 3LPE polyethylene synchronous co-extrusion
6. Circulating water spray cooling
7. Automatic steel pipe conveying
8. Precision pipe end grinding and beveling (compliant with DIN 30670 and BS EN 10329 international water supply pipeline anti-corrosion standards)
9. Finished water supply pipe quality inspection and unloading

• Zero-Toxicity Internal FBE for Potable Water Supply: Internal Fusion Bonded Epoxy (FBE) coating meets potable water supply pipeline safety standards — the only internal coating type approved for drinking water infrastructure without harmful substance leaching into transported water. The low-friction smooth inner wall also reduces fluid transmission resistance and improves water supply network conveying efficiency.
• Professional Water Supply Pipeline Custom Design: Exclusive O-Type round-die co-extrusion structure professionally calibrated for 76–325 mm small-bore water supply steel pipes — eliminates the uneven coating quality and low-efficiency defects of refitted large-diameter coating lines running small water supply pipe below their intended range.
• ≥150 m²/h High Throughput, 0.5% Failure Rate: Sustained high production capacity supporting full-spec continuous production for all 76–325 mm water supply pipeline diameters; all-weather stable operation ensures on-time delivery for large-scale municipal water supply anti-corrosion orders.
• PLC Intelligent Single-Operator Automation: PLC intelligent control system for a fully automated water supply pipe coating workflow; equipment long-term failure rate below 0.5%; saves over 40% labor cost versus traditional semi-automatic small-bore water supply pipe coating equipment.
• DIN 30670, BS EN 10329 and SY/T 0413 Certified: CE and ISO9001 certified water supply pipeline coating line, fully compliant with international 3LPE FBE coating standards — meeting global municipal water supply, natural gas, and infrastructure project acceptance requirements.
• Complete Turnkey One-Stop Water Supply Solution: Full lifecycle turnkey services including pre-sales technical design, factory layout planning, on-site installation, commissioning, operator training, and 24/7 remote technical support for water supply pipeline anti-corrosion production.
• National Expert R&D Workstation: Backed by a national expert R&D workstation offering personalized O-Type 3LPE FBE water supply pipe coating process customization and continuous technical upgrading for small-bore water supply steel pipe anti-corrosion production.
