76-325mm O-Type 3LPE FBE Steel Pipe Coating Line for Natural Gas Distribution

High Throughput O-Type 3LPE FBE Steel Pipe Coating Line is a professional fully automatic small-bore pipeline anti-corrosion coating system specially customized for oil and gas gathering line anti-corrosion. This dedicated O-Type round die 3LPE coating machine is independently calibrated and optimized for 76-325mm small-bore steel pipes, perfectly matching the dimensional standards and anti-corrosion requirements of oilfield gathering pipelines, municipal gas distribution pipelines and industrial fluid transmission pipelines.

This integrated small bore FBE 3LPE coating line covers the full production process with a stable high throughput of ≥150m²/h, realizing high-efficiency and standardized oil gas pipeline anti-corrosion coating.

The standardized mature workflow ensures stable adhesion, uniform coating thickness and high finished product qualification rate for small bore 3LPE FBE coating:

1. Pipe screw conveyor feeding
2. External shot blasting rust removal (Sa2.5 standard)
3. Medium-frequency uniform induction heating
4. Electrostatic FBE epoxy powder spraying (200-400μm standard primer layer)
5. O-Type round-die hot melt adhesive & 3LPE polyethylene synchronous co-extrusion
6. Water spray circulating cooling
7. Automatic pipe conveying
8. Precision pipe end grinding & beveling (Compliant with DIN 30670 / BS EN 10329 international standards)
9. Finished pipe inspection & unloading

• Professional Oil Gas Gathering Line Custom Design: Exclusive O-Type round-die co-extrusion structure specially developed for 76-325mm small-bore steel pipes, avoiding low efficiency and uneven coating defects of refitted large-diameter coating lines.
• High Throughput Stable Production: Sustained high output ≥150m²/h, stable full-range production for all small-bore pipe specifications.
• Ultra-Low Failure Rate & Full-Automatic Operation: Equipped with PLC intelligent control system, the whole line runs continuously with a failure rate lower than 0.5%.
• Great Labor Cost Saving: Single-person automatic operation mode reduces manual participation greatly, cutting labor cost by 40%.
• International Standard Compliance: CE and ISO9001 certified equipment, fully compliant with DIN 30670, BS EN 10329, SY/T 0413 oil pipeline anti-corrosion specifications.
• One-Stop Turnkey Service: Provides free pre-sales scheme design, factory layout planning, on-site installation, equipment commissioning and professional operator training.
• Professional Technical Backing: Supported by national high-end plastic machinery expert workstation, providing personalized O-Type 3LPE FBE coating process customization.
