High Throughput O-Type 3LPE FBE Steel Pipe Coating Line for Oil Gas Gathering

This High Throughput O-Type 3LPE FBE Steel Pipe Coating Line for Oil Gas Gathering is a complete, purpose-built small-bore oilfield gathering line anti-corrosion coating system - not a scaled-down version of large-bore equipment, but a fully integrated line sized and calibrated specifically for the 76-325mm diameter range that oilfield gathering pipelines demand. The complete system integrates steel pipe transmission, external shot blasting to Sa2.5, dust collection, medium-frequency induction heating, electrostatic FBE epoxy powder spraying, hot melt adhesive extrusion, O-Type round-die 3LPE/2LPE polyethylene co-extrusion, water spray cooling, automated pipe end grinding/beveling, hydraulic/pneumatic operation, inspection, and full PLC automatic control - all managed by a single operator at ≥ 150m²/h high throughput.

Unlike spiral-conveyor large-diameter coating lines running inefficiently below their intended range, this O-Type round-die co-extrusion coating line delivers uniform, continuous 3LPE coating thickness around the full pipe circumference without manual adjustment between pipe sizes - the critical technical advantage of O-Type extrusion for small-bore oil gas gathering line pipe anti-corrosion coating.

With exceptional resistance to chemical degradation, the 3LPE O-Type coated small-diameter gathering line pipe demonstrates outstanding stability against acids, bases, salt solutions, and oxidizers - enabling safe oil and gas transmission in harsh oilfield underground environments while extending gathering pipeline service life significantly beyond uncoated alternatives. Applications span across oil and gas gathering lines, municipal water supply distribution, natural gas distribution networks, and industrial fluid transportation systems where small-bore pipe demands precision-calibrated FBE 3LPE coating equipment rather than oversized machinery.

The standardized O-Type 3LPE FBE coating workflow ensures uniform coating thickness and stable adhesion across the full 76-325mm gathering line diameter range:

1. Pipe upload via screw conveyor
2. External shot blasting rust removal (Sa2.5)
3. Medium-frequency induction heating
4. Electrostatic FBE epoxy powder spraying (200-400μm base layer)
5. O-Type round-die hot melt adhesive and 3LPE polyethylene co-extrusion
6. Water spray cooling
7. Pipe screw conveyor
8. Automated pipe end grinding/beveling (DIN 30670/BS EN 10329)
9. Finished pipe unloading
