High Efficiency O-Type 3LPE FBE Steel Pipe Coating Line Water Supply Pipelines

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

The High Throughput O-Type 3LPE FBE Steel Pipe Coating Line is a professional fully automatic small-bore steel pipe anti-corrosion coating system, specially customized and optimized for oil and gas gathering line anti-corrosion projects. Different from traditional modified large-diameter pipe coating equipment, this dedicated O-Type round die 3LPE coating machine is independently calibrated for 76-325mm small-bore steel pipes, fully matching 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 one-stop anti-corrosion production process: automatic steel pipe conveying, external shot blasting rust removal up to Sa2.5 standard, intelligent dust collection system, medium-frequency induction heating, electrostatic FBE epoxy powder spraying, hot melt adhesive extrusion, exclusive O-Type round die 2LPE/3LPE co-extrusion, circulating water spray cooling, automatic pipe end grinding and beveling, hydraulic & pneumatic control, finished pipe quality inspection and full PLC intelligent control system. Supporting single-operator automatic operation, the line delivers stable high throughput over 150m²/h, realizing high-efficiency, standardized and high-precision oil gas pipeline anti-corrosion coating.

Equipped with patented O-Type round die co-extrusion technology, this small-bore pipe coating equipment achieves 360° uniform and consistent 3LPE coating thickness on 76-325mm steel pipes. It requires no repeated manual adjustment during pipe size switching, completely solving common industry points of traditional spiral coating lines - uneven coating thickness, low production efficiency and high defective rate when processing small-diameter steel pipes. Finished 3LPE coated steel pipes provide superior comprehensive anti-corrosion performance, with excellent resistance to acid, alkali, salt and oxidative corrosion. It perfectly adapts to harsh underground oilfield working environments and effectively extends the service life of buried oil and gas gathering pipelines.

Widely applicable for oil & gas gathering lines, municipal water supply pipelines, urban natural gas distribution networks and industrial fluid conveying pipelines, this high-throughput O-Type 3LPE coating line is the most cost-effective professional anti-corrosion coating equipment dedicated to global small-bore steel pipe engineering and infrastructure projects.

The standardized mature production workflow guarantees reliable coating adhesion, consistent coating thickness and high finished product qualification rate for small bore 3LPE FBE anti-corrosion coating:

• Steel pipe screw conveyor feeding
• External shot blasting rust removal (Sa2.5 surface preparation standard)
• Medium frequency uniform induction heating
