1. Steel pipe anticorrosionTechnical process

Steel pipe into the factory→ Visual inspection → Steel pipe preheating → Shot blasting → Quality inspection, defect handling → Pipe end shield →Dust treatment → Medium frequency heating →Powder electrostatic spraying →Adhesive extrusion → PE extrusion winding→ Roller pressure→ Water cooling→ Quality inspection→ Pipe end processing → Into the next tube platform 

2,Outside anticorrosiveLine composition

   On pipe rack, hydraulic pipe, derusting line transmission line, medium frequency preheating system, shot blasting purging, derusting descaling system, tube surface line under the hydraulic pipe institutions, middle frame, steel pipe purging device, 3 PE coating line hydraulic tube body, 3 PE coating line transmission line, dust processing equipment, electrostatic grounding device, medium frequency heating system, powder electrostatic spraying system, adopting side winding way under the extrusion of the adhesive and PE extrusion system, water cooling system, 3 PE coating line, finished product and test for the hydraulic pipe under the pipe rack, end grinding equipment and automatic control system.

   The accessory system：  Hydraulic station system, air compressor station system, straight pass roller.
