spiral steel pipe

spiral steel pipe
Spiral steel pipe is a strip coil as raw material, often warm extrusion molding, spiral to the automatic double wire submerged arc welding process double-sided spiral pipe into pipe joints.

Spiral steel pipe

(1) the volume of raw materials that strip, wire, flux. Before we put into rigorous physical and chemical testing.

(2) of strip head and tail docking, using single or double wire submerged arc welding in steel, rolled by automatic submerged arc welding welding.

(3) before forming, strip after flattening, cutting edge, edge planing, surface cleaning to the transmission and bending process.

(4) by controlling the conveyor on both sides of cylinder pressure electric contact pressure gauge, ensure the smooth conveying the strip.

(5) the external control or internal roll forming.

(6) used to weld gap control device to ensure weld gap to meet the requirement of welding, pipe diameter, misalignment and seam gap have been strictly controlled.

(7) inside welding and welding are used USA Lincoln Electric welding machine for single or double wire submerged arc welding, welding quality so as to obtain stable.

(8) end of the seam welding have been injured on-line continuous automatic ultrasonic inspection apparatus, ensure nondestructive testing coverage rate of 100% of the spiral weld. If defective, automatic alarm and spray marking, production workers and adjust process parameters, the timely elimination of defects.
