spiral steel pipe

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 into pipe joints. The process adopts the advanced double-sided submerged arc welding, can be in the best position to realize welding, is not easy to appear the wrong side, welding partial and incomplete welding defects, easy to control the quality of welding

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 into pipe joints.
(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.
(9) the air plasma cutting machine to cut a single pipe.
(10) into a single tube, each batch of steel pipe must be strict inspection system first, chemical composition and mechanical properties, the inspection of welds, blending, surface quality of steel pipe as well as a nondestructive inspection, to ensure that the pipe manufacturing process after passing, can be formally put into production.
(11) a continuous acoustic inspection of weld mark the site, after manual ultrasonic and X ray review, if there are defects, after repair, again after testing, until the defects have been eliminated.
(12) strip butt weld and the intersection with the spiral seam D joint in the tube, all through X ray TV or film inspection.
(13) each pipe by hydrostatic pressure test, the radial sealing pressure. Test pressure and time by detecting pipe hydraulic device for strict control of microcomputer. Test parameters automatically print records.
(14) the pipe end machining, the end verticality, accurate control to get the slope angle and blunt edge.
