Large Diameter Steel Tubing Ssaw Tube Pressure Purposes 40 Inch
Spiral steel pipe is a steel strip coil plate of raw materials, often warm extrusion molding, with automatic double wire welding double-sided submerged arc welding technology with the spiral seam pipe.Spiral steel pipe will strip into welded pipe unit, the multichannel roll rolling, strip steel rolled up gradually, there is an open space form of round billet, adjust the quantity of the squeezing roller, make the weld gap control in 1 ~ 3 mm, and make joint flush on both ends.Large Diameter Steel Tubing Ssaw Tube Pressure Purposes 40 Inch water pipeline.
the raw material is steel strip coil, wire, flux.Have to pass
strict physical and chemical inspection before investment.
welding and welding are used within the United States Lincoln
welding machine for single or double wire submerged arc welding, to
obtain the stable welding quality.
after welding the weld passes the online continuous ultrasonic
automatic meter check, ensure the spiral weld nondestructive
testing coverage of 100%.If there are defects, automatic alarm and
spray tags, production workers to adjust process parameters, in a
timely manner to eliminate defects.by air plasma cutting machine to
cut the steel tube into single.
After cut into single pole (10), the head of every batch of steel
pipe should be strictly check system, check the weld mechanical
properties, chemical composition, amalgamation, steel tube surface
quality and the nondestructive flaw detection, ensure that
qualified pipe process, can be formally put into production.
