Oil Pipeline API 5L PSL1 X42 Straight Seam Welded Pipe
The advantages and disadvantages of welded steel pipe
The average wall thickness of the tube light table table high (steel exterior appearance of steel grade resolution, brightness) can be arbitrary length. Thus, it showed its economy and aesthetics in accuracy, the use of low-pressure fluid.
Welded steel pipe production process is simple, high production efficiency, low cost, to carry out faster. Spiral Welded Longitudinal higher than normal, can narrow the billet production of large diameter pipe, you can use the differences diameter pipe billet production of the same width. What, then with the same length of straight pipe joints compared weld length add 30 to 100%, and lower production rate. Thus, most of the smaller diameter pipe straight seam welded, large diameter spiral welded pipe for the most.
Classification of welded steel pipe
1, High frequency welded steel pipe features: tubular good, uniform thickness, internal and external burrs produced by the welding tool calibrating the appropriate online through strict control of non-destructive testing of weld quality, high degree of automation, low production costs. But relatively thin wall thickness, diameter is relatively small, usually no more than a wall thickness of 12mm, diameter generally does not exceed 610mm, particularly suitable for the production of steel tube truss structure.
2, LSAW pipe features: welding under static conditions, high weld quality, short welds, the probability is very small defects. By expanding full-length steel tubular good, precise size, wide range of pipe wall thickness and diameter range, the diameter range up 406-1829mm, wall thickness range up 6.0-60mm, high degree of automation, Compared to seamless steel, it is lower production costs, for buildings, bridges, dams, offshore platforms and other steel bearing with columns, large span structures as well as wind and seismic requirements for electrical tower mast structure.
3, Spiral submerged arc welded pipe features: spiral weld line distribution, long welds, especially
