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
