La description
Large-diameter welded pipe is the pipe welds, raw materials are
mainly steel sheet and strip, large diameter straight seam welded
steel pipe is used, the higher productivity of the kinds of steel,
more used in more low-cost steel products one. Large diameter
spiral welded steel pipe is used, compared to the straight pipe
joints, mechanical strength of the products is relatively high, to
save raw materials, but the production is slow. The product is
widely used in water engineering, petrochemical industry, chemical
industry, power industry, agricultural irrigation, urban
construction, is one of the products of China's *0 key development.
For the transport of liquids: water supply, drainage. For gas
transportation: gas, steam, LPG. For structural purposes: as piling
pipe for bridges; piers, roads, pipes and other building
structures.
In the large-diameter steel pipe welding process, the most commonly
used is welded steel pipe, which is mainly used for oil drilling
and machinery manufacturing stove pipe can be used as water-gas
pipe, large diameter welded pipe for high pressure gas
transmission, etc.; spiral welded pipe for oil and gas, piles,
piers, etc. seamless steel pipe and welded steel pipe is lower than
cost, high production efficiency. Longitudinal simple production
technology, high production efficiency, low cost, rapid
development. spiral strength than the straight seam welded pipe is
generally pipe, can narrow the billet production of large diameter
pipe, you can use the same width of the billet production of
different pipe diameters, but with a straight seam pipe compared to
the same length, the weld length of *0 to **0%. and lower
production rate, so the smaller diameter pipe is mostly a straight
seam welded, large diameter spiral welded pipe is mostly used.
According to different methods can be divided into arc welding
pipe, high or low frequency electric resistance welded pipe, gas
pipe, stove pipe, Bundy tubes. According weld shape can be divided
longitudinally and spirally welded pipe welded steel refers to
steel or steel bending round, square, etc. and then welded into
shape, the surface of the steel pipe seams welded steel pipe
production process simple, high production efficiency, variety
specifications, less capital equipment, but generally lower than
the intensity of seamless steel tubes. since the ***0s, along with
the rapid development of high-quality steel rolling production, and
improve the welding and inspection technology, continuous
improvement of weld quality, welded steel pipe increasing number of
varieties and specifications, and in more and more areas instead of
seamless pipe.
