Large-diameter Welded Steel Pipe

Large diameter steel pipe exterior diameter 100MM more than the wall thickness is greater than the outer diameter of the pipe, massive diameter seamless steel ingot zero.2 or perforated tube made of strong capillary, and then by hot-rolled, chilly-rolled or chilly-name system percent.

Massive-diameter welded steel pipe is the pipe welds, uncooked materials are primarily steel sheet and strip, large diameter straight seam welded steel pipe is used, the upper productivity of the kinds of steel, more used in more low-price steel merchandise one. Large diameter spiral welded steel pipe is used, in natural resources coal and petroleum comparison with the straight pipe joints, mechanical energy of the merchandise is relatively excessive, to save uncooked materials, but the production is gradual. The product is extensively utilized in water engineering, petrochemical industry, chemical trade, energy industry, agricultural irrigation, urban building, is among the merchandise of China’s 20 key growth. For the transport of liquids: water supply, drainage. For fuel transportation: fuel, steam, LPG. For structural purposes: as piling pipe for bridges; piers, roads, pipes and different constructing constructions.
In the big-diameter steel pipe welding process, the mostly used is welded steel pipe, which is primarily used for oil drilling and machinery manufacturing stove pipe can be utilized as water-gas pipe, large diameter welded pipe for top strain fuel transmission, etc.; spiral welded pipe for oil and gasoline, piles, piers, etc. seamless steel pipe and welded steel pipe is decrease than value, excessive production efficiency. Longitudinal simple production technology, high manufacturing efficiency, low cost, rapid development. spiral power than the straight seam welded pipe is mostly pipe, can narrow the billet manufacturing of giant diameter pipe, you can use the same width of the billet manufacturing of various pipe diameters, but with a straight seam pipe compared to the same size, the weld length of 30 to 100%. and decrease production rate, natural resources coal and petroleum so the smaller diameter pipe is generally a straight seam welded, giant diameter spiral welded pipe is generally used.
Based on completely different strategies may be divided into arc welding pipe, high or low frequency electric resistance welded pipe, fuel pipe, stove pipe, Bundy tubes. According weld shape will be divided longitudinally and spirally welded pipe welded steel refers to steel or steel bending spherical, square, etc. and then welded into form, the surface natural resources coal and petroleum of the steel pipe seams welded steel pipe manufacturing process simple, high manufacturing efficiency, variety specifications, much less capital tools, but generally decrease than the intensity of seamless steel tubes. for the reason that 1930s, together with the rapid improvement of high-high quality steel rolling manufacturing, and improve the welding and inspection expertise, continuous improvement of weld high quality, welded steel pipe increasing number of varieties and specs, and in increasingly more areas instead of seamless pipe.
