Introduction Of Straight Seam Steel Pipe

Straight every pipe in English (Straightsteel pipe), general welded pipe: General welded pipe used to transport low-pressure fluid. With Q195, q215a, q235a Steel, q235b carbon production. can also be easily welded 0317 Standard Model 6012 and steel mother 755 soft steel joint manufacture. Steel pipe to carry out the water pressure, bending, flattening and other experiments, on the surface quality has a certain requirement, the usual delivery length of 4-10m, often required to set the ruler (or scale) delivery.

　　Welded pipe specifications with the nominal diameter (mm or inch) of the nominal diameter and the actual difference, welded pipe according to the provisions of the wall thickness there are ordinary steel pipe and thickening pipe two, pipe-end in the form of pipe and thread and without thread two. The welding process for submerged arc welded pipe is submerged arc welding technology, with filler welding and particle protection flux submerged arc. The production caliber can reach the 1500mm,lsaw is the English abbreviation of the submerged arc welded straight seam steel pipe, the production process of the submerged arc welded straight seam steel pipe has the jcoe forming technology, the coiled type submerged arc welding technology. When the caliber is larger, it is possible to use two steel plates for rolling, which will form the phenomenon of double welds. can be implemented standard gb/t3091-2008 low-pressure fluid steel pipe production standards, Gb/t9711.1-2-1997 oil and gas pipe production standards, but also the implementation of the U.S. API 5L pipeline pipe implementation standards. Production material: q195a-q345e;245r; q345qa-d; l245-l485; X42-x70. The main pressure parameters are 2st/t, S is yield strength and T is wall thickness. Now submerged arc welding has developed into, there are two-wire submerged arc welding, as well as multi-wire submerged arc welding, the efficiency of further improvement.
