May 27, 2020 · Submerged arc welded straight seam steel pipe can be executed standard GB/T3091-2008 low pressure fluid steel pipe production standard, GB/T9711.1-2 -1997 oil and gas steel pipe production and use standard, can also implement the US API 5L pipeline steel pipe execution standard. Comparison Of Spiral Steel Pipe, Straight Seam Steel Pipe The production efficiency of straight seam pipe is high, the cost is low and the development is fast.The strength of spiral welded pipe is generally higher than that of straight welded pipe, and the main production process is submerged arc welding. Spiral steel pipe can be used to produce different pipe diameters with blank of the same width Comparison of spiral steel pipe, straight seam steel pipe Spiral steel pipe can produce welded pipes with different pipe diameters from the same width of blanks, and can also use narrower blanks to produce welded pipes with larger pipe diameters. However, compared with the straight seam pipe of the same length, the weld length is increased by 30-100%, and the production speed is lower.
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW). JCOE1420 large straight seam unit - yuantai-steelThe double-sided submerged arc welding large straight seam welded pipe can be directly used for oil and gas transportation. JCOE steel pipe was widely used in the national "West-to-East Gas Pipeline" project. At the same time, it can be used as a structural steel pipe in the construction of super high-rise steel structure projects. Straight Seam Submerged Arc Welded Pipe Is Widely UsedThe main materials of straight seam submerged arc welded pipe manufacturers are D36 steel, S355 steel and structural steel plates with Z-direction properties. The thickness is generally between 20 and 50 mm. Due to the large thickness of the plate, the carbon content and carbon equivalent are higher.
Straight Seam Welded Steel Pipe Weld Transverse Crack Reason Analysis. First pre-welded straight seam submerged arc welded pipe, then the welding, and finally outside welding.

ERW steel pipe weld defects only wire-line and straight welds, the inspection process easy to follow, and the defects in the maximum reflection at, once the lack of implicit, ultrasonic reflecting the strong, easy to detect. ERW steel pipe related to saw steel pipe in residual stress ratio is low. Submerged arc welding spiral steel pipeThe production process of submerged arc welding spiral steel pipe:It is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process with strip steel coil as raw material, often extruded and formed at temperature.ubmerged arc welding spiral steel pipe:It is a spiral seam steel pipe welded by automatic double Welding advantages of double submerged arc welded straight Welding advantages of double submerged arc welded straight seam steel pipe. Double submerged arc welded straight seam steel pipe is a new welding method invented in 1940, it is the same place and the front of the manual welding it or slag protection, but this residue is not the electrode coating, but melting out welding flux.
Jan 14, 2020 · The straight seam steel pipe in Hebei often refers to the double-sided submerged arc straight seam steel pipe produced by JCOE, which adopts the JCOE cold forming process. The welding seam uses welding wire and the particle flux is used for submerged arc. What is a LSAW steel pipe? ASTM A234 butt weld pipe LSAW steel pipe (Longitudinally submerged arc welding steel pipe) in leaflets plate as raw material,the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.A wide range of the finished product specifications, weld toughness, ductility, uniformity and dense, with a large diameter, wall thickness, high pressure straight seam welded steel pipe tubeThe Difference Between the Straight Seam Welded - East Steel Pipe. Mar 26, 2015 Straight seam welded pipe is made of steel plate or steel strip after oxygen blowing metric welded pipe, welded pipe, wire casing, roller tube, Difference between lsaw and erw steel pipe - HYSP Steel Pipe . The double-sided submerged arc welding straight seam
(3) For pipes with high requirements for internal and external anti-corrosion coatings, straight seam submerged arc welded steel pipes shall be used. Spiral submerged arc welded steel pipe has many weld beads. The weld bead height is generally higher than that of straight seam submerged arc welded steel pipe. When the inner and outer anticorrosion of the steel pipe is carried out, the combination of anticorrosive material and bare pipe is not as tight as that of straight seam submerged
