Matching with suitable welding wires (H08C,H08MnA,H10Mn2,H08MnMoA,H08Mn2MoA),it can weld many kinds of steel pipes,such as X52,X60,X65,X70,X 8 0,etc.It also can be used in 16Mn,Q345C etc structural steel submerged arc welding. (4)Chemical Composition(%)
Fatigue Testing of Pipeline Welds and Heat-Affected from the X52 vintage pipe and the X70A pipe. Only the girth welds and their associated HAZs were tested from the X52 modern pipe and the X70B pipe. This information is shown in Table 2, along with the techniques used to construct the weld (SMAW= shielded metal arc welding, GMAW = gas metal arc welding, and SAW = submerged arc welding).
LSAW Steel Pipe, Longitudinally Submerged Arc Welding PipeUtilizes the "JCO" process to bend and form the crimped steel plate into a steel pipe. Interior welding machine The interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged-arc welding process.
LSAW Pipe is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.
Longitudinal Submerged Arc Welded Pipe LSAW Pipe Scope of Longitudinal Submerged-Arc Welded Pipe. Outside diameter:from 16 in (406.4 mm) to 60 in (1524.0 mm). Wall thickness from 6.0mm to 40.0mm. Length:3m 15m; LSAW Pipe Steel Grade. Common Class:API 5L Gr.B PSL1, PSL2, Sour Service pipe; Grade Medium:X42, X46, X52; Medium and High:X56; Grade High Level:API 5L X60 PSL1, PSL2 LSAW
Longitudinally Submerged Arc Welded Steel pipes, LSAW Mainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber, long-distance pipelines for oil and gas a small number, the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW), spiral submerged arc welded pipe (SSAW), LSAW steel pipe (LSAW) three.
