In SAW (submerged arc weld) welding process, external filler metal (wire electrodes) are used to join the formed plates. SAW pipes can have a single longitudinal seam and double longitudinal seams, it depends on pipe size, this is longitudinal submerged arc weld (LSAW). SAW pipe are also available in the spiral seam, which is continually rolled from the single plate coil, this is spiral submerged arc weld (SSAW). The production rate of spiral SAW pipe is very high as compared to Straight SAW pipe. However, Spiral SAW pipe are only used in low-pressure services such as water, non-critical process services etc.
Our company introduce advanced JCOE production equipment, specializing in the production of thick-walled large-diameter straight seam double submerged arc weld pipe products with a diameter of 406.4mm-1422.4mm, length 3m-12m, wall thickness 8mm-60mm, can be used for manufacturing oil and gas transmission pipe, piling steel pipe bracket pipe, the bridge steel pipe, various exhibition center truss steel.
