SAW pipe

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.
