DSAW (DOUBLE SUBMERGED ARC WELD)
Product Announcement from Tubacero S de RL de CV
Double Submerged Arc Welding is a process which applies an inner and outer seam to the pipe followed by a cold expansion process to enhance its dimensional characteristics. The pipe is then submitted to a hydrostatic test as well as visual and dimensional inspections according with the required specifications. DSAW is applied to pipes with an outside diameter of 18" or greater.
