    Double Submerged arc welded pipe, DSAW pipe

    image001


    Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral  welded formats and used in a variety of applications. The submerged welding  process protects the steel from contamination of impurities in the air.

    Both inside  and outside welds are performed.

    *Difference between ERW and DSAW pipes

    *Difference between HFW and DSAW

    *Spiral double welding pipe process

    *Welding advantages of double submerged arc welded straight seam steel pipe


    DSAW pipe can be specified in very large diameter and to exact inside or outside dimensions. Spiral Welded steel pipe is distinguished by the manufacturing process that  results in a spiral DSAW seam the length of the pipe to lengths of 155 feet.

    The manufacturing of Double Submerged Arc Welded Pipe involves first forming steel plates into cylindrical shapes. Then the edges of the rolled plate are formed so that V-shaped grooves are formed on the interior and exterior surfaces at  the location of the seam. The pipe seam would then be welded by a single pass of an arc welder on the interior and exterior surfaces. The welding arc is submerged under flux. What can be known as an advantage of this process is that welds would penetrate 100% of the pipe wall and produce a very strong bond of the pipe.

    Full Supply Ltd have been supplying EFW Electric Fusion Welded Pipe for many years.


    We supply DSAW Pipe to the folowing industries on a global scale:

    *Oil Industry

    *Gas Industry

    *Filtration Industry

    *Refrigeration Industry

    *Refining Industry

    *Petrochemical Industry

    *Offshore Industry
