Comparison of Welding Technology Between Straight Seam Welded Pipe and Spiral Welded Pipe

The material produced by the spiral welded pipe( SSAW steel pipe ) is a hot rolled coil, and the straight welded pipe is made of steel plate. The amount of alloy contained in the coil is less than that of the steel sheet. For this reason, the spiral welded pipe has higher weldability than the stee ...
