The welded steel pipe has won praises for its uniform wall thickness and low price. So, can seamless Steel Pipes be replaced by welded steel pipes? The answer: NO
There are some reasons
1) HAZ is very fragile
Although it is rare now that the mechanical properties of the weld seam exceed the base metal itself, the weakest part of the welded steel pipe is not the weld seam, not the base metal, but the heat-affected zone of the weld. This place is the most vulnerable.
