Is seamless pipe stronger than welded?
Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So
it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding
seam of the welded steel pipe is the weak point, the quality affect overall performance.
How do I know if my pipe is ERW or seamless?
The main difference between seamless and erw pipe is that a seamless pipe is produced without the help
of welds or seams, however, erw pipes are manufactured by welding pieces of steel longitudinally. What is
erw pipe? An erw or electric resistance welded pipe is welded with the help of coils and strips of steel.
What does AISI 304 stand for?
American Iron and Steel Institute
AISI stands for American Iron and Steel Institute. Therefore, both grade 304 stainless steel and grade
316 conform to the American standard. The European equivalents are 1.4301 and 1.4401, respectively.
