What is the Difference Between Seamless Pipes & Welded

However, there is a restriction on the manufacturing of large diameter pipe. Seamless pipes are widely used in the manufacturing of pipe fittings such as bends, elbows, and tees. Normally, the weakest part of pipes is the welding line, but seamless pipe doesn’t have a seam, so the entire circumference of the pipe can evenly withstand high pressure.
