The strong point for seamless steel pipes

Compared with welded pipe, what is the strong point for seamless Steel Pipes? And what disadvantage do weld pipes have?

1.The greatest advantage of seamless steel pipes is their increased ability to withstand pressure. The weakest point in a welded Steel Pipe is the welded seam. But because a seamless steel pipe has not been welded, it doesn’t have that seam, making it equally strong around the entire circumference of the pipe.

2.Because welded pipe is wrapped around another form before it is welded, and because welding adds heat, stress and other extraneous variables to the forming process, it can never be as round as seamless steel pipe.

3.sometimes seamless pipes can  be more expensive than other forms of steel pipe, but it’s also more reliable than others.

This is because it has greater strength under loading. Empty pipe must always support its own weight, but when a pipe is filled with material–or under load–it must also support that weight as well. Pipe failures and leaks in welded pipes usually occur at the welded seam. But because Seamless Pipe doesn’t have that seam, it isn’t subject to those failures.
