The difference between seamless and welded (as it is commonly known) pipes is the welded joint along the longitudinal direction. Seamless pipes are manufactured by continuous extrusion process. Seamless pipes have greater bursting and tensile strength than the welded ones.

Difference between seamless and erw pipe?
ERW (Electric Resistance Welding) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; hence ERW pipe has a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
What is the difference between seamless and non-seamless pipes?
Non-seemless pipe is rolled from a flat piece of metal and welded lengthways to form the piping. Seemless pipe is extruded and has no seems and is generally stronger.
What is the difference between seamless and welded pipe fittings?
Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless pipe withstands pressure better than other types, and is often more easily available than welded pipe.Welded pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible.
What mean smls pipe?
Seamless pipe
What is the difference between hot finish seamless pipe and cold drawn seamless pipe?
A cold drawn seamless pipe has better dimensional tolerance, a higher surface finish and better mechanical properties than an equivalent hot finish seamless pipe. For applications that can make use of the thinner pipe walls and closer tolerances, a cold drawn seamless pipe is the better option.
What is the difference between seam and seamless pipe?
seam less pipes are having with out weld but produced by extension process it is costly than seam

The pipe which is formed by seam welding.
What are the differences between black seamless pipe and black carbon steel seamless pipe?

What is meaning of 'efsw' in pipe?
Electro fusion seam welded pipe. I have found it on yahoo answers. If i'm wrong please reply with the right answer.
Why call seamless pipe?
Most pipes are made by taking a strip of metal, rolling it up and then fusing the seam together. They're almost always weaker along the seam than anywhere else. There are ways of making pipes where the wall is a single piece that hasn't been welded shut. They're stronger , more expensive and they're called seamless.
Difference between ERW and Seamless pipes grades?
One pipe is electric resistance welded (erw) the other is extruded through a thimble. In other words one has a seam the other doesn't.
