What is Seamless & ERW PIPES ? - What is the Difference between Seamless Vs ERW Pipe

About Seamless & ERW Pipes
1- Seamless Pipe
A seamless pipe is a tube that does not have any welding seam. Seamless pipes are derived from solid steel that is in sheet or bar form and is formed into a solid round shape known as “billets” which are then heated and cast over a form such as a piercing rod to create a hollow tube or shell
2- ERW Pipes
The erw pipe meaning was always shadowed by the fact that experts in the past stated that they are weaker pipes in comparison to seamless pipes. They are cold rolled after the hot rolling procedures giving the erw pipe superior corrosion and oxidation resistance properties
