Seamless steel 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.
