Seamless
stainless steel piping, or seamless steel pipe, is formed by drawing a
heated solid billet, or cylindrical bar of steel, over a piercing rod to create
a hollow shell. Rollers are then used to produce the proper diameter and wall
thickness. This type of stainless steel
piping can withstand pressure better than welded pipe because it does not
have any seams to create weak spots. It is often used in the chemical and
petroleum industries.
