The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high-frequency inductor consisting of a metal coil with single or multiple windings.Welded vs. seamless steel pipe | American Piping ProductsWelded pipe starts out as a long, coiled ribbon of steel called a skelp. The skelp is cut to the desired length, resulting in a flat rectangular sheet. The width of that sheets shorter ends will become the pipes outside circumference, a value that can be used to calculate its eventual outside diameter.
