Seamless pipes

Seamless carbon steel pipes are pipes without any weld . A solid billet is simply heated and then stretched over a series of mandrels until the pipe has achieved its desired diameter and wall thickness. Typically seamless carbon steel pipe fourteen inches and greater in diameter are rolled from shells which expand the diameter and reduce the wall thickness till the dimensions are achieved. Sizes smaller than fourteen inches in diameter are stretch reduced whereby the diameter is gradually reduced and the wall thickness relatively increased via a series of rolls. There is also a cold forming process for seamless pipe production, but manufacturing of such processes are typically reserved for different alloys. Being that there is no seam, seamless carbon steel pipe is typically used in high pressure applications. Common seamless specs include API5LB, A106, A333.
