Seamless stainless steel pipe is used where high temperature strength and superior corrosion resistance is needed. For an overview of product offerings view our stainless steel products line card. We have a large selection of seamless pipe sizes and weights to choose from. The chart includes seamless pipe sizes, nominal pipe size (NPS) and pipe schedules to assist in your selection and help guide you to our in stock seamless pipe products. We have a variety of stainless steel seamless pipe and alloy seamless ASTM A312 pipe. View the standard specifications chart. View and analyze various stainless steel grades of seamless pipe and other products offered from Shaw Stainless. We developed a Reference Catalog for ease in identifying the many different stainless steel and other alloy products we offer. This catalog identifies stainless steel seamless pipe and other pipe products such as pipe fittings, accessories, etc. The catalog includes specification charts and illustrations to help in identification of inventory. Here is a chart to review theoretical bursting pressures for various stainless steel pipe. Stainless steel seamless pipe is manufactured from a solid billet and machining the center and the outside of the billet, to form a pipe to standard specifications. This process does not include any welding and because of this, seamless pipe was historically looked upon as being able to withstand pressure better than welded pipe. Seamless pipe was also more readily available in the past. Welded pipe has advanced with technologies, which has allowed a leveling of functionality and availability. Seamless pipe cannot be manufactured with small wall thicknesses, but if you are in need of stainless steel pipe with small to medium outside diameters and larger wall thicknesses, seamless pipe is the way to go.
