Seamless steel pipes are manufactured from solid round billets which are pierced through the middle with a mandrel. The billet is rolled and stretched through the hollow billet until it meets the customer's requirements. Because of its uniform shape and ability to withstand pressure and heat, seamless steel pipe is an ideal material for many industries. Fittings offers a wide variety of seamless steel tubes to meet your application needs, offering a large selection of sizes and lengths. Benefits of Seamless Steel Pipe Seamless steel tubes offer a variety of benefits, depending on your application. They perform well in harsh conditions, which means they can be used in extremely cold or hot conditions. Because of these benefits, seamless steel pipe is the material of choice for a range of commercial piping applications. Other benefits of seamless steel pipe include. Ability to withstand high levels of pressure Uniform shape Reliable strength under load Applications for Seamless Pressure Tubing Seamless steel tubing is often a good solution for applications with high temperature, high pressure or corrosive materials. Seamless steel tubing can be used in a variety of applications, including. Heat exchangers Chemical and petrochemical industries Power generation and environmental technology Shipbuilding/Shipbuilding Oil and gas applications Pressure Applications Seamless Tubing and Seamless Pipe Selection Whether you need seamless or seamless pipe depends on your intended application. Seamless tubing is typically used for structural applications. Therefore, the outside diameter and wall thickness are important and need to be within very close tolerances. Seamless steel pipe, on the other hand, is typically used for the transport of gases or fluids in piping systems. Seamless steel pipe is measured using the nominal outside diameter and wall thickness, rather than exact outside diameter and wall thickness. The nominal OD is a standardized measurement that does not change if the wall thickness changes.
