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.

Ded at the option of the manufacturer. Main steel tube grade: a53-a, a53-b etc. Other grade can also be provided after consulting with acustomers. Permissible variations in weight and dimensions: Weight -- the weight of the pipe as calculated from the relevant equation in asme b36.10m shall not vary by more than 10%. Diameter -- for pipe nps 1 1/2(dn40) and under, the outside diameter at any point shall not vary more than 1/64 in.(0.4mm) from the standard specified. For pipe nps 2 (dn 50) and over, the outside diamter shall not vary more than 1% from the standard specified. Thickness -- the minimum wall thickness at any point shall not more than 12.5% under the nominal wall thickness specified. The minimum wall thickness on inspection shall comform to the requirement. - According to astm a700
