SEAMLESS TUBE

The homogeneous nature of seamless stainless steel tubing
makes it stronger, superior to corrosion resistance, and higher pressure resistant. These precision manufactured tubes are cold finished to tight dimensional tolerances to meet exacting engineering requirements.
Key markets for seamless tubing include: Alternative fuels, Chemical and petrochemical industries, Marine applications, Mechanical and plant construction, Oil and gas applications, Power generation.

Industry Applications
