Technical specifications

CSM Tube can manufacture stainless steel tubing to the technical specifications and sizes required by clients. Our team have years of experience in delivering the right properties for different applications, along with specific diameters or wall thicknesses.

Customers requiring standard stainless steel tubing can specify diameters and wall thicknesses, maximum camber and the inside weld bead, as well as lengths that suit their needs. Lengths can vary from 300mm to 14,000mm, while diameters range from 4-28mm.

Heat-treated steel tubing is also available. In this case, the standard hardness is 160HV5, although this can be changed on request. If customers need to adhere to the ASTM A-249 welded steel pipes specification, we deliver a standard hardness of 90HRB. Coil lengths can be customised as well, while all heat-treated tubing is pressure tested in accordance with EN 10217-7 standards.

Our piping can be ordered in inox, AISI 300/400 series and high nickel content alloys (800 - 825 – 840 and 600 - 601). In all cases, technical specifications are included to ensure 100% traceability.
