Welded tubular products play a vital role in virtually every industrial segment supporting our daily lives. Stainless Steel Pipe Grades Corrosion Resistance have good to excellent corrosion resistance and high quality surface finish characteristics, and are for these reasons used in demanding applications such as food processing and pharmaceutical production, for the conveyance and processing of liquids, gases and semi-solids in solution.

A tighter tolerance can be agreed at the time of enquiry and order on tubes of < 114.3 mm of ± 0.5 % or ± 0.15 mm whichever is the greater.

Wall Thickness

For all tube sizes tolerance on wall thickness is ± 10 % or ± 0.2 mm whichever is the greater.
