Exceptional standards

Our austenitic sanitary tubes and fittings meet the exacting standards and conform to ISO 9001-2015 manufacturing and quality standards.

Plus, all contact parts are manufactured from T316L quality materials. Sulphur is controlled at weld points to a 0.005% minimum and a 0.017% maximum to ensure high-quality orbital welds. 

Comprehensive traceability

As part of our Quality Control, we check that all raw materials purchased conform to the Chemical Analysis stated on the Material Certificate. All materials are also traceable back to the original Material Certificates, to ensure full traceability.

A wide variety of product options

Our extensive product range covers imperial sizes from 1/4” O.D. to 6” O.D. and metric sizes from 4mm to 8mm. This covers sanitary tubing, weld end fittings suitable for orbital welding and clamp ended fittings. The tolerances on our weld ended products are suitable for closed head orbital welding, with tolerances on squareness and wall thickness. Whichever product you choose, you can look forward to a choice of finish — mechanical or electropolished on the internal diameter, and mill finished or satin polished on the outer diameter. 

Professional packaging and certification

With your products carefully finished, they will be packed with all tubes and fittings supplied with ends capped and bagged. 

Your products will arrive accompanied by full material certificates, either with the goods or via email, or both if required. Where needed, we will provide a full quality dossier to cover project work.
