Three Key Advantages

Selected Around Pressure-Service Conditions

Material grade and tube dimensions are selected from the actual pressure-service conditions, process medium and applicable standard.

Wall Thickness as a Design Parameter

Wall thickness is considered together with tube diameter and operating conditions rather than treating a heavier wall as automatically more suitable.

Testing and Documentation Defined Up Front

Required testing, material certificates and acceptance documents are clarified before ordering so the inspection scope is clear from the beginning.

FAQ

Q: Is working pressure enough for you to quote the tube?

A: No. We also need the material grade, tube size, wall thickness, standard and other relevant design information. Working pressure alone does not define the tube specification.

Q: Can additional testing be added to the order?

A: Yes, if required by the standard or your project. Tell us what testing is needed before ordering so we can check it together with the material specification.

Q: When should I tell you which inspection documents I need?

A: Ideally, at the inquiry or order stage. If specific certificates or test reports are required for project acceptance, it is better to have them written into the order from the beginning.
