Tube sizes & wall thickness
Specify stainless steel tubing by its outside diameter and wall thickness. Use these reference dimensions to start an enquiry, then confirm grade, length and service requirements.
Pressure & temperature selection
A tube size alone does not define a safe working pressure. Select tubing together with its material, wall thickness, temperature, fittings and the conditions of the complete system.
ASTM A269 & ASTM A213
Understand the specifications behind a tubing enquiry. A material grade, a manufacturing specification and an inspection certificate describe different aspects of the product.
Certification & traceability
Connect the tube in your installation to its material documentation. State the required inspection certificate and traceability package before placing an order.
Select, handle & prepare tubing
Good tubing selection continues through storage, cutting, bending and assembly. Protect the surface and follow the instructions for the exact connection system you use.
