Stainless steel pressure tube FAQ

The size and thickness required are based on the pressure and temperature requirements, media being transported, and the system's specifications.
Tubes are often tested using non-destructive methods. The main approaches we take are eddy current testing and air underwater testing, to ensure there are no leaks or weak points of the welding bead.
Yes, these tubes can be bent or shaped, but this must be done carefully to avoid creating stress points that could compromise the tube's integrity.
Stainless steel is the preferred material for pressure tubes due to its exceptional corrosion resistance, high strength-to-weight ratio, and superior durability, enabling it to withstand high pressures and extreme temperatures. Its hygienic, non-porous surface is ideal for sanitary applications, while its aesthetic appeal and ease of maintenance add to its practicality. Moreover, stainless steel's excellent weldability allows for secure, custom fabrication, and its 100% recyclability underscores its environmental benefits. These attributes make stainless steel tubes a cost-effective and reliable solution for demanding pressure applications across various industries.
Regular maintenance includes visual inspections and cleaning with appropriate chemicals or solvents that do not damage the stainless steel. In some cases, passivation may be performed to enhance corrosion resistance.
Stainless steel is highly recyclable, reducing its environmental footprint. Its longevity also means less frequent replacement and reduced waste.
