High purity stainless steel tubing

Difference between High Purity and Ultra High Purity (UHP) Tubing

The High Purity Stainless Steel Seamless Tube must meet some stringent requirements of industries such as biotechnology, pharmaceuticals, food processing, and semiconductors. These SS 304 High Purity tubing solutions are produced following a strict process and they require environments which have controlled temperature and pressure. Usage of such a clean room has benefits like it reduces the particles released to the environment by the machining operations. Such practices help to ensure the highest cleanliness level and prevent the occurrence of any post-cleaning contamination.

The 316SS Ultra High Purity tubing is manufactured in a similar but stricter environment. They have higher purity levels and can be made using materials that have been rigorously tested for impurities. They are used in very critical industries like semiconductor manufacturing.
