What is Ultra high purity stainless steel tubing?

The ultra high purity tubes are made of stainless steel and have higher purity degree than than standard high purity tubes. The Ultra High Purity Stainless Steel Tubing possesses good cleanliness and has good smoothness in its inner surface. One of the most popular materials used for these tubes is 316L. The UHP Tubing is made to meet the ever-rising demands of high purity systems in industries like biotechnology, semiconductor manufacturing, food processing and pharmaceutical production.

The Ultrahigh-Purity SS Tubes show good resistance to corrosion, and they are made with superior engineering techniques. They have precise fabrication and are manufactured in a superior quality controlled environment. Both the High Purity Stainless Steel Tubing and UHP stainless steel tubings are used in applications where high performance along with high cleanliness and purity is a major requirement.

They are typically used in high purity liquid or gas conveyors, clean gas supply construction, size exclusion chromatography, reverse phase chromatography, pharmaceutical instrumentation, and so on. You should contact a reputed supplier to get UHP tubes that are precisely engineered and comes with high quality control measures.

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.
