High Purity Stainless Steel Process Piping: clean after installation or build clean?

By admin | Posted in Gas Delivery Systems FAQ |

In the past, the process of manufacturing metals would create a product that would not be suitable for high purity applications.   The old manufacturing process would require cleaning or flushing systems after installation, as well as testing & verification that the system was clean and ready for use.

With modern advancements such as electric furnaces and cleanrooms, stainless steels can be produced, formed, and packaged inside high grade cleanrooms, with virtually no contaminants such as total hydrocarbons (THC’s) or particulates. This allows installers and fabricators to utilize protocols to keep the materials clean throughout the process of installation.

It generally costs less to put in place these proper protocols in place to ensure that the system stays clean from un-packaging to initial startup of the system.  In fact, introducing cleaning agents or DI water can actually be more detrimental as they can be difficult to fully remove from a system, and they can lead to issues when purity analysis is performed during validation.

Building clean generally results in lower costs in the end as well as a lower risk of having issues with contamination in your system.
