Quality Assurance
The company's Quality Assurance Department ensures that fabrication and repair needs meet the latest code requirements of ASME and TEMA. QA also helps customers determine the repairs required to return equipment to service as quickly as possible, minimizing critical unit downtime.

Our Quality Assurance personnel are certified by the American Society of Non-Destructive Testing (ASNT) SNT-TC-1A, American Petroleum Institute (API) 510, and American Welding Society AWS - CWI - CWE and in accordance with those standards.

Digital photographs of work in progress is a QA activity that is greatly appreciated by our customers, especially those who are located many miles from our facilities. Office accommodations are provided to our customers, offering them safe, quiet, air-conditioned work spaces. Network connections are also provided for access to the Internet.
