Material traceability is critical in today’s valve manufacturing industry. It is also critical to after-market valve modifications or repairs. United Valve utilizes two Niton XRF analyzers to confirm that every piece of pressure containing raw material or critical component is exactly as specified. No critical piece of raw material is released for production without first receiving a positive material identification (PMI).
In addition to daily in-house quality control duties, our PMI machines are used to complete purchase order requirements. Personnel have been trained to perform examinations in accordance with API RP578.
