During the production stage, all machined components are being checked for accuracy. Random checks are performed on the running production. Results from all relevant measurements get recorded by quality inspection workers. After evaluation of all results recorded, long term actions are suggested by our professionals. This approach enables us to achieve continuous improvement in our production process.

Oilway quality standards require that every single piece of valve passes a tightness test performed by assembly line operators and randomly checked by independent quality workers. Tightness tests are performed under standard conditions acc. comply with API 598, EN 12266 and GOST R.

Final quality inspection is performed after complete valves are handed over from the assembly line but before they are made available for expedition by the packaging and storage department. During the final inspection process, finished valves are inspected for conformity with customer requirements. This check is performed by auditors who are independent the production department, and only after conformity is confirmed, valves are released for expedition.
