The quality control of valve manufacturing starts from raw materials to the raw materials and quality insurance policies provided by qualified suppliers, 100% inspection, chemical composition and physical properties can be put into production, manufacturing process, strict implementation of DNV (Norwegian Classification Society) certification, ISO 9001:2008 quality management system control requirements.
The entire manufacturing and assembly process is controlled, including special processes such as heat treatment, welding and flaw detection.
Our quality Assurance department has all the data that has been certified by the customer or the designated testing authority. All tests including pressure tests, physical and chemical properties tests and flaw detection tests are analyzed to make them specific.
The entire process of product manufacturing strictly follows the company's quality assurance manual. We build a strict quality assurance network, every process is completed under the supervision of work instructions and quality controllers, and leave a trusted record. A formal audit system composed of corporate and customer review panels ensures process improvement and upgrading.
