The quality control for all the staff and the whole process have been strictly carried out in accordance with the system files and the TS requirements. They also implement technical researches and process validations for major technical and quality issues; for the key processes in production, quality control points have been designed to strengthen the prevention and control; three control processes are established for the strict quality inspection: incoming inspection, semi-finished inspection and finished products inspection; and the three-inspection system, with special inspection as the main task, supplemented by self-inspection and mutual inspection; the labels on semi-finished, finished products and substandard products in warehouses, at workshops, and on production lines should be distinctively identified, to ensure the traceability of product quality.
The company has physical and chemical labs and NDT rooms which can test carbon steel, alloy steel, austenitic stainless steel, duplex stainless steel, special steel and other materials. The NDT room is equipped with liquid penetration PT testing, magnetic particle MT flaw detection, RT-ray flaw detection, and ultrasonic UT flaw detection. It can also conduct NDT tests for valve bodies, welded parts, stems, springs and so on.
In order to ensure product quality and meet customer needs, we have been continuously deepening the internal management, and spending all efforts to improve the quality awareness of all staff, to wholeheartedly provide customers with quality products.
