Quality system

In order to standardize the establishment and implement the company’s pressure vessel quality assurance system and authentically ensure the effective control of the safety and energy-saving performance of pressure vessels, Pressure Vessel Quality Assurance Manual is worked out in accordance with the regulations of TSG Z0004-2007 Basic Requirements for Special Equipment Quality Assurance System on Manufacture, Installation, Alteration and Repair and based on the factory’s actual condition, e.g. its type of industry, scale and product structure, our design and manufacture quality assurance system has been established, improved and operating in good condition.

Inspection & testing


The pressure vessel was made by our company. is known for its stability, endurance and perfect features. In the fabrication line, every sequence will be strictly checked, including chemical analysis, physical features, anti-corrosion detection, metallurgical analysis and quantity-oriented spectrum analysis and others. In terms of NDE capability, test machine includes large-power Cobalt60 Gamma Radiography, X-ray machine, 4Mev liner accelerator with maximum scanning thickness of 250mm,RT,UT, MT and PT. These equipments and scientific quality management system make sure that the company can accomplish super large-scale core products for many critical projects.
