The company spirit of "customer first, integrity-based" business philosophy, put forward the "based on quality, strengthen management, continuous improvement, customer first" quality policy.


Attach importance to the product quality and demand of each customer (or project), set up a project team, make overall arrangements for design, manufacturing, inspection and other work, to ensure the quality, quantity and timely delivery of products.


It attaches great importance to the selection of talents, training, incentive and performance evaluation, and is a hot land for first-class professionals to gather together. Create a good environment for the growth of talents, so that every capable and enterprising staff can display their talents and realize their ambitions.

In accordance with ISO9001:2008 "Quality Management System Requirements" and "Special Equipment Manufacturing License" requirements, the company has established a strict quality control system, control links, control points, all personnel, the whole process of quality control has been strictly in accordance with the system documents and TS requirements of organization and management, serious implementation. Conduct technical research and process verification for major technical problems and quality problems; Quality control points are designed for key processes in production to strengthen prevention and control. The quality inspection system shall be established to strictly control the three levels: incoming inspection, semi-finished product inspection and finished product inspection, etc., and implement the three-inspection system of focusing on special inspection, self-inspection and mutual inspection. Warehouse, workshop, production line semi-finished products, finished products and unqualified products clearly marked, so that product quality has traceability.

The company has a physical and chemical room, non-destructive testing room. Can test carbon steel, alloy steel, austenitic stainless steel, duplex stainless steel, special steel and other materials. Non-destructive testing room has liquid penetration PT testing, magnetic powder MT testing, ray RT testing, ultrasonic UT testing. Nondestructive testing of valve body, welding parts, stem, spring, etc.

In order to ensure product quality and meet customer requirements, we insist on deepening the internal management, strive to improve the quality awareness of all staff, dedicated to provide customers with quality products.

The company's existing plant covers an area of 13,000 square meters, building area of 14,700 square meters.

200 sets/set of all kinds of mechanical processing equipment (including a processing center equipment), 23 sets/set of testing equipment (including the safety valve delivery test bench). A safety valve full performance test device, the device can achieve the maximum caliber DN200/8 ", the maximum pressure of 10MPa/600Lb. At the same time, it has magnetic particle detection, Enos spectrometer, universal testing machine, carbon and sulfur analyzer, ultrasonic flaw detector, X-ray flaw detector, spring tensile testing machine, helium mass spectrum leak detector and other material inspection equipment.

Existing production of safety valve products of 172 employees, technical personnel 29 people, (including senior 1, intermediate 6 people).

Safety valve products are divided into "American standard series" , "national standard series" two categories and "American standard series breathing valve" .

"American standard series" Safety valves are designed, manufactured and inspected in accordance with the standards of API520, ASME I, ASME VIII, API526 and API527.
