SINCE 1958

Xi'an Pump & Valve Plant Co .,Ltd

Xi'an Pump & Valve Plant Co .,Ltd was founded in 1958, formerly known as Xi'an High Pressure Valve Factory. It is a modern scientific and technological enterprise integrating research and development, design, manufacturing, sales and technical services of special pumps and valves. Products are widely used in acetic acid, MMA, PTA, caustic soda, polyester, water treatment, coal chemical industry, oil and gas, new energy and other industries.

With the mission of "scientific and technological innovation and industry serving the country", Xi'an pump valve has been deeply integrated with Zhejiang University, Xi'an Jiaotong University and Northwestern Polytechnical University in the field of scientific research, and has built Xi'an pump valve-Xi'an Jiaotong University Technology Research Institute.

Major breakthroughs have been made in the casting and performance improvement of titanium-zirconium materials, surface hardening treatment of titanium-zirconium materials, corrosion mechanism and protection of titanium-based materials in marine environment, multiphase flow transportation, hydraulic design and optimization of high cavitation resistance of centrifugal pumps, flow field analysis and structural optimization of high-pressure melt filters, etc., with independent intellectual property rights and engineering applications.

The company is a high-tech enterprise with more than 110 independent intellectual property rights, including more than 20 invention patents, 5 national standards and 6 industry standards. The company has ISO9001, API6A, API6D, CE, SIL and other key certificates and A2 fixed pressure vessel design and manufacturing certificate.

The company has a special material vacuum casting production line in the pump and valve industry, which can realize independent production from sponge titanium (zirconium) to castings. The weight of single castings can reach 1500kg, and the annual production capacity can reach more than 500 tons. The products are exported to Japan, Finland, Russia, Iran, India and other countries.

The company has many advanced four-axis and five-axis machining centers, gantry three-dimensional coordinate measuring instruments, professional non-destructive testing equipment and physical and chemical laboratories. It has DN1400 large insulated joint pressing machine and bending moment test bench. It has plug valve clamping sleeve pressing system with specifications up to NPS 24 600Lb; It has advanced special material surface hardening equipment. It has a domestic gas-liquid two-phase flow testing center with a medium gas content of 50%; built a valve cryogenic test center and melt filter high temperature and high pressure test system. These advanced processing and testing equipment provide a strong guarantee for the development and manufacture of high-quality pump and valve products.

The company has provided zirconium mother liquor circulating pump, zirconium external circulating pump, titanium dechlorination vacuum pump, zirconium gas-liquid two-phase flow pump, titanium alloy hard seal ball valve, zirconium screw plug valve, insulated joint and other "products" in Jiangsu Jiatong 3 million tons PTA, Hualu Hengsheng 800000 tons acetic acid, Shaanxi Jintai 600000 tons caustic soda, Qingmeibang 150000 tons wet smelting Indonesia project, Jiangsu Sirbang 90000 tons MMA, Sino gas pipeline (DN1400) and China, steady leading position in the domestic market. The company also has titanium axial flow pump, urea melt pump, multi-stage pump, automatic recirculation control valve (return valve), melt filter and melt valve, wellhead skid-mounted equipment, ultra-low temperature ball valve, special material regulating valve and other products, widely used in chemical and oil and gas industries.

Heart service, the achievement of the future. Xi'an pump valve people adhere to the values of "unity, hard work, dedication and diligence", adhere to the business philosophy of "customer first", wholeheartedly provide customers with high-quality products and services, share win-win results with customers, and create a better future!
