Xifolong Valve Group Co., Ltd.

Xifolong is a manufacturing enterprise specializing in the design, research, development, production, sale and service of valves in the fields of Oil,natural gas transmission engineering, coal chemical industry, electric power, urban pipeline network, petrochemical industry, offshore platform, PTA, LNG, metallurgy and so on. Its products are well sold indomestic and overseas market.

Xifolong has established a technology research and Development Center, with more than *0 seniortechnical engineers. It introduces the most advanced engineering software such as Auto CAD, ANSYS and Solidworks, and uses its advanced finite element analysis function to simulate and verify the rationality, reliability and safety of its design before mass production of new products.

Xifolong has been committed tothe R & D, manufacturing and technical servicesinmedium and high-end valve products, and hasconstructed an advanced modern valve inspection and test center, which can carry out simulated working condition tests on valves: - **6„ƒ ultra-low temperature test, maximum **0MPa (****0psi) high-pressure gas test, **0„ƒ high-temperature test and - *0 ~ **0„ƒ high or lowtemperature cycle test (API 6A / *7D PR2‰, **0 „ƒ thermal pipe network valve thermal performance test, ***0m water depth underwater valve (subsea valve) external pressure test, torque test of the maximum *****0N.M, as well as desktop and mobile spectrum analyzer, three coordinate detector, helium mass spectrometer and other precision detection instruments›at the same time, Tat test can be carried out according toSHELL MESC specification to provide users with safe, reliable and long-life high-quality products.

With advanced and mature design and development ability, scientific and sophisticated  quality control system, strict internal control management, reliable production and inspection ability, national and international authoritative system certification and product certification, XFL valve has obtained ISO***1, ISO ****1,ISO ****1, TS (A1, A2,B.), TS (Manufacture of pressure vessel),API 6A,API 6D, PED / CE, API **7 / 6fa, SIL3, ISO ****8and other certifications, it provide reliable guarantee forHigh quality and high-end valve production.

Xifolong has established a production and manufacturing center, with various processing equipment, CNC machine tools and processing centers, *-meter heavy-duty CNC vertical lathe bearing *0 tons, **0 tons of large-scale CNC floor boring machine, several full-automatic ball valve welding machines,*0*0 tons of super large valve pressure testing machines, **0 tons of valve assembly machines, etc.,It provides a powerful guarantee for users toproduce high-quality valve products quickly.
