Chengdu Singoly Cryogenic Technology Co., Ltd. was established in April of 2008, and is a cryogenic field science and technology type joint-stock enterprise which is specialized in design, manufacturing, sales and technical consulting services of natural gas liquefaction complete sets equipment and cryogenic equipment pressure piping components. The company is equipped with staffs who had obtained two national patents, and double eccentric flat butterfly valves and four-link butterfly valve level which achieves switching service life of more than 1 million times without leakage through unique friction-free structure, cryogenic storage valve R and D staffs who had obtain twelve national patents, and carried out major innovation on the basis of absorbing U.S. and Japanese technology; adept manufacture staffs who have mature design experience to secure attachment (cryogenic safety valve and cryogenic emergency shut-off valve), and completely achieve regulations to safety attachment demand in Chinese "Supervision Regulation on safety Technology for Transportable Pressure Vessel" and "Supervision Regulation on Safety Technology for Stationary Pressure Vessel", and professional management staffs who had produced and manufactured LNG cryogenic special-purpose valves according to API standards and PED regulatory requirements in R & D personnel. The company is provided with equipped manufacture equipment, welding equipment, cryogenic and corresponding detection equipment and other first-class production and test equipment, and advanced CAD design center. Valve categories which are specially designed and manufactured by our company include: butterfly valve, Diaphragm Control Valve, ball valve, globe valve, throttle valve, check valve, pressure reducing valve, safety valve, instrument valve, breathing valve, tee-switching valve and the like. Nominal diameter is up to 1600mm, the maximum pressure is 42MPa, the lowest used temperature is -269 °C, the highest temperature is +850 °C, and the valves are provided with manual, pneumatic, electrical and other transmission methods. They are mainly used in air separation equipment, petroleum, natural gas liquefied separation equipment, chemical tail gas separation equipment, liquid oxygen, nitrogen, argon, hydrogen, carbon dioxide cryogenic storage tanks and tankers, pressure-changing absorption oxygen and nitrogen preparation and hydrogen recovery equipment, ethylene high temperature cracker, power plants and other industries.
