In 1976, SASPG was appointed by the China central government to research and develop the turbo-expander unit for natural gas liquefaction and separation plants. Integrating the advanced technology introduced from abroad in China's 8th Five-Year Plan period and the experiences acquired within 40 years of manufacturing, SASPG manufactures the best turbo-expanders in China, which feature higher expansion ratio, more enthalpy drop, more liquid content in expanded gas and higher efficiency. The expanders have been exported to many countries such as the Philippines, Syria, India, Myanmar and Turkey.

ASPG supplies the booster turbo-expanders in the air separation plants with the capacity of 1000Nm3/h~100,000Nm3/h, in the gas liquefaction plants with the capacity up to 500 T/d and in the natural gas (associated gas) liquefaction & separation plants with the capacity up to 10 million Nm3/d and the inlet pressure up to 10.0 MPa. Almost all the turbo-expanders used in all the large oil fields are supplied by SASPG. In recent years, SASPG has developed this type of natural gas (air) pressure power generation expander and all liquid expander, of which natural gas (air) pressure power generation expander’s generating capacity is up to 4000KW and has been used in industry.

Situated in the affluent city of Jianyang, SASPG covers an area of 800000m2 with a floor space up to more than 300000m2.

Since its founding in 1966, the company has kept on increasing its operation scales and in 2014, the annual production capacity reached 50000 tons. Through many years of development, the company has acquired strong investment capability and has already established a number of entities. Currently, the company has 17 holding companies and 7 share holding companies.

As one of the large-sized manufacturers in China, a pivotal enterprise in China's machinery industry, one of the cryogenic equipment design and fabrication bases and also one of the backbone enterprises in Sichuan Provincial critical equipment fabrication industry, SASPG is mainly engaged in the design, fabrication, marketing of large, medium and small air separation plants, cryogenic liquid (cryogenic liquid oxygen, nitrogen, argon, liquid carbon dioxide, ethylene, LNG and liquid hydrogen) tanks, trailers, ISO tanks and vaporizers, super insulated cylinders, vacuum pipes, natural gas (associated gases) liquefaction and separation plants, cryogenic pumps, medium and small-sized piston compressor, cryogenic values and ambient-temperature valves, special valves and medical oxygen central supply system, medical central suction system, purified operation theatres, dissolved acetylene and environmental protection equipment as well as industrial gases production and sales.

SASPG boasts of excellent fabrication facilities, strong technological ability and perfect inspection measures. With a provincial level technical center, Sichuan cryogenic equipment research institute and welding institute, the company is endowed with very strong research & development and design and fabrication capability. The technology and performance of the products have already reached the international level. The company has acquired the pressure vessel design and fabrication certificates issued by the Chinese government for Class A1, A2 and C2 pressure equipment and B3 certificate for liquid cylinders, ASME certificate, U & U2 stamps, ISO9001-2008 quality system certification and Chinese military product quality certification.

In the years of development, the company has gradually formed its four main lines of business, i.e. air separation plants, LNG plants, cryogenic liquid storage and transportation equipment and industrial gases as well as their associated equipment fabrication business. In this way, SASPG has already established a production structures based on the pattern of "Four Main Lines of Business and Diversified Development".

SASPG has always paid great attention to research and development and consistently increased investment to upgrade the technology, such as improving the efficiency of the fabrication facilities and introducing first class international design and fabrication soft wares to improve the quality of the products, which have already resulted in remarkable progress. The company can produce more than 200 categories of products with over 1500 different specifications, which can not only be applied in cryogenic field but also in non-cryogenic industry.

The medium and large-sized air separation plants and various cryogenic liquid storage and transportation equipment designed and fabricated by SASPG have maintained the title "Sichuan Provincial Famous Brand" for consecutive 10 years.

SASPG has established excellent marketing and service network in China and has provided a large number of high-efficiency energy saving products for metallurgical industry, petrochemical industry, chemical industry, machinery building industry, national defense, space industry and health industry in China. More than 20 products have filled up the technological gap in China and more than ten different products have entered the international market. SASPG has consecutively maintained the leadership in the air separation field in China. SASPG has the import and export license and the products have already been exported to more than 30 countries and region. The company has already established a good reputation both home and abroad.
