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.
