Sichuan Air Separation Plant Factory was established as a specialized air separation unit manufacturer in Zigong, Sichuan, China.
The factory moved to Jianyang, Sichuan, China.
The factory made the first air separation plant with a capacity of 1000Nm3/h.
By forming its own sales team, the factory was no longer just a production-only factory, but a supplier with services.
The 400m3 cryogenic storage tank was successfully made.
The factory obtained pressure vessel design and manufacture certificate (A Class).
The factory got ASME certificate and U, U2 stamp issued by the National Board of Boiler and Pressure Vessel.
Hangzhou Chuankong General Equipment Co., Ltd was established.
Sichuan Air Separation Plant (Group) Co., Ltd (SASPG) was named, including Sichuan Air Separation Plant Factory, Jianyang Heat Exchange Factory, Sichuan Hemispherical Vessel Head Manufacturing Co., Ltd., and Sichuan Jianyang Chahu Air Separation Technology Development Center.
SASPG cooperated with Air Liquide for the development of 6000Nm3/h air separation plant.
SASPG cooperated with Praxair, and this period witnessed the quick technical development of SASPG.
SASPG transformed from a state-owned company to a joint stock company.
The 28000Nm3/h air separation unit was developed with out patent technology.
Zhejiang Dachuan Air Separation Plant Co.,Ltd. was established in Huzhou, Zhejiang, fully held by SASPG.
- Till 2013
Now SASPG has 40 subsidiary companies and holding companies. We have produced more than 2000 sets of air separation plants, more than 8000 pieces of cryogenic storage tanks, more than 100 sets of CO2 generators, etc. They were delivered to customers in more than 50 countries.
We implement a testing standard that is higher than the national one, to ensure that every product has a long service life. We have hydrogen mass spectrometer leak detector, impact testing machine, tensile testing machine, metallographic analyzer, nondestructive testing equipment, etc. We also have a complete inspection and testing plan, and all the inspection records and test reports are complete and traceable.
Our new factory is located at the band of the Beijing-Hangzhou Grand Canal. We have our own private basin wharf in a size of 46m×16m×8m (l×w×h). When the production is completed, the finished equipment can be lifted aboard directly from the workshop and transported by river to Shanghai or other ports (150km from Shanghai port). The river transport can go beyond restrictions on large pressure vessels of land transport. Even the 600m3 tank can be easily and quickly delivered to the port.
