Seeking help with the Kaifeng expander! ! !

How are the expansion joints in Kaifeng performing? Who uses it? Please let me know. Thank you! ! ! !
Kaifeng, a recognized industry supermarket. The expansion machine industry is widely recognized to be based in Jianyang, Sichuan; as for expansion machines produced in Kaifeng, it depends on which company manufactures them. If the poster wants to seek advice, it’s best to consult a supplier in Kaifeng; they will arrange for you to make an on-site visit. (For reference)
For low-pressure, small-sized machines, there are many options available in China; however, for those with high capacity, medium pressure, a large expansion ratio, a significant drop in enthalpy, and extremely low flow rates, it is recommended to choose domestic machines from Chuan Kong if such options are available
Upstairs is Chuan Kong, I’m also from Chuan Kong
Ours is an empty expansion machine that hasn’t been started yet; I’m not sure what’s going on
I trust the expanders from Xianyang, Sichuan, but the expanders from Kaifeng that are used in our small oxygen production units, which produce 3,800 cubic meters of oxygen per hour, have been in use for 6 years without any major problems. In my opinion, quality is certainly an important factor – it should be satisfactory in all cases – but what’s more crucial is careful handling during startup and proper maintenance during operation.
