Cryogenic API600 Gate Valve
Cryogenic Definition:
Low-temperature parts into liquid nitrogen tank insulation a certain length of time, to reduce its due to temperature differences andmetallographic changes resulting from the deformation,which increases when the low-temperature valve sealing performance of a processing method.
Cryogenic method: soak the parts to be processed into liquid nitrogen tank for cooling, when parts of 196 degrees centigrade temperature reaches-, start insulation 1 ~ 2 hours, then remove the carton natural treatment to room temperature, repeat cycle twice.
As a general rule, use of the valve below 101C, before finishing the main part for cryogenic. But if the user requires, above-101.C working temperature valve parts for cryogenic.
