introduction to vacuum storage tank (part i) - doer equipment
1、equipment inner tank
as the main container containing low-temperature medium, the inner tank is the core component of the equipment. the utility model is mainly composed of a cylinder body and heads at both ends, and is connected with corresponding pipelines to realize various functional operations. ensure the product quality from the aspects of material re inspection, nondestructive testing, air pressure test, helium mass spectrometry leak detection, air tightness test and so on.
2、equipment outer tank low alloy steel q245r or q345r with good weldability conforming to gb713 is used as the protective shell of the thermal insulation system. its compactness will directly affect the interlayer vacuum and play a decisive role in the thermal insulation effect of the equipment.
