Cryogenic Vacuum Insulated Liquid Nitrogen Dewar Cylinder

Description

Welding thermal insulation cylinder, commonly known as dewar is liquefied natural gas (LNG), liquid oxygen, vehicle of natural gas, cryogenic liquid storage devices, widely used in the production of liquefied gas storage, transportation, use, and other fields, is particularly important for cylinder sealing, any leak can lead to the loss of the gas, if the bearing is gas or flammable gases, There is a risk of explosion, so leak detection for dewar (welded insulated gas cylinders) is very necessary.

Specification

Matters needing attention

1. During transmission, a special delivery hose is needed to connect the cylinder in and out of the liquid valve (DPW cylinder is the liquid inlet valve) with the supply source, and tighten to ensure no leakage of dewar bottle.

2. Open the discharge valve and inlet and outlet valve of the low-temperature dewar bottle, and then open the supply valve to start filling.

3. During the filling process, the pressure in the bottle is monitored by the pressure gauge and the discharge valve is adjusted to keep the pressure at 0.07~ 0.1mpa (10~15 psi).

4. Close the inlet and outlet valve, discharge valve and supply valve when the required filling quality is reached.

5. Remove the conveying hose and remove the low-temperature dewar bottle.
