Notes

Bottled gas products for high pressure filled gas, use should be reduced pressure before use. All the packaged gas cylinders have the service life, and the expired gas cylinders must be sent to the department for safety inspection before they can continue to use. When each bottle of gas is used to the exhaust gas, the residual pressure in the bottle should be kept at 0.5MPa, and the minimum residual pressure should not be less than 0.25MPa. The bottle valve should be closed to ensure the quality and safety of gas. Bottled gas products should be stacked up in classification during transportation, storage and use.
