Precautions 

(1) High-pressure gas cylinders must be classified into sub-offices for storage and storage, and should be kept upright when placed upright. The cylinders should be far away from the heat source to avoid exposure and strong vibration. The general laboratory gas cylinders should not exceed two bottles.

a. On the shoulder of the cylinder, mark the following markings with steel seals. Manufacturing Date Cylinder Model Working Pressure Pressure Test Pressure Air Pressure Test Date and Next Date, Gas Volume, Cylinder Weight.

b. In order to avoid any confusion when using various cylinders, the cylinders are often painted in different colors, and the gas names in the bottles are indicated.

(2) The pressure reducer used on the high-pressure gas cylinder should be classified according to the specific requirements. When installing, the screw should be screwed tightly to prevent leakage; when the pressure reducer and the on-off valve are opened and closed, the action must be slow; , After opening the pressure reducer; run out, turn off the switch valve, put more than gas, and then off the regulator. Must not stress reducer, not the switch valve.

(3) When using high-pressure gas cylinder, the operator should stand in the vertical position with the cylinder interface. Operation is prohibited beat hit, and often check for leaks, pay attention to the pressure gauge readings.

(4) oxygen bottles or hydrogen bottles, etc., should be equipped with special tools, and is strictly prohibited oil contact. Operators should not wear clothing gloves that are stained with various greases or that may cause static electricity to avoid burning or exploding.

(5) Flammable gas and gas cylinder supporting combustion gas, and the distance from the open flame should be greater than 10 meters (indeed hard to reach, you can take measures such as isolation).

(6) cylinders after use, should be required to stay more than 0.05MPa residual pressure. Flammable gas should be left 0.2MPa ~ 0.3MPa (about 2kg / cm2 ~ 3kg / cm2 gauge) H2 should be kept 2MPa, to prevent the danger of re-inflated, not exhausted.

(7) Various cylinders must be technically checked regularly. Gas cylinders filled with general gas shall be inspected once every three years; if serious corrosion or serious damage is found during use, they shall be inspected in advance.

FAQ

1. What's your product price?

Because each gas price depends on your quantity and purity requirements, it is difficult to give a fixed price. If you are interested in some gases, please provide your details. I can offer you an offer.

2. What's the min order?

Different products with different MOQ, please do not hesitate to tell us your needs

3. Is there any cautions to use gas cylinders?

1) The use and testing of gas cylinder shall be subject to “Safety inspection regulations for gas cylinders” issued by State Bureau of Quality and Technical Supervision. 

2) The gas cylinder shall away from heat and sunlight exposure. The distance from fire should be no less than 10 meter. And it is prohibited to hit the cylinders.

3) It is prohibited to use fire to heat the valve if it was frozen.

4) The nozzle of the gas cylinder was strictly prohibited from oil contamination 

5) The gas in the cylinder cannot be entirely exhausted, it would be better to remain not less than 0.040 MPa residual pressure

6) The filling pressure of gas cylinder cannot exceed the prescribed pressure.
