Requirements for use of steel seamless gas cylinders:

1. The safety condition of gas cylinders should be checked before use, and the gas contained in them should be confirmed. It is forbidden to use gas cylinders that do not meet the safety technical requirements; Operation should be carried out in strict accordance with the operating instructions.

2. The steel seal and color mark of the cylinder shall not be changed without permission.

3. Measures should be taken to prevent the dumping of gas cylinders when they are used vertically.

4. The gas cylinder can be moved by tilting and rolling with bare hands in short distance, and it can be transported by portable car in long distance. Should not throw roll, slip, turn over. When gas cylinders are used on site, they should be placed on special vehicles or fixed for use.

5, the use of oxygen or other strong oxidizing gas cylinder, the cylinder body, valve should not be contaminated with grease or other combustible. The working clothes, gloves, loading and unloading tools and tools of the user should not be stained with grease.

6, in the installation of pressure reducing valve or busbar, should check the clamp or connecting nut thread intact. Depressors, connectors, conduits and pressure gauges used to connect cylinders shall be marked and used on a particular type of cylinder.

7. When opening or closing the bottle valve, hand or special wrench should be used instead of hammer, pipe wrench or long-handle screw wrench.

8.open or close the cylinder valve rotation speed should be slow.

9. When the cylinder valve is found to leak, or open without gas, or have other defects, the cylinder valve should be closed, marked and returned to the cylinder filling unit for processing.

10. the bottle of gas should not be used up, should leave excess pressure.

11. in the use of possible backflow, the use of equipment should be equipped with a device to prevent backflow.

12. The gas in the cylinder should not be inverted to other cylinders; Do not dispose of residual gas in the bottle.

13. The use area of gas cylinders shall be equipped with empty bottle area and solid bottle area, which shall be clearly marked.

14. Do not knock or collide gas cylinders.

15. Arc welding should not be carried out on gas cylinders.

16. Do not use gas cylinders as supports or other unsuitable uses.

17. acetylene, liquefied petroleum and other gas cylinders are strictly prohibited to use lying down.

18. Gas cylinders shall not be stored and used in a closed and narrow space; The safe distance between flammable and combustion-supporting gas cylinders and fire sources should meet the requirements, and the place should be safe and reasonable.

19. The gas cylinder decompression instruments, valves, gas cutting tools and rubber hoses used in the field meet the standards and are connected reliably without leakage;

20. It is strictly forbidden to reverse the gas in the liquefied petroleum cylinder, and it is strictly forbidden to deal with the residual liquid in the cylinder by itself;

21. It is not allowed to excavate or repair the bottle body by welding;
