The hard hat is an important accessory for gas cylinders. It is worn on the cylinder valve of each cylinder to ensure the safety of the cylinder valve from mechanical damage.

Why do gas cylinders have to wear hard hats?

Because the cylinder valve is mostly made of copper alloy, more fragile. Although some of them are made of steel, but because the structure of the bottle valve is smaller than the bottle body, the bottle neck and the bottle valve joint form a right Angle, it is not only the brittle defects of the bottle body, but also the highlight of the bottle body, the most vulnerable to mechanical damage or external impact. If, in the process of transfer, storage and use, the cylinder falls, falls, rolls or is hit by other hard objects due to careless damage, it is easy to present the situation that the bottle valve joint and the bottleneck joint crack at the root. Bottlenecks or the consequences of cylinder valves for cracking, the formation of high pressure gas bottle to lose control, high pressure gas jet, its reaction make cylinders dashed to the opposite direction and can make the machine equipment, buildings were damaged, and even form the casualties, high-speed jet of gas bottle will be decided by the nature of the gas inside the cylinder and bring more severe secondary accidents (such as fire, blasting, poisoning, etc.). If the bottle is filled with combustible gas, the static electricity caused by the fierce friction caused by the high speed injection or other ignition sources can cause combustion blasting.

Bottle valve exposed to the outside, in the process of transfer, storage, it is easy to invade dust or grease substances, and then bring risks.

In order to eliminate the risks mentioned above and avoid accidents, people wear hats on gas cylinders because they are an important safety accessory. Gas cylinder wear a hard hat, not only can protect the cylinder valve from impact, but also avoid oil, dust and other invasion. Therefore, it is required that the bottle-making units should be equipped with hard hats when the cylinders are manufactured. Put the helmet down to a fixed place when using gas. Put the cap on and tighten it after use. Do not throw it about.
