Significance of special gas cylinders such as hydrogen chloride wearing shockproof rings
Shockproof ring seems to be a very small equipment, but because it is easy to damage, loss and other circumstances caused by the increase of loss, not all enterprises are willing to increase the investment; In particular, the "Regulation on filling compressed Gas Cylinders" implemented in 2018 also removed the requirement on wearing shockproof rings. So is it meaningless to use shockproof rings for gas cylinders?
In fact, the shock ring in transportation and loading and unloading, and even in the process of use also played a certain safety role.
According to the provisions of gas cylinder safety supervision, the transport unit of gas cylinders must strictly abide by the relevant provisions of the state for the transport of dangerous goods. When transporting and loading and unloading cylinders, it is necessary to wear cylinders caps (except for cylinders with protective covers) and shockproof rings (except for containerized cylinders). How to understand the requirements of this regulation on shockproof ring? In other words, the process of cylinder transportation and loading and unloading is required to be equipped with shock rings.
Friction and collision between cylinders during transportation, as well as the inevitable turbulence caused by road conditions, may increase the risk of cylinder damage. Even in the process of using gas cylinders in some units, improper operation of staff also exists the occurrence of dumping, collision and other situations. Shockproof ring can absorb shock well and reduce the safety risk caused by vibration. In particular, because of the particularity of special gases, some have the risk of ignition and explosion, some have high corrosion, such as hydrogen chloride #hcl#, and some have toxicity, such as high purity chlorine gas. A little safety hidden danger is a risk.
In the current regulations do not require the use of shockproof rings, there are still enterprises willing to increase their own costs to ensure safety, with precious life safety consciousness in the first place.
