Why we have to clean the inside of the gas cylinder?
- There are cases at official gas cylinder inspection when gas cylinders cannot pass on the tests without proper inner cleaning The inner part of the gas cylinder cannot check. The inspector cannot see the wall of the cylinder bacuse it is dirty. The inspector cannot judge if the gas cylinder is safe or not. If there is no proper cleaning, then the gas cylinder is a scrap!
- At scuba diving, at firemen breathing protection the gas will contact our body directly. We breath the gas from the gas cylinder. The inner contamination could damage our health. It could also cause direct emergency cases. Nobady should be in a situation when underwater the used scuba gas cylinder’s valve blocked because of an inner contamination! I have a personal friend from gas cylinder refurbishment, who says that she will just make a dive with the gas cylinder what was cleaned by her!
- The biggest gas factories like Linde, Messer, SOL will make it obligatory to clean the inner part of the gas cylinders on certain fields. This kind fields are food industry (food grade CO2, food grade Nitrogen) medical (medical oxygen, medical dinox). The Luxfer Gas Cylinders made a succesful beverage campaign in the UK, when they advertise the inner cleaniness of the aluminium gas cylinder. You won’t feel the tase of rust in your beer!
- The inner cleaniness of the gas cylinders is very important on the high purity gas and gas mixture filling! It is doesn’t matter if a high priced gas – sometimes more expensive than the gas cylinders itself – could be used for 6 month or could be used for 2 month. If the gas will lost its stability because of the dirty gas cylinders then you have to trash it before you could consume the complete contains of the gas cylinder.
The above mentioned examples show you some cases when you could save your money only with gas cylinder inner cleaning. The gas cylinder will reaim in service. The usage of the gas cylinder is healthy and safe. The laboratories and calibration stations could be sure they could use the gas for longer period.
