Discussion on regulations for gas welding (gas cutting) management
Thread Content
During the process of oxygen and acetylene cutting, managers require that oxygen cylinders be placed upright. There is no issue with using acetylene cylinders upright, but is it necessary to use oxygen cylinders upright as well? Installation sites are generally located in outdoor environments where the sunlight is intense and abundant in summer; therefore, safety regulations require that gas cylinders be protected from exposure to direct sunlight. Scorching sun heat is at most in the high tens of degrees – what kind of danger can that pose? Who can provide a quantitative explanation? Thank you!
1. It is necessary to keep it in an upright position; many construction sites are quite chaotic. If the pressure regulator is knocked over, the consequences can be catastrophic. It’s somewhat better if only the oxygen hose gets damaged as a result； 2. Safety risks are at most semi-quantitative; if it is calculated that there is a risk of explosion or overpressure, then oxygen cylinders cannot be used in that way, and many more safety measures must be implemented ； Our requirement for safety is that measures must be in place to avoid potential risks.
I agree with your view. However, if the design margin is too large, doesn’t that lead to a waste of resources?
The design pressure of pressure vessels should be no lower than the operating pressure; this is a design issue, not an operational one； For use, it is essential to avoid overpressure, as there is still the threaded connection part even if the bottle itself is in good condition.
Yes. Avoiding overpressure during use is something that must be taken into consideration. By how much does the pressure of gas cylinders increase at different temperatures? Does anyone have experimental data that can be used as a reference?
