I will summarize them today.: 1. What is the filling pressure of acetylene and oxygen bottles? What should be the normal pressure range of an instant bottle? What should the weight of these media be after filling? That is, what is the weight of acetylene and oxygen in the bottle? 2. The medium in the bottle cannot be used up during use. What is the minimum remaining pressure? 3. What is the operating pressure range of acetylene and oxygen bottles? That is, within what range should the pressure after the pressure reducing valve be? 4. When an empty bottle is taken to a gas station for refilling, is the gas station obliged to replace it with nitrogen to avoid the formation of explosive gas? Replies are scored, so please write down the corresponding criteria when answering. Thank you!
Acetylene cylinders generally have a reloading capacity of 3kg and a pressure of 2.5mpa, which is equivalent to a standard volume of 6 cubic meters. Oxygen has a reloading capacity of 6kg and a pressure of 15mpa, which is equivalent to a standard volume of 6 cubic meters. In fact, generally reloaded gas cylinders have a standard volume of 6 cubic meters and a pressure of about 15mpa. Acetylene is dissolved in acetylene, so there is some difference. For example, nitrogen has only 0.8kg per bottle, and argon has 1.4kg per bottle, but the pressure and standard volume are the same as oxygen. The volume of carbon dioxide is slightly different, because the liquefaction of carbon dioxide is not stable. As the climate and temperature change, the filling company will make some adjustments to its filling volume.
Of course, you cannot use up all the gas bottles. It is not allowed to use up all the gas bottles. This is very dangerous. For example, using up acetylene gas and chlorine gas bottles is almost equal to causing an accident. However, please check the relevant filling safety regulations yourself for the specific amount. * * There are relevant standards
It is necessary to replace empty bottles, not only new bottles, but also recycled bottles need to be replaced before filling.
Thank you, Brother Hou, but my question has not been fully answered yet. Please help experts, it will not be in vain.
Please download the following two specifications and study them carefully* , the regulations are very detailed, there are them in this forum, search and take a look. "GB 14193-2009 Liquefied Gas Cylinder Filling Regulations" "GB 13591-2009 Dissolved Acetylene Cylinder Filling Regulations" "Gas Cylinder Safety Supervision Regulations" * * Order No. 46 of the General Administration of Quality Supervision, Inspection and Quarantine "Gas Cylinder Safety Supervision Regulations" (2001)
