What is medical oxygen gas? What are the precautions for storage and use

2024-05-28

Medical oxygen gas is a gas used for medical emergency and auxiliary treatment of some diseases, with a purity of ≥ 99.5% and meeting certain standards for acidity, carbon monoxide, carbon dioxide, and other gaseous oxides. Medical oxygen gas is mainly separated from the atmosphere through cryogenic separation, and undergoes multiple compression, cooling, and distillation processes to remove dust, impurities, carbon monoxide, carbon dioxide, and water vapor.

What safety precautions should be taken when using welding gas bottle

2024-05-28

Small welding gas bottle are reusable mobile pressure vessels commonly used for storing and transporting permanent gases, liquefied gases, dissolved gases, or adsorbed gases. The nominal volume of gas bottle is generally between 0.4 and 3000 liters, and the working pressure is between 1.0 and 30 MPa. The construction of small welding gas bottle may include two or three structural types, and their bottle and head are usually formed by welding steel plates cold rolled. To ensure safe use, small welding gas bottle are usually welding with bases and covers on the lower and upper heads respectively, to protect the bottle valve and keep the bottle upright. The cover is usually fixed to the bottle ear with bolts.
