The pressure range of welding pressure reducers used in Kazakhstan follows international standards, with an input pressure typically of 15MPa (about 150bar) and an output pressure adjustment range of 0.02-4MPa (0.2-40bar) depending on the type and purpose of the gas.
The adjustment range of oxygen pressure reducers is usually 0.02-2MPa, acetylene pressure reducers are 0.01-0.15MPa, hydrogen pressure reducers are 0-0.2MPa, and nitrogen pressure reducers are 0.4-4MPa. These pressure reducers are mainly used for welding, cutting, and related processes, and can regulate the high-pressure gas (up to 30MPa) inside the gas cylinder to a stable output pressure required for operation.
The Kazakhstan market requires that welding pressure reducers must pass GOST-K certification to ensure that the products comply with local safety standards and technical requirements.
