What is ISO 2503 - Gas welding equipment about?
ISO 2503 discusses gas welding equipment. Gas welding equipment is among the most essential tools for a welding professional. Welding machines generate heat that melts metal parts so that these parts can be joined. ISO 2503 specifies requirements for single or two-stage pressure regulators without flow-metering devices for connection to gas cylinders used for:
- Compressed gases up to 300 bar1) (30 mpa)
- Dissolved acetylene
- Liquefied petroleum gases (LPG)
- Methylacetylene-propadiene mixtures (MPS)
- And carbon dioxide (CO2)
ISO 2503 also specifies requirements for single or two-stage pressure regulators with flow-metering devices for connection to gas cylinders used for:
- Compressed gases or mixtures up to 300bar (30 mpa)
- Carbon dioxide (CO2)
Note 1: ISO 2503 does not cover pressure regulators having a nominal outlet pressure p2>20bar.
Note 2: ISO 2503 does not cover pressure regulators intended for direct use on cylinder bundles. Such regulators comply with the safety requirements of ISO7291, in particular with the adiabatic compression test for oxygen regulators.
Who is ISO 2503 - Gas welding equipment for?
ISO 2503 on gas welding equipment is useful for:
- Gas cylinder manufacturers
- Cylinder welding industry
- Design engineers
- Quality control personnel
- Research and development facilities
Why should you use ISO 2503 - Gas welding equipment?
All pressure regulators, except that for acetylene or LPG, shall be supplied with a pressure-relief device (for example, pressure-relief valve or burst disc) designed to vent excess outlet pressure in the case of partial regulator-seat malfunction. It is demonstrated that a sufficient level of safety is ensured in accordance with ISO 2503. A safety-risk analysis or special safety precautions is considered.
Pressure regulators and pressure regulators with flow-metering devices are designed and constructed in such a way that the application of pressures given in ISO 2503 in the high-pressure and low-pressure-regulator chambers does not lead to permanent deformation. Using ISO 2503 you can specify requirements for single or two-stage pressure regulators with flow-metering devices for connection to gas cylinders.
