FAQS on gas welding hose
Q: What safety standards apply to gas welding hose pipes?
A: Gas welding hose pipes must comply with ISO 3821 or BS EN 559 standards for flame resistance and pressure tolerance. These standards ensure compatibility with welding gases like oxygen and acetylene. Always verify certification marks and manufacturer specifications before use.
Q: How do I choose the right welding gas hose length?
A: Select a welding gas hose length based on workspace mobility needs while minimizing excess to reduce tripping hazards. Ensure the hose reaches equipment connections without stretching. Opt for pre-cut lengths or consult manufacturer sizing charts for precision.
Q: Can gas welding hoses handle mixed gases?
A: No, dedicated hoses are required for fuel gases (red) and oxygen (blue) to prevent chemical reactions. Mixing gases in a single hose risks combustion or degradation. Always use separately labeled hoses per gas type as specified in safety guidelines.
Q: What causes gas welding hoses to deteriorate prematurely?
A: Exposure to UV light, extreme temperatures, or oil contact accelerates hose degradation. Physical damage from kinks or abrasion also weakens structural integrity. Regular inspections help identify cracks, blistering, or stiffness indicating replacement needs.
Q: Are there temperature limits for gas welding hose operation?
A: Standard gas welding hoses typically operate between -25°C to 70°C (-13°F to 158°F). Extreme cold makes hoses brittle, while high heat softens materials. For specialized environments, use hoses with reinforced thermal resistance or consult manufacturer ratings.
