What is the bursting pressure of new oxyfuel hoses?

• A. 400 psi
• B. 600 psi
• C. 1000 psi
• D. 200 psi

Answer: (A)

Bursting pressure is the pressure at which a hose would fail or burst, not the pressure you normally run the system at. New oxyfuel hoses are built with a safety margin so they can withstand more than the usual operating pressures. A bursting pressure around 400 psi is a common spec for fresh hoses, giving a comfortable buffer above typical oxygen and acetylene operating pressures. This helps prevent rupture from pressure spikes or accidental over-pressurization. Higher values like 600 psi or 1000 psi would be more than necessary for this purpose, and 200 psi is typically closer to operating pressure, not the burst strength.
