Gas Regulators

Operating Instructions

Pressure regulators are precision manufactured instruments which, with correct use will provide reliable and trouble free service.

Before the regulator is fitted to the cylinder

Check that the cylinder socket and the regulator connections are free from oil, grease and damage. Open the cylinder valve momentarily to eject any water or foreign matter form the seating (Except in the case of hydrogen). Ensure that the blast is not directed at persons or naked flames.

Connecting to the Cylinder

Connect the regulator to the cylinder valve (left hand for acetylene and other combustible gases). Right hand for oxygen and others non-combustible gases, using the correct spanner and ensure a gas tight seal. check that the pressure adjusting screw of the regulator is fully released.

Connecting Operation

Connect downstream equipment and open the cylinder valve slowly.

Check all joints for leaks using a 0.5% Teepol in Water Solunon. The contacts of the cylinder will register on the cylinder contact gauge and will decrease to zero as the cylinder empues. The contents are shown in baslbf/m2 (1 bar x 14.5 ibf/m2), To set pressure, screw the pressure. adjusting knob clockwise until the required outlet pressure registers on the outlet gauge, when gas is flowing, there may be a reduction in pressure and adjustments be made purge the gas line before lighting the equipment.

Finish of Operation

When work has stopped, close the cylinder valve, venl gas form gas the hoses and unscrew the pressure adjusting knob.

Safety points to Observe

• Avoid knocks or bangs.
• Do not use regulator for Pressures greater than its design pressure.
• Regulators are less likely to be damage when working under design pressure.
• Regulators are less likely to be damaged when the Cylinder are secured in a trolly.
• inspect the regulator periodically for damage or signs of misuse and the gauges for accuracy.
• Test for leaks using a 0.5% Teepol in Water solution.
• Regulation exist governing the use of acetylene and users should comply with Order in Council No. 30 and self guidance if in doubt form H.M. inspectorate of explosives.
