The next test to verify that the pressure-reducing device is working correctly is Performance Pressure Test 2. !! The operator will need to visually watch the outlet gauge of the pressure-reducing device for two to five minutes.

During this test the operator inspects the function of the outlet gauges by rotating the pressure reducing valve's knob. The specialty gas industry follows the guidelines posted by the Compressed Gas Association (CGA). This means keeping many things in mind on a regular basis, including: changing the cylinder to prevent pressure slam of the diaphragm; never dropping the regulator; keeping impurities or foreign particles from getting into the gas service; and protecting the pressure-reducing devices from the elements. If the gauge pointer starts to decrease, then the operator can open the source valve slowly and resume normal activities. Aged elastomeric materials may exhibit hardening, stress cracking and other physical property degradation. The pressure-reducing devices used in the specialty gas industry have elastomeric seats, such as materials like PCFTE and PTFE. After the visual inspection has been completed the regulator can be connected to the cylinder and pressurized.

"When do I need to replace my regulator?" A regulator (or changeover manifold) can last several decades if properly taken care of. The operator will need to verify that the gauge is responding to the change in the pressure setting by seeing that the gauge pointer drops.

If there are any defects the product should be taken out of service and repaired or replaced. And happily, from the maintenance to testing, we've got the answers that should help clear things up. This test will require the operator to close the source pressure valve (cylinder valve) or inlet valve to the pressure-reducing device. When the gauge pointer levels out, the operator can reopen the source valve and the downstream valve to resume operations. hbbd``b`f@>[SI l D\0.[k2y:bA@r#3~` D

If the gauge pointer starts to rise and does not stop after two to five minutes, then creep is occurringwhich means the inlet pressure is leaking across the seat of the pressure-reducing device, trying to equalize the pressure coming into the device to the pressure going out of the device. These 316 stainless steel single-stage high-purity regulators are recommended for non-corrosive analytical, mildly corrosive and process applications where precise flow control is not critical. f]%[ Bonnet Vent Ports (with optional bonnet vent adapters) allow venting of hazardous gases in the event of diaphragm failure. hb`````Ja`a`Ab@A@PAV~\DWX"${dRhhrnn X}>n

Inlet Pressure:3000 psi,Outlet Pressure Range:0~100psi,Cv=0.05,Conn1:1/4in. For this test the operator will need to close the outlet valve or a downstream valve from the pressure-reducing device and the inlet source valve. This will cause the downstream pressure to equalize with the inlet pressure and the outlet gauge to fail. The operator of the device needs to inspect the regulator, the gauges (pressure indicators), valves, inlet connections and outlet connections for any obvious defects, or dirt or grease on the CGA. 2022 Airgas, Inc.

The operator will observe to see if the inlet gauge pointer decreases in pressure when the pressure-reducing device is delivering gas to the process or when the gas is being vented off. Once the detected leak area has been identified and addressed, the operator can repeat this test on other areas of the pressure-reducing device.

Seat failure happens as a result of particles getting into the regulator. It's easy to tell: the gauge will be pegged and may also contain water. When the pressure-reducing device is under pressure (both the high side and delivery side), the operator can use an approved leak test solution. 53 0 obj
