Materials used in regulators, particularly elastomeric or rubber materials, will deteriorate over time. The composite bonnet and the outlet valve are incorporated into the regulator body to reduce weight.
To access your account please follow the below steps. If the gauge pointer starts to decrease, then the operator can open the source valve slowly and resume normal activities. If the gauge pointer does stop and level out at a pressure a few pounds above the starting pressure, this is called Lock Up and is common in the regulator.
You should never change gas service or CGA as there may be issues. inlet pressure: 3000psig(207bar),Outlet pressure range: 0
An overnight test will show smaller leaks and sometimes is better because it gives an early indication of issues with the seat. "When do I need to replace my regulator?"
Specialty gas regulators have metallic diaphragms, so not backing out the pressure adjustment knob before connecting a new regulator can cause diaphragm failure.
Once the detected leak area has been identified and addressed, the operator can repeat this test on other areas of the pressure-reducing device. Female NPT as InletA,Conn2:1/4in.

This short test will give an indication of gross failure of the seat.
After the visual inspection has been completed the regulator can be connected to the cylinder and pressurized. Another field test that an operator can perform on a pressure-reducing device is a Leak Check.
In this pamphlet, CGA states that Regulators do not have infinite service life, and they require periodic maintenance.
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. Certain parts of this website require Javascript to work. At this point, the pressure-reducing device needs to be removed from service and either replaced or repaired. This port must be open for the diaphragm to operate correctly.
This webiste use cookies. In cold climates, the water could freeze, causing the bourdon tube to rupture and gas to vent to the atmosphere. If the regulator is left in the open position, pressure will rapidly hit the metallic diaphragm and can cause crease and deformation.
Dont forget to reset the application pressure back when completed. 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. Your feedback is appreciated. If a leak is detected, shut down the gas source, reduce pressure to atmospheric and tighten the leaking connection (do not try to tighten any fitting while the pressure-reducing device has pressure inside it).

A specially designed, convoluted Hastelloy C-22 diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. Attorney Advertising. SNOOPTM is not an approved leak solution in high-purity applicationsAirgas recommends an ammonia-free solution instead. During this test the operator inspects the function of the outlet gauges by rotating the pressure reducing valve's knob. ;[8!}o3bxa'NP0Th]Ul8. The operator will need to visually watch the outlet gauge of the pressure-reducing device for two to five minutes. Learn more. Details can be found on a page Privacy policy.

The next test to verify that the pressure-reducing device is working correctly is Performance Pressure Test 2. Bonnet Vent Ports (with optional bonnet vent adapters) allow venting of hazardous gases in the event of diaphragm failure. The optional bonnet vent adapter enables venting hazardous gases in the event of diaphragm failure. We use cookies to improve your browsing experience and help us improve our websites.
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. A regulator (or changeover manifold) can last several decades if properly taken care of. Clean Peaks: Winter 2015 Regulator Maintenance. The regulator has a unique design to reduce weight and make the regulator more durabe. Threadless Seat Design provides longer regulator life. When a diaphragm fails, gas will vent through the bonnet vents if either the diaphragm seal is broken or the diaphragm breeches. 1 0 obj

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. 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. CGA indicates that after a period of time (e.g., five years), these regulators should have their elastomeric parts replaced.

A%qFjd+$Cnk3~kp3`=66lCzU/ `H\ 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. "What regular maintenance should I be doing?" 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. Agree
This should not be confused with Supply Inlet Effect, which you would see in single-stage regulators. In 2011 CGA updated pamphlet E-15 Periodic Service Program for Industrial Gas Regulators. This general-purpose, single-stage regulator is well suited for closely monitored, short run work. If you want to sign in with another account pleasesign out, Prostar
