Please make sure you refer to your condensing unit specifications when setting pressure on Nitrogen regulator!!! Nitrogen Gas has the following qualities: (a) inert gas , very dry and non-flammable; (b) does not go into solution with refrigeration oil to create non condensable pressure problems (i.e., after leak testing an HFC (R-134a) system using R-22 and nitrogen, there is typically zero percent non condensables (nitrogen or air), if evacuated afterwards). Favourite answer. The total lack of knowledge and understanding on your part makes one hesitant to arm you with any pressurized gas, nor the knowledge of how it is used. Systems are pressure tested to ensure they are: • Safe – for this test a pressure above the system’s maximum allowable pressure (PS) is used; • Leak tight – this test is at PS. SS4. Carrier-gas leak testing can instead be used with smaller parts. Inert nitrogen gas (used an the pressurizing medium) also safely purges the process system of oxygen and flammable gases, while helium in trace amounts provides a means of detecting leaks as low an 0.03 m3/yr. A hydraulic test using water is much better, safer, and will show leaks much sooner than a gas. Nitrogen gas applications are seemingly endless.

Answer Save. If leak testing by means of pressure measurement reveals leakage in excess of permissible levels, the next step is to locate the leak. The patented clam shell device (image, below) uses low pressure nitrogen to create a helium-free environment, allowing the mass spectrometer gas analyzer to sample and detect micro-leaks. Methods of detection include hydrostatic testing, infrared, and laser technology after pipeline erection and leak detection during service.. These are available from your nearest BOC retail store or by calling 0800 111 333.. all equipment in a gas system must be checked for leaks after assembly and corrective action taken before use Some nitrogen leak detectors are designed to be set to test for a variety of different gases, allowing the devices to be more versatile. Nitrogen is non flammable gas, more stable than air is although not completely inert. Nitrogen gas is injected under pressure to assure good connections in welding and threaded pipefittings. Some companies that use nitrogen gas in large volumes opt to invest in an on-site nitrogen generation system. 1 decade ago. This allows them to be moved to the site of any suspected leaks. 0 0. Let us help you spec the perfect solution: on-time and on-demand. Rather, it uses a stream of trace-gas … Nitrogen Generator Membrane Trailer Systems On Site Gas is one of the top manufacturers of mobile nitrogen generator systems worldwide – available in flows up to 90,000 SCFH and purity as high as 99.9%. Hi All, This is a new install, i'm running a leak test after running line set. On Site Gas Systems is a pioneer in oxygen and nitrogen generator technology. Helium molecules are far smaller than nitrogen molecules and so are better able to pick up small leaks in a refrigeration system. Our precision-engineered oxygen and nitrogen generation systems are used throughout the world in mission-critical applications, across dozens of industries. Repeat- MUCH SAFER! What happens to the nitrogen used for leak detection in a system? Often times, a HVAC manufacturer will pressurize the coils in before being shipped to confirm that there are no leaks. No matter what you’re looking for, we can design and build a nitrogen or oxygen generator to meet your needs. Découvrez comment nous utilisons vos informations dans notre Politique relative à la vie privée et notre Politique relative aux cookies. In any event even if leak tight any flange/connections will be considered as a zone 2 potentially explosive atmosphere and if hydrocarbon only, then the main risk would be associated with explosion/jet fire. Many of our original generator systems are still going strong after 30 plus years. We offer the following gases for pressure testing and to aid leak detection: Nitrogen. Learn more about how an onsite nitrogen generator can help support your leak detection & testing efforts. Budney Industrial Park Newington, CT 06111, Telephone: 1-860-667-8888 USA Toll Free: 1-888-748-3429 Outside US: 1-860-667-8888 Fax: 1-860-667-2222, Portable Oxygen Generation Systems (POGS). test using nitrogen. The leaks, which cause the test pressure to decrease more than one graduations on test gauge during the holding time, shall not be acceptable. If the leak rate is specified for air, but helium is being used, proper conversion data must be used to provide a more precise leak rate. With nitrogen and a few common hydraulic hoses and fittings I can set up for a strength test and get it under way in a few minutes working alone. Regards This method does not accumulate the trace gas in the test volume. A nitrogen/helium mix provides the following benefits: improved detection. This should result in a longer product life. It is a very poor procedure to test with a gas such as Nitrogen. With pressurized Nitrogen. Total time required for the test is about 12 hours. The values did change since the test was started but i'm getting a PSI increase, this can be due to temp change but not 100% sure.. Typically, nitrogen gas leak detectors are portable, handheld devices. 1. In many high pressure testing applications for leak testing, gaseous nitrogen is utilized as a medium due to its low investment cost. The R-22-nitrogen leak test gas is not subject to the prohibition on venting because in these cases, the ozone-depleting compound is not used as a … Never use air or pure oxygen. I use nitrogen with 22 as a tracer gas, which is EPA Ok, and one of my leak detectors usually my Inficon D-tek or my H-10. The atmosphere we live in, the air we breathe every day consists of 78% Nitrogen, 21% Oxygen and 1% traces of other gases. PSA Nitrogen Generator On Site’s PSA nitrogen generator technology assures quick returns on your investment and stable year-to-year gas costs. It also shows how to calculate the test pressures in accordance with EN378. 1. Nitrogen Membrane Generator The nitrogen membrane generator is a complete turnkey system. A mass spectrometer is used to detect extremely low levels of the helium detector gas. I can also get a tanker truck of nitrogen with an extra trailer load for big jobs. This is extremely important! Using this technique you can leak test to find smaller leaks than with other test processes, using a largely temperature independant, dry technique. The trace gas enables electronic leak detectors to be used to detect the vicinity of the leak. if oxygen level falls below 16%, we will die of asphyxiation.Nitrogen gas behaves somewhat like a diluent or buffer gas in the atmosphere. Many of our customers in the oil & gas industry use nitrogen to perform tests on BOPs, SCSSVs, Christmas trees and drilling equipment. First pulled a vacuum then i did the leak test with soap and didn't find any noticeable leaks.. Then I left it pressurized over night and now its at the 20hr mark.. previously installed pressure and piping equipment that has undergone an alteration or repair to its boundary nitrogen is easy to compress into liquid and when released expands rapidly to gase form so easy to transport and nitrogen is made at various industries. A mixture of Nitrogen & 15% by volume of Ammonia is used to pressurize the shell side.
