“I’m experiencing intermittent oxidation in my furnace. Could leaks in the nitrogen houseline be the problem?”
Yes, leaks in any pressurized high-purity gas line can cause intermittent oxidation. There are several possible causes. One is through retrodiffusion—the movement of impurities from the surrounding air to a high-pressure, low-impurity gas houseline. This is driven by concentration gradients, not pressure gradients, and is aggravated by changes in flow rate, pressure or piping temperature.
Air Products industry specialists can help you determine the cause of your problem. Since the oxidation is intermittent, you’ll need to continuously monitor your nitrogen houseline for leaks with a trace oxygen analyzer. For combustible gas lines, a combustible gas sniffer can also be used. Once impurities are found, the source of the leak can be identified using various techniques, including soap bubble testing, static pressure testing or helium mass spectrometry. Leaks often occur in weld cracks, mechanical joints, valve packing and loose fittings.
Industrial Gas Audits and Leak Detection Services
Audits and leak detection services can be comprehensive assessments of the entire gas supply system, or specific to gas or process equipment that use the gas.
Additional Services 
On-site Gas Generation
Supply options for nitrogen generators include cryogenic, adsorption, and membrane technologies. These offerings allow us to meet all typical flow, pressure, and purity requirements where on-site nitrogen gas generation is the best supply mode.
