Acuren Inspection Ammonia Services group now offers mobile access to the vital inspection report information your team needs. The vast majority of industrial refrigeration systems in operation today use anhydrous ammonia as the refrigerant. Start your mechanical integrity program off the right way. Periodic inspection must be performed to determine if hydrostats are free of evidence of tampering, damage, corrosion, leakage, or foreign matter that might prevent proper operation. (i.e. The following table provides guidance, presents unique challenges since the insulation itself can conceal active corrosion. Peterson, J., "Piping System Preparation", IRC Research and Technology Forum, Moist ammonia will not corrode iron or steel, but will react rapidly with copper, brass, zinc and many alloys, especially those containing copper. Insulation will be needed. AMMONIA-RATED SYSTEM PIPING Minnesota Rules, Part 1513.0160 requires that system piping (piping, fittings, flanges, other components) must be made of steel or other material suitable for anhydrous ammonia service, and must be designed for a pressure not less than the maximum pressure to which they may be subjected in service. The information provided is useful for various industries where corrosion inhibitors are needed to protect mild steel structures which are being exposed to hydrochloric or sulphuric acid solutions. Acid solutions have been commonly used in these industries as pickling agents to remove rust or any scale from the mild steel surface. Refrigerant Piping and Heat Transfer Components. 2. effective at locating areas of active external corrosion on uninsulated piping and vessels and such inspections, prevent reoccurrence of corrosion.
