Ammonia Piping Abbreviations: The 2014 revision contains 28 abbreviations versus 17 contained in the 1991 Guidelines. Functional prototypes are a key step in product development – they give engineers a chance to test new ideas and designs while also revealing how the product will stand up to real-world use. IIAR also states that facilities may select an alternative color scheme as long as that color scheme is consistent throughout a facility. 114 Identification of Ammonia Refrigeration Piping and System Components, and perhaps the biggest change is that labels must now be orange, not yellow.

HTRL, HTRS, MRTL, MTRS, HTS, DR, MTS, BS, ES, HSS, For Services within -1 Degrees F to -20 Degrees F (Saturated pressure  3 PSIG – 15 PSIG): And when it comes to functional prototypes, 3D printing is rewriting the rules of what’s possible. R-717 Tip of the Day. Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. Pipe insulation is also considered part of the piping system. By joining you are opting in to receive e-mail.

IIAR Ammonia Refrigeration Piping Handbook. and practitioners in the ammonia refrigeration industry have used varying color schemes, or no color schemes, to identify ammonia refrigeration piping systems. Less Expensive - Ammonia refrigerators require narrower piping, which is less expensive to make. GCAP’s state of art training lab, which has doubled in size this year, has specialized training equipment for testing and learning that is found at no other training site. Our bright and durable ammonia pipe labels resist fading and deterioration. The basic ANSI approach wouldn’t clarify which pipe is which. Dia. Installation Details. Why color coding of piping material?During construction and fabrication, various grades of carbon steel, alloy steel, and stainless steel are used. The IIAR (International Institute of Ammonia Refrigeration), in conjunction with ANSI, issues guidelines for identification of ammonia lines. Your facility can/should adopt your own program. Recently IIAR published the November 2013 edition of the Condenser. both printed in colors above Marker Body “Ammonia” - black letters on yellow background The International Institute of Ammonia Refrigeration (IIAR) standardized ammonia pipe labeling when it published its bulletin #114, “Guidelines for Identification of Ammonia Refrigeration … We will mail out GCAP’s Videos free of charge.
