They're available in a variety of sizes and materials to meet your pipe marking needs. and practitioners in the ammonia refrigeration industry have used varying color schemes, or no color schemes, to identify ammonia refrigeration piping systems. I have been through ANSI to determine the piping color codes standard. Below one might find some that are commonly used today. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. When the term “ammonia refrigeration system” or “ammonia refrigeration plant” is used it means an ammonia vapor compression system. Excessive pipe corrosion can even lead to pipe failure and release of the contents into the environment - a critical concern, given the hazards and regulations associated with an ammonia leak. TABLE OF CONTENTS. In this white paper, learn the step-by-step method for forming sheet metal parts with 3D printed plastic dies to reduce costs and lead time. This manual summarizes the requirements of environmental and safety laws for anhydrous ammonia refrigeration system operators. Please contact us for these videos. To avoid mixing of this material and easy storing and retrieving in the warehouse, piping components such as pipe, fittings, flanges, and valves are color coded.All most all company has their own color coding system. Sheet metal forming is the most cost-effective forming procedure today for manufacturing parts at large quantities. Pipe insulation is also considered part of the piping system. 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. We will mail out GCAP’s Videos free of charge. 1 Guidelines for Identification of Ammonia Refrigeration Piping and System Components INTRODUCTION Uniform guidelines for identifying ammonia refrigeration piping. Chapter 1 - Piping Size. HPL, SCL, CD, TSS, TSR, LIC, and IPL, For Services > 70 PSIG witch will include the following labels: One alternative for insulating ammonia lines and storage vessels is an insulation system consisting of extruded polystyrene in conjunction with polyvinylidene chloride (PVDC) vapor-retarding film and tape. IIAR Bulletin 114 is considered the most relevant general RAGAGEP. Less Expensive - Ammonia refrigerators require narrower piping, which is less expensive to make.
