The Ammonia Refrigeration Piping Handbook-International Institute of Ammonia Refrigeration 2014-01-01 The Ammonia Refrigeration Piping Handbook has been hailed as one of the best publications ever produced by IIAR. Also included within the scope of this Code are: This Code prescribes requirements for the materials, design, fabrication, assembly, erection, test, and inspection of refrigerant, heat transfer components, and secondary coolant piping for temperatures as low as -320 deg F (-196 deg C), whether erected on the premises or factory assembled, except as specifically excluded in the following paragraphs. A pipe marking system is about more than just meeting regulatory requirements, it also helps to strengthen an overall safety program. The physical state Liquid should be on a yellow rectangle, and Vapor should be on a blue rectangle. The pressure Low should be on a green rectangle, and High should be on a red rectangle. TABLE OF CONTENTS. 2 nd Process condition that will impact the selection of material is the Temperature of fluids. NON-REFRIGERATED SYSTEM PIPING Non-refrigerated ammonia system piping must conform to the ANSI B31.3 and K61.1 standards. Piping for industrial plants and marine applications. This can help alert personnel to prevent forklifts and other machinery from colliding and potentially damaging components of ammonia refrigeration systems.

Graphic Products, Inc. Ammonia Piping Labeling Standards; Color Code For Ammonia Piping; References >> IIAR Ammonia Refrigeration Piping Handbook. If you use ammonia refrigeration piping and system components, it’s crucial that you understand the most recent pipe labeling requirement changes made by the IIAR (International Institute of Ammonia Refrigeration). B31.4 says it does not apply if pipe is above 15 psi (1 bar) gage pressure if design temperature is below minus 20°F (-30°C) or above 250°F (120°C) Welders making welds to anhydrous ammonia system piping must be certified in accordance with ASME code, section IX, and must furnish a current QW-484 qualification form upon request. This guide outlines industry standards, explains different types of pipe marking in the field with visual charts, and solutions to help streamline the labeling process. 3 Scope These guidelines apply to vapor compression refrigeration … IIAR Ammonia Refrigeration Piping Handbook.

Contact. The most common system piping components meeting the minimum standards for non-refrigerated ammonia systems are: PIPE/NIPPLES/FLEXIBLE CONNECTOR SPECIFICATIONS ASTM/API Specification Tensile Strength Schedule Rating Color changes: The background color for Ammonia pipe markers shall be Safety Orange, following the color guidelines by ANSI Z535.1 Safety Color Code. Sensible Heat Ratio, Room rh%, and Evaporator Ratings 14 . Why color coding of piping material?During construction and fabrication, various grades of carbon steel, alloy steel, and stainless steel are used.
