All refrigerated piping shall conform to the Refrigeration Piping Code, American National Standards Institute, B31.5-1966 with addenda B31.1a-1968, which is incorporated by reference as specified in § 1910.6, as it applies to ammonia. This is true for both the condensing unit capacities on the individual specification sheets or the separate suction line sizing DX AMMONIA PIPING HANDBOOK Bruce I. Nelson, P.E. Piping Design Basics Good piping design results in a balance between the initial cost, pressure drop, and system reliability. Hope it will be useful to new entrants as well as professionals alike. The Provided specifications and plans are for use by the Prime contractor and his subcontractors. The tests shall be made on new or repaired equipment and piping. Inspection and Maintenance of Ammonia Mechanical Refrigerating Systems • ANSI/IIAR Standard 2 Equipment, Design, and Installation of Ammonia Mechanical Refrigerating Systems • ANSI/ASME B31.3 Process Piping • ANSI/ASME B31.5 Refrigeration Piping and Heat Transfer Components • ANSI/NBIC-23 NBBI 2001 National Board Inspection Code PT&P manufactured multiple pre-insulated pipe supports for cryogenic temperatures in an ammonia plant in Louisiana. Carbon steel transitions or fittings may be used where required to connect to valves, vessels or similar components. This book is a guide to modern ammonia refrigeration piping, a comprehensive introduction to ammonia piping as it is practiced in the field. Standard specification for piping fittings of wrought carbon steel and alloy steel for low-temperature service. Refrigerant velocities in vertical lines should be at least 1500 ft/min to ensure good oil return; After the steam is used it is then dumped to the main condenser. These cryogenic pipe supports, also known as “cold shoes” are designed with 2” thick polyurethane and foam glass for insulation and fabricated from galvanized steel for the shoe, with alloy bolts and nuts.They are 2” diameter 14″ L X 4″ W X 6″ H. Each batch is tested for strength, color, and clarity. 1 Guidelines for Identification of Ammonia Refrigeration Piping and System Components INTRODUCTION Uniform guidelines for identifying ammonia refrigeration piping. Liquid lines 1.5 inches and smaller shall be not less than Schedule 80 carbon steel pipe. Installation Details. 5.2.6. Guideline for Developing an Energy Control Plan for Manual Hand Valves in Ammonia Refrigeration Systems, 1st Edition. Bulletin 114 has for over 20 years focused on correct labeling of pipe and equipment in an industrial ammonia refrigeration system. The initial cost is impacted by the diameter and layout of the piping. Because In the steam drum the feed water is then turned into steam from the heat. Sr. Download PDF. Piping & Valves: 5.2.6.1. Aqua Ammonia (Ammonium Hydroxide) is a water solution of ammonia, and assay is determined by weight of ammonia in water. Standard Practice for Ammonia Colorimetric Leak Testing: E1603 / E1603M - 11(2017) Standard Practice for Leakage Measurement Using the Mass Spectrometer Leak Detector or Residual Gas Analyzer in the Hood Mode: E2024 / E2024M - 11(2019) Standard Practice for Atmospheric Leaks Using a Thermal Conductivity Leak Detector: E2930 - 13 Standard specification for wrought austenitic stainless steel piping fittings. Ammonia is a natural refrigerant that has been used for many years in a variety of applications due to its high thermal efficiency. It provides the appropriate selection, specification and material grade of pipe and piping components for a given service.
