Your facility can/should adopt your own program. 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. requirements applicable to ammonia refrigeration plants. HTRL, HTRS, MRTL, MTRS, HTS, DR, MTS, BS, ES, HSS, For Services within -1 Degrees F to -20 Degrees F (Saturated pressure 3 PSIG вЂ“ 15 PSIG): IIAR updated Bulletin No. The primary article is titled вЂњThe Color Conundrum IIAR Defines Piping ConventionвЂќ and announce to some changes that will be happening to Bulletin 114 that will be re-released in 2014. When yellow became the standard for ammonia pipe labels, they matched the A13.1 standard created by the American National Standards Institute (ANSI). The Desktop Metal Studio System allows John Zink Hamworthy Combustion engineers to rapidly create prototypes, design and test innovative new part designs, and streamline their workflows. The recommended colors in ASME A13.1 are: Since ammonia would be classified with the Toxic and corrosive fluids the appropriate pipe/label color would be ORANGE. Already a member? Ammonia refrigeration systems have traditionally employed evaporators supplied with liquid by either gravity flooding (with surge drums), or pumped overfeed (either with mechanical pumps or discharge gas-driven vessels). They also meet IIAR standards for ammonia refrigeration and pipe identification, and they come in various styles and legends, including Opti-Codeв„ў Medium Temperature and High Temperature Recirculated Suction, SetmarkВ® Low Temp Recirculated Liq, and Ultra-MarkВ® Hot Gas.
