BREAK DOWN LIST
PIPING SYSTEMS FOR ANHYDROUS AMMONIA
Piping for anhydrous ammonia systems should be extra heavy (Schedule 80) carbon steel when threaded joints are used. Standard weight (Schedule 40) carbon steel may be used when joints are either welded or joined by welding type flanges. Teflon tape along with Gas-Oil Pipe Thread Sealer have been used successfully as a pipe thread lubricant and sealer and is highly recommended.
All piping should be well supported and provisions should be made to protect the piping against the effects of expansion, contraction, jarring, vibration, settling and external corrosion. All fittings should be forged steel; non-malleable metals must not be used. Unions should be of the ground joint type. Some unions have brass seats which must not be used.
PIPING SYSTEMS FOR ANHYDROUS AMMONIA
All piping should be tested for leaks after assembly by introducing ammonia vapor.
Do not introduce liquid ammonia initially because, if it is necessary to disassemble the piping to repair the leak, excessive bleed down time will be necessary. Refer to the section covering ammonia leaks. Wherever there is the possibility of liquid ammonia being trapped between two valves, provisions must be made to include a hydrostatic relief valve to protect the section of isolated pipe and valve. Rubber hoses should never be used in permanent installations. Use only all steel gauges and valves made for ammonia service.
All piping shall be supported to prevent damage to the pipes. Provisions shall be made for expansion, contraction, jarring, vibration, and settling. All refrigeration system piping shall conform to the Refrigeration piping Code (ANSI B31.5) as it applies to anhydrous ammonia.
STANDART LIMITATIONS
The maximum design pressure of the tanks covered by this European Standard is limited to 500 mbarg. For higher pressures, reference can be made to EN 13445.

• API 0620 Design and Construction of Large, Welded, Low-PressureStorage Tanks
SAFETY RELIEF DEVICES Every container used in systems without permanent supply piping to
another source of excess pressure shall be protected from excess pressure by one or more pressure relief valves of the spring loaded type conforming with applicable requirements of ASME UG-125(c)(3); UL-132, “Standard on Safety Relief Valves for Anhydrous Ammonia and LP Gas”, or other equivalent pressure relief valve standard.
Pressure relief valves shall be in direct communication with the vapor space of the container. All pressure relief discharge openings shall have suitable rain caps that will allow free discharge of the vapor and prevent the entrance of water. Provision shall be made for draining condensate that may accumulate.
The discharge from pressure relief valves shall be vented away from the container, upward, and unobstructed to the atmosphere.
MATERIAL SELECTIONIn accordance with API 620 App.R For Double Containment with two metallic walls
