Liquid Oxygen (LOX) Storage and Supply System
**************************************************************************
NOTE: Provide seismic requirements for piping,
tanks and related equipment supports, if a
Government designer is the Engineer of Record, and
show on the drawings. Delete the inappropriate
bracketed phrase. Sections 13080 and 15070,
properly edited, must be enclosed in the contract
documents.
**************************************************************************
LOX storage system and associated equipment shall comply with NFPA 50 and
CGA G-4.4. Tanks, vaporizers and regulators shall be suitable for exterior
installations. Cleaning for components, equipment, valves, piping and
tanks for oxygen service shall be accomplished in accordance with CGA G-4.1,
CGA HB. The system shall be rated to withstand a minimum wind speed of
[_____] km miles per hour, maximum ambient temperature [_____] degrees C F,
minimum ambient temperature [_____] degrees C F, [_____] relative humidity,
and [_____] meters feet mean sea level altitude. System shall be supported
and braced to resist seismic loads [as specified in Sections 13080 SEISMIC
PROTECTION FOR MISCELLANEOUS EQUIPMENT and 15070A SEISMIC PROTECTION FOR
MECHANICAL EQUIPMENT] [as indicated].
2.2.2.1
LOX Storage Tanks
**************************************************************************
NOTE: Typically, 304 stainless steel is used for
LOX inner tanks less than 6000 L (1500 gallons) or
6750 kg (15,000 pounds), while 9 percent nickel
units are generally specified for larger tanks
principally due to economic considerations. Typical
maximum operating pressure for the LOX system will
generally be less than 515 kPa (75 psi); significant
cost savings can be achieved by reducing the tank
pressure requirements, but lower pressure tanks may
require a longer lead time to procure since the
1.2/1.7 MPa (175/250 psi) tanks are most commonly
