3. REQUIREMENTS
3.1 Design and construction. The surge suppressor shall incorporate a diaphragm-type bellows
or piston assembly within a pressurized housing to absorb surge pressure encountered in pipelines.
Nitrogen shall be used for pressurization of the housing. The bellows or piston assembly and the
housing shall be designed to permit the required expansion or compression of the bellows or
movement of the piston within the housing.
3.1.1 Hydrostatic pressure. The bellows or piston assembly shall be capable of withstanding a
hydrostatic pressure of 150 psig against a gas pressure of 52 psig within the surge suppressor
housing. The housing shall be capable of withstanding a hydrostatic pressure of 300 psig.
3.1.2 Gas Capacity. The minimum gas capacity of the housing, with the bellows assembly or
piston completely retracted, shall be 738 cubic inches.
3.1.3 Mounting. The surge suppressor shall be supported by mounting legs of sufficient length to
allow clearance for attachment of hoses and to provide clearance for access to view the pressure
gage and the nitrogen charging valve. The configuration of the mounting legs attached to the
housing shall be optimized for in-service use, maintenance, and inspection by military personnel in
chemical warfare clothing. Mounting legs shall be made of compatible material with the housing
to allow welding for permanent attachment in new equipment installation. Support legs and
attaching hardware, as required, shall be delivered as separate items for surge suppresser's
furnished as replacement items.
3.1.4 Interface connection. The surge suppressor shall include an interface connection device to
allow for nitrogen charging and pressure regulation.
3.1.5 Pressure gage. A pressure gage with a protective cover, with a range to 160 psi shall be
included. The pressure gage shall be of sufficient size to be able to be read from a distance of
three feet or more by a person wearing a protective chemical mask.
