Description / Abstract:
Rules for this Code section have been developed considering the needs
for applications, which
include piping transporting aqueous slurries between plants and
terminals and within terminals,
pumping and regulating stations. This Code prescribes requirements for
the design, materials,
construction, assembly, inspection, testing, operation, and
maintenance of piping transporting
aqueous slurries of nonhazardous materials, such as coal, mineral
ores, concentrates, and other
solid materials.
Piping consists of pipe, flanges, bolting, gaskets, valves, relief
devices, fittings, and the
pressure containing parts of other piping components. It also includes
hangers and supports, and
other equipment items necessary to prevent overstressing the pressure
containing parts. It does not
include support structures such as frames of buildings, stanchions, or
foundations, or any
equipment such as defined in para. 1100.1.2(b).
Also included within the scope of this Code are
(a) primary and auxiliary slurry piping at storage facilities,
pipeline terminals, pump stations,
and pressure reducing stations, including piping up to the first valve
of attached auxiliary water
lines
(b) slurry piping, storage facilities, and other equipment located on
property which has been set
aside for the slurry transportation system
(c) those aspects of operation and maintenance of slurry
transportation piping systems relating to
the safety and protection of the general public, operating company
personnel, environment,
property, and the piping systems [see paras. 1100(c) and (d)].
This Code does not apply to:
(a) auxiliary piping, such as for water, air, steam, lubricating oil,
gas, and fuel
(b) pressure vessels, heat exchangers, pumps, meters, and other such
equipment including internal
piping and connections for piping
(c) piping designed for internal pressures
(1) at or below 15 psig [103 kPa (gage)] regardless of temperature
(2) above 15 psig [103 kPa (gage)] if design temperature is below
−20°F (−30°C)
or above 250°F (120°C)
(d ) piping within the battery limits of slurry processing plants and
other non-storage facilities
(e) the design and fabrication of proprietary items of equipment,
apparatus, or instruments
