1100.1 Scope
1100.1.1 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 require- ments for the design, materials, construction, assembly, inspection, testing, operation, and maintenance of pip- ing 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 storagefacilities,pipeline terminals, pump stations, and pressure reducing stations, including piping up to the firstvalve of attached auxiliary water lines
(b) slurry piping, storage facilities, and other equip-ment located on property which has been set aside forthe slurry transportation system
(c) those aspects of operation and maintenance ofslurry transportation piping systems relating to thesafety and protection of the general public, operatingcompany personnel,environment,property, and the piping systems [see paras.1100(c) and (d)l
1100.1.2 This Code does not apply to:
(a) auxiliary piping,such as for water, air, steamlubricating oil, gas, and fuel
(b) pressure vessels, heat exchangers, pumps, metersand 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(-3C) or above 250°F (120°C)(d) piping within the battery limits of slurry pro-cessing plants and other non-storage facilities(e) the design and fabrication of proprietary items ofequipment,apparatus, or instruments
11002 Definitions
Some of the terms commonly used in the Code aredefined below.
Accidental loads: any unplanned load or combination ofunplanned loads caused by human intervention or natu-ral phenomena.
breakaua coupling: a component installed in the pipelineto allow the pipeline to separate when a predeterminedaxial load is applied to the coupling
buckle: a condition where the pipeline has undergonesufficient plastic deformation to cause permanent wrin-kling in the pipe wall or excessive cross-sectional defor-mation caused by loads acting alone or in combinationwith hydrostatic pressure.
column buckling: buckling of a beam or pipe under com-pressive axial load in which loads cause unstable lateraldeflection, also referred to as upheaval buckling.
connectors: component, except flanges, used for the pur-pose of mechanically joining two sections of pipe.corrosion: the deterioration of a material, usually a metal,by reaction with its environment.defecf: an imperfection of sufficient magnitude to warrantrejection.
ductile iron: a gray iron base metal to which an innoculantis added to the molten state so that upon solidification,the graphite is present in the form of spheres or nodulesrandomly distributed in a matrix of ferrite. A minimumtensile strength of 60,000 psi (207 MPa) is required.
engineering design: the detailed design developed fromoperating requirements and conforming to Coderequirements, including all necessary drawings andspecifications, governing a piping installation.erosion: destruction of materials by the abrasive actionof moving fluids, usually accelerated by the presence ofsolid particles.
