3.1.4 design load Sum of the static and dynamic loads that would induce the maximum allowable stress in the equipment. 3.1.5 design safety factor DSF Factor to account for a certain safety margin between the maximum allowable stress and the minimum specified yield strength of the material. 3.1.6 design verification test Test undertaken to validate the integrity of the design calculations used. 3.1.7 drilling liquids Liquid solutions (referred to as mud) conveyed at high pressure through the high-pressure mud piping system, mud standpipe, rotary hose, rotary swivel stem, drill string, and drill bit to accommodate the drilling process. NOTE For the purpose of this specification, drilling liquids do not include fluids containing pressurized air or gasses of any kind. 3.1.8 dynamic load Load applied to the equipment due to acceleration effects. 3.1.9 end connector A fitting located at the end of a hose assembly featuring line pipe threads that allows a hose assembly to be connected to a piping system. EXAMPLE A flange or hub, as specified in API 6A, or a hammer lug union that is butt-welded to, or is manufactured as an integral part of the hose coupling material. NOTE 1 See API 5B for line pipe thread specifications. NOTE 2 See Figure 11. 3.1.10 equivalent round ER Standard for comparing variously shaped sections to round bars, used in determining the response to hardening characteristics when heat treating low-alloy and martensitic corrosion-resistant steels. 3.1.11 hazardous area or zone A location where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings. 3.1.12 high pressure Working pressure values ranging from 10.3 MPa to 103.4 MPa (1500 psi to 15,000 psi). NOTE See Table 9. 3.1.13 high-pressure cement hose A hose used strictly for the conveyance of cement slurries at high pressure.
3.1.14 high-pressure mud hose A rotary hose, vibrator hose, or jumper hose. 3.1.15 hose assembly Consists of hose body and hose coupling. NOTE See Figure 11. 3.1.16 hose body Plain end hose with no hose couplings or end connectors attached. 3.1.17 hose coupling Fitting attached to the ends of the hose body. 3.1.18 hose end connector A fitting located at the end of a hose assembly featuring line pipe threads as specified in API 5B, or for example a flange or hub as specified in API 6A, or hammer lug union, that is butt-welded to or is manufactured as an integral part of the hose coupling material that allows a hose assembly to be connected to a piping system. NOTE See Figure 11. 3.1.19 hose design family Hose assemblies of different internal diameters and working pressures with the same number of reinforcing plies and utilizing the same method of hose coupling attachment and designed to the same design methodology and maximum allowable stress criteria. 3.1.20 identical design concept Property of a family of units whereby all units of the family have similar geometry in the primary load-carrying areas. 3.1.21 jumper hose A flexible hose assembly used to convey high-pressure drilling liquids that is located anywhere in the high- pressure mud piping system between the mud-pump discharge outlet and the mud standpipe manifold on the drill floor to accommodate relative movement between them. 3.1.22 linear indication An indication, revealed by NDE, having a length at least three times its width. 3.1.23 loose gear Off-the-shelf equipment including, but not limited to, shackles, chain, hooks, connecting links, turnbuckles, binders, sheave blocks, and swivels used in an assembly to suspend, secure, or lift a load. 3.1.24 maximum allowable stress Specified minimum yield strength divided by the design safety factor. 3.1.25 maximum working temperature The upper limit of the temperature range specified in 9.6.3.
