NOTE See ASQ Z1.4 or ISO 2859-1 for examples.
3.1.4 articulated choke and kill line A choke and kill line assembled as a unit, with rigid pipe, swivel unions and end connections, designed to accommodate specified relative movement between end terminations. NOTE Articulated lines used for purposes other than choke and kill lines are outside the scope of this document. 3.1.5 blind flange A flange with no center bore, used to close off completely a flanged end or outlet connection. 3.1.6 body Any portion of API equipment between end connections, with or without internal parts, that contains well bore pressure. 3.1.7 bonnet A pressure-containing closure for a body, other than an end or outlet connection. 3.1.8 buffer chamber A chamber installed downstream of the chokes to allow manifolding of the bleed lines together. 3.1.9 calibration Comparison and adjustment to a standard of known accuracy. 3.1.10 casting (noun) An object at or near finished shape obtained by solidification of a substance in a mold. 3.1.11 casting (verb) Pouring molten metal into a mold to produce an object of desired shape. 3.1.12 check valve A valve that permits fluid to flow freely in one direction and contains a mechanism to automatically prevent flow in the other direction. 3.1.13 chemical analysis Determination of the chemical composition of material. 3.1.14 choke Equipment used to restrict and control the flow of fluids. 3.1.15 choke/kill line A high-pressure line that allows fluids to be pumped into or removed from the well with the BOPs closed.
3.1.16 choke/kill manifold An assembly of valves, chokes, gauges, and lines used to control the rate of flow and pressure from the well when the BOPs are closed. 3.1.17 closure bolting Threaded fasteners (studs, nuts, bolts, and cap screws) used to assemble pressure-containing parts or join end or outlet connections. 3.1.18 flow bean The replaceable orifice part used in positive chokes to control flow rates. 3.1.19 conformance Compliance with specified requirements. 3.1.20 carbon steel An alloy of carbon and iron containing a maximum of 2 % carbon, 1.65 % manganese, and residual quantities of other elements, except those intentionally added in specific quantities for deoxidation (usually silicon and/or aluminum). 3.1.21 corrosion resistant alloys CRA Nonferrous-based alloys where any one or the sum of the specified amount of the elements titanium, nickel, cobalt, chromium, and molybdenum exceeds 50 % mass fraction. NOTE This definition is different from that in NACE MR0175/ISO 15156. 3.1.22 corrosion resistant ring groove Ring grooves lined with corrosion resistant alloy or an austenitic stainless steel to resist metal loss corrosion. 3.1.23 date of manufacture The date of the manufacturer’s final acceptance of finished equipment. 3.1.24 end fitting End assembly containing a flexible termination and end connection used on choke and kill lines. 3.1.25 end and outlet connection Integral threads and flanges, hubs, unions, or other end connectors used to join together equipment that contains or controls pressure. 3.1.26 end termination Part of the end fitting that forms the transition between the flexible line construction and the end connector.
