3.1.4 adapter pressure-containing piece of equipment having end connections of different nominal sizes and/or pressure ratings, used to connect other pieces of equipment of different nominal sizes and/or pressure ratings 3.1.5 annular pack-off mechanism that seals off annular pressure between the outside diameter of a suspended tubular member or hanger and the inside diameter of the head or spool through which the tubular member passes or hanger is suspended 3.1.6 as-shipped condition condition of the product or equipment when it is ready for shipment 3.1.7 back-pressure valve unidirectional or bidirectional check valve that is installed through the christmas tree, into the tubing hanger, and prevents well fluids from flowing out of the well 3.1.8 blind flange flange with no centre bore, used to close off completely a flanged end or outlet connection 3.1.9 body any portion of wellhead and christmas tree equipment between end connections, with or without internal parts, which contains well-bore pressure 3.1.10 bonnet pressure-containing closure for a body, other than an end or outlet connection 3.1.11 bottom casing pack-off mechanism that seals off annular pressure between the outside diameter of a suspended tubular member or hanger and the inside diameter of the spool or tubing-head adapter placed over the suspended tubular or hanger 3.1.12 bullplug pressure-containing closure for a female-threaded end or outlet connection, which may have an internal counter- bore and/or test port 3.1.13 calibration comparison and adjustment to a standard of known accuracy 3.1.14 carbon steel alloy of carbon and iron containing a maximum of 2 % mass fraction carbon, 1,65 % mass fraction manganese, and residual quantities of other elements, except those intentionally added in specific quantities for deoxidation (usually silicon and/or aluminium)
3.1.41 equivalent round ER standard for comparing various shaped sections to round bars, in determining the response to hardening characteristics when heat-treating low-alloy and martensitic corrosion-resistant steel 3.1.42 exposed bolting bolting that is exposed directly to the sour environment or that is buried, insulated, equipped with flange protectors, or otherwise denied direct atmospheric exposure 3.1.43 fabrication weld weld joining two or more parts 3.1.44 fit geometric relationship between parts 3.1.45 flange protruding rim with holes to accept bolts and having a sealing mechanism used to join pressure-containing equipment, with dimensions specified in this International Standard 3.1.46 forge, verb deform metal plastically into desired shapes with compressive force NOTE Forging is usually a hot process. The use of dies is optional. 3.1.47 forging, noun shaped metal part formed by the forging method 3.1.48 form essential shape of a product including all its component parts 3.1.49 full-bore valve valve whose closure mechanism has a bore dimension the same as or larger than the valve body 3.1.50 function operation of a product during service 3.1.51 gate valve valve assembly with a gate operating within the body, 90° to the conduit, to effect a closure 3.1.52 hanger mandrel portion of a casing or tubing hanger that is attached by a threaded connection to the tubular string and forms the upper end of that tubular string
3.1.54 heat-treat lot 〈batch furnaces〉 material placed on loading or carry devices and moved as a batch through one heat treat cycle 3.1.55 heat-treat lot 〈continuous furnaces〉 group of pieces of material with the same nominal size that is moved sequentially through the heat treatment process using the same process parameters 3.1.56 heat treatment heat treating specified, timed sequence of controlled heating and cooling of materials for the purpose of changing physical or mechanical properties 3.1.57 heat-affected zone HAZ portion of the base metal that has not been melted, but whose mechanical properties or microstructure has been altered by the heat of welding or cutting 3.1.58 heat-sensitive lock-open device device installed on a surface safety valve (SSV) actuator to maintain the SSV valve in a full open position until exposed to sufficient heat to cause the device to release and allow the SSV valve to close 3.1.59 hold period period of time that the product is subjected to pressure and isolated from the pressure source 3.1.60 hot isostatic pressing HIP special forming process used to compact and metallurgically bond metal powder NOTE This process takes place within a flexible, metal container whose contents are formed into the desired shape by subjecting the container to high temperature and pressure in an autoclave. It produces a fully wrought structure. 3.1.61 hot-work deform metal plastically at a temperature above the recrystallization temperature 3.1.62 job-lot traceability ability to trace parts as originating from a job lot that identifies the included heat(s)
