API Spec 14L-2020 pdf download.Lock Mandrels and Landing Nipples.
1 Scope This specification provides the requirements for lock mandrels and landing nipples within the production/injection conduit for the installation of flow control or other equipment used in the petroleum and natural gas industries. It includes the interface connections to the flow control device or other equipment, but does not cover flow control devices, the connections to the well conduit, alternate technologies, or other requirements covered by other existing API or ISO specifications 2 Normative References The following referenced documents are indispensable for the application of this document.

3.1 ambient temperature Prevailing temperature at test site. 3.2 compound Combination of constituent elements of the formulation of a nonmetallic material from a supplier. 3.3 control fluid redirection Feature, when activated, that provides control system communication. 3.4 design acceptance criteria Defined limits placed on characteristics of materials, products, or services established by the organization, customer, and/or applicable specifications to achieve conformity to the product design. 3.5 design margin Ratio of the material yield stress divided by the actual design stress in a given component. NOTE Design margins account for a level of reduced performance capability to compensate for uncertainties in the potential loading (applied stress) and the intrinsic variations in the mechanical properties, such as yield strength, ultimate strength, endurance strength, and modulus of elasticity, that have distribution about their mean values. 3.6 design validation Process of proving a design by testing to demonstrate conformity of the product to design requirements. 3.7 design verification Process of examining the result of a given design or development activity to determine conformity with specified requirements. 3.8 flow control device Installed interfacing accessory devices providing flow control unctionality through the lock mandrel. NOTE Examples include, but are not limited to, check valves, instrument hangers, equalizing devices, blanking plugs, and pump-through devices. 3.9 high-pressure, high-temperature equipment HPHT Equipment assigned a pressure rating greater than 1 03.4 MPa (1 5,000 psig) or a temperature rating greater than 1 76.7 °C (350 °F).
