API Spec 19CI-2019 pdf free download.Downhole Chemical Injection Devices and Related Equipment.
1 Scope This specification provides requirements for chemical injection devices intended for use in the worldwide petroleum and natural gas industry. This includes requirements for specifying, selecting, design verification, validation testing, manufacturing, quality-control, testing, and preparation for shipping of chemical injection devices as defined herein. These requirements include in-line debris screen systems, single-use shearable/ frangible devices, and performance testing and calibration procedures. The installation and retrieval of chemical Injection devices and systems is outside the scope of this document (see API 1 9G2 and API 1 9G3). This document does not include requirements for mandrels, carriers, running, pulling, and kick-over tools, handling tools and latches, injection lines, fittings, control line connectors, clamps, chemicals and chemical delivery systems. Service, repair or redress of used chemical Injection devices is outside of the scope of this document. Validation and functional testing within this specification is performed using water as the testing medium. Design validation in conformance with this specification may not provide assurance that a chemical injection device/ product will perform in a specific well, due to the variety and potential contamination of the injected chemicals. Included in this specification are Annex B through Annex G (normative) and Annex A and Annex H (informative). If a product is supplied bearing the API Monogram and manufactured at a facility licensed by API, the provisions of Annex A apply. 2 Normative References The following referenced documents are referred to in the text in such a way that some or all the content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including amendments) applies.
3 Terms, Definitions, Abbreviations, and Acronyms For the purposes of this document, the terms and definitions given in API Q1 (for quality-system-related terms not given below) and the following apply. 3.1 Terms and Definitions 3.1.1 ambient temperature Prevailing temperature at the testing facility. 3.1.2 back check test BCT Static pressure test conducted where pressure is applied to a non-return (check) valve in the reverse direction to normal forward flow. 3.1.3 back pressure Pressure opposing forward flow. 3.1.4 back pressure retention BPR A device providing back pressure support (U-tube prevention) to prevent hydrostatic-fall-through of fluids while allowing flow to a defined outlet. 3.1.5 certificate of conformance Document in which the supplier/manufacturer certifies that the product or service is in conformance to the referenced standards, specifications, and requirements. 3.1.6 chemical delivery system A system above the tubing hanger designed to supply the controlled delivery of chemicals into a well. 3.1.7 chemical injection device/product A downhole, below-the-tubing-hanger device that controls the flow of chemical(s) into a well. 3.1.8 chemicals Fluids injected into the well via a chemical injection system.
3.1.12 crack-open pressure The pressure at which flow of the fluid is initiated in the flow direction as injection pressure is increased. 3.1.13 design validation Process of proving a design by testing to demonstrate conformity of the product to design requirements. NOTE Design validation can include one or more of the following (this is not an all-inclusive list): — prototype tests; — functional or operational tests of production products, or both; — tests specified by industry standards or regulatory requirements, or both; — field performance tests and reviews. 3.1.14 design verification Process of examining the result of a design and development output to determine conformity with specified requirements. NOTE Design verification activities can include one or more of the following (this is not an all-inclusive list): a) b) c) confirming the accuracy of design results through the performance of alternative calculations; review of design output documents independent of activities of design and development; comparing new designs to similar proven designs. 3.1.15 device Component or subassembly which provides a function defined in Table 6.
