API - SPEC 19CI
Downhole Chemical Injection Devices and Related Equipment
|Publication Date:||1 June 2019|
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 19G2 and API 19G3).
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.
