Please note. Any addenda or errata may not be included in translated editions of this standard.

This specification provides requirements for side-pocket mandrels used in the petroleum and natural gas industry. It covers specifying, selecting, designing, manufacturing, quality control, testing, and preparation for shipping of side-pocket mandrels.

This specification addresses standard side-pocket mandrel designs, as well as high-pressure and/or high-temperature (HPHT) equipment rated greater than 103.43 MPa (15,000 psi) and/or greater than 177 °C (350 °F) wellbore conditions as proffered by API 1PER15K-1.

This specification does not address nor include requirements for end connections between the side-pocket mandrels and the well conduit. The installation and retrieval of side-pocket mandrels is outside the scope of this specification. Additionally, this specification does not include specifications for center-set mandrels, mandrels that employ or support tubing-retrievable flow control devices, or side-pocket mandrels that incorporate nonmetallic materials for pressure containment.

This specification does not include gas-lift or any other flow-control valves or devices, latches, and/or associated wire line equipment that can or cannot be covered in other API specifications.

The side-pocket mandrels to which this specification refers are independent devices that can accept installation of flow-control or other devices down-hole. See more
