This specification has been developed by users/purchasers and suppliers/manufacturers of plunger lift lubricators intended for use in the petroleum and natural gas industry worldwide. This specification is intended to give requirements and information to both parties in the selection, manufacture, testing and use of plunger lift lubricators. Further, this specification addresses supplier/manufacturer requirements which set the minimum requirements with which suppliers/manufacturers shall conform.
This specification has been structured to allow for grades of increased requirements both in quality control and design validation. These variations allow the user/purchaser to select the grade required for a specific application for a chosen tool.
The quality grades and design validation grades provide the user/purchaser the choice of requirements to meet a specific preference or application. Additional quality and design validation requirements may be specified by the user/ purchaser as supplemental requirements.
Plunger Lift Lubricators and Related Equipment
This specification provides requirements and guidelines for plunger lift lubricators, which includes plunger catchers as defined herein for use in the petroleum and natural gas industry. Threaded and flanged external connections are covered by the applicable API or proprietary connection design requirements. This specification provides requirements for the functional specification and technical specification, including design requirements (outlet locations, specified and optional), design extensions, design verification and validation, welding, materials, quality controls (QCs), marking, documentation and data control, shipment, and storage.
This specification does not include control system components, including electrical and electronic devices, installation requirements, field modifications of lubricators, and plunger lift downhole equipment. Additionally, the requirements for the inlet and outlet flange bolting and gaskets are not addressed herein. Equipment and technology that are covered by other API specifications and standards are exempted from this specification.
