Lubricators
A lubricator is a straight pipe with special interface form at both ends,installed between a stripper and the BOPs for CTU operations, used to seal the downhole pressure when lifting and lowering the downhole tool string.
Selection Notes for Lubricators
Lubricators should be reviewed against the actual operating duty and supporting equipment, not only the model name. Confirm pressure class, bore or connection interface, valve arrangement, material compatibility and test-document requirements before quotation.
Application Fit
When reviewing Lubricators, the relevant application discussions include fracturing, well testing, drilling-fluid routing and high-pressure wellhead service. The final application fit depends on the project specification, operating envelope and local requirements. Request the current technical file for Lubricators and confirm operating duty, interfaces, power source, transport format and inspection requirements. The product image is a visual reference; final selection should follow the project configuration and operating envelope.
Inquiry Data for Lubricators
- Working pressure, bore size and required fluid-control rating.
- Manifold layout, valve arrangement, outlet count and remote-operation needs.
- Material compatibility, fluid type, temperature and corrosion exposure.
- Wellhead, fracturing, drilling-fluid or testing-system connection details.
- Required instrumentation, test pressure, inspection agency and documentation.
- General arrangement, pressure class, test records and spare-valve requirements.
Engineering Review and Delivery Scope
Before the equipment package is confirmed, the buyer and supplier should align the configuration, interfaces, inspection scope, documentation package, spare-parts requirements, commissioning responsibilities and after-sales communication route for Lubricators. A quotation should be evaluated against those details, not only against the headline product name.
For Lubricators, send the operating conditions and available tender documents through the inquiry form. When contacting SJ about Lubricators, include operating conditions, required interfaces, delivery format and document scope. This allows the engineering team to identify the available drawings, parameter sheets and inspection documents for the configuration under review.
