What Is a Drilling Spool?

A drilling spool is a pressure-containing component installed between the blowout preventer (BOP) and the wellhead. It features side outlets that allow the attachment of valves or choke manifolds to circulate drilling fluids and control well pressure, helping to prevent blowouts during drilling operations.

Our drilling spools are ruggedly constructed and precision-engineered to provide a secure connection point for critical well control equipment. They are essential for safe mud circulation and are compatible with various BOPs and diverter systems used in onshore and offshore environments.
