The Unsung Heroes of Drilling : Crossover Subs
A crossover sub is a mechanical component that utilises threaded connections to link components of varying sizes or thread types. These vital components are found throughout the drill strings, particularly between drill pipes and drill collars, allowing drillers to modify installations according to specific field conditions.
Uses of Crossover Subs
Crossover subs link drill pipes to collars through their specifically developed threaded connection systems and box features. The thread patterns of crossover sub-ends match those of the components that need connection. Drilling rigs operate multiple crossover subs, which their operators use according to requirements.
The threaded connections have a phosphate coating that keeps them from galling during installation and also keeps them from rusting. Manufacturers construct all subs based on established specifications.
Importance of Crossover Subs
Every drilling operation needs crossover subs because they allow drill strings to customise themselves to suit well requirements. Drilling operations succeed due to crossover subs, which fix broken components while linking different parts of the drill string to guarantee operational safety.
The fluid circulation system of crossover circulating subs utilises either side or inline ports for assisting with fluid movement. Manufacturers create side or inline ports using heat-treated steel components that satisfy safety standards.
Types and Configurations
Crossover subs are available in three different configurations:
The installation of these components enables a transition between different connections while simultaneously protecting high-value drill stem components, thus providing economic benefits.
Standard and Premium Options
Quality manufacturers offer both standard and premium connection crossover subs to their customers. Such short subassemblies function as vital connectors for elements that have separate dimensions or dissimilar thread patterns.
The crossover product line spans from 2 3/8 inches to 20 inches in a wide selection of connection options but can provide custom crossover subs through special orders. Please feel free to reach out to us for a quote on crossover subs tailored to your specific drilling needs.
