Casing systems
Casing sections, casing shoes and connection components work as one assembly. Compare the mating interfaces and drawings to identify the replacement part.
Follow the load path through the casing.
| Assembly | Function in the system | Interface that must agree |
|---|---|---|
| Casing drive adapter | Transfers the rig connection to the casing | Drive connection and casing joint |
| Tube section | Forms the casing string and supports the bore | Mating joint, section dimensions and clear internal passage |
| Connection components | Locate and secure adjacent sections | Thread, taper, drive form and seating geometry |
| Casing shoe | Carries the teeth at the casing toe | Tube attachment and inner/outer cutting envelope |
Identify the connection by its complete reference.
The BRV connection references differ in drive form and illustrated geometry. Keep the slash suffixes: BRV75/38LV, BRV75/38LV/4 and BRV75/38LV/4/29 are separate catalogue references.
BRV75/38LV
Hexagonal drive, SW27. Compare the drive shape and the remaining joint dimensions with the installed connection.
Request this configuration
BRV75/38LV/4
Square drive, SW26. This square-drive reference differs from the SW27 hexagonal version.
Request this configuration
BRV75/38LV/4/29
Square drive, SW29. Keep the /29 suffix when ordering to distinguish it from the SW26 square-drive version.

A close fit is not a verified joint.
Identify the mating surfaces.
Photograph the connection from the side and end, including the drive recess, thread and seat. Compare the removed component with the joint it belongs to. A diameter alone cannot identify taper, thread form or the load-bearing contact surface.
Inspect after cleaning.
Wear, packed fines and damaged edges can obscure the original geometry. Check engagement, seating and visible damage before combining new components with worn joints. Keep the component reference with the section or joint drawing used for acceptance.
The supplied brochures list connection components but do not define a universal fit across casing brands. Tube and joint dimensions are selected for the specific assembly.
PRODUCT & PROJECT ENQUIRY
Match components across the complete casing string.
Include the existing casing reference, tube dimensions, joint drawing and the required connection-component references. Add quantities for sections, shoes and wear parts separately.
Tube, shoe and connection.
Match the casing dimensions and connection to the existing system. Include the required length and shoe arrangement when requesting a quotation.
