Locking Coupling
Locking couplings are precision components used to secure internal drilling assemblies and ensure positive engagement between wireline system components during core drilling operations.
Role in the Core Drilling System
Locking couplings play a vital role in maintaining secure connections within a core drilling system. Installed as part of the internal assembly, they prevent unintentional disengagement of components during drilling and retrieval operations. Proper locking coupling selection ensures system integrity, operational safety, and reliable core recovery.
Product Description
Spenta Engineers manufactures locking couplings designed for dependable performance in wireline core drilling systems. Each locking coupling is engineered to provide secure engagement, precise alignment, and consistent operation when used with compatible head assemblies, overshots, and core barrel components.
Standard Sizes, Lengths & Manufacturing
Locking couplings are manufactured in standard sizes including AQ, BQ, NQ, HQ, and PQ. Components are produced from high-strength alloy steel using precision machining processes. Controlled heat treatment enhances strength, wear resistance, and durability under repeated loading conditions.
