Telescoping Union
Telescoping Union is a pipe connection device that adjusts pipe length through a telescopic sleeve structure, suitable for scenarios requiring thermal expansion and contraction or displacement compensation. Its core structure includes a male connector, a female connector, a union, and a pipe string. Length adjustment is achieved by the axial sliding of the pipe string within the female connector.
Core Functions:
Telescopic Adjustment: The pipe string slides freely along the axial direction, compensating for length changes in the pipeline due to temperature variations or external forces, preventing stress concentration or leakage caused by expansion or contraction.
Sealing Design: An O-ring is installed in a sealing groove on the outer wall of the pipe string, ensuring a tight seal between the pipe string and the inner wall of the female connector during expansion and contraction.
Quick Installation: Connection can be completed without complex tools; the union's internal thread connects to the female connector's external thread.
Application Scenarios:This device is widely used in industrial pipeline systems (such as oilfield drilling equipment and chemical production facilities), energy transmission pipelines, and other scenarios requiring displacement compensation. It features a compact structure and convenient maintenance.
