A low-temperature resistant pipeline installation structure

Abstract

This utility model provides a low-temperature resistant pipeline installation structure, relating to the field of pipeline installation technology. It includes a double-pipe assembly consisting of an inner pipe and an adapter connection assembly. The adapter connection assembly consists of an adapter pipe disposed between two outer pipes. Fixed sleeves are provided on both sides of the adapter pipe, and reinforcing ribs are provided between the two fixed sleeves. The reinforcing ribs are arranged in a ring, and the included angle between adjacent reinforcing ribs is equal. The adapter pipe connects the two outer pipes, and the fixed sleeves are fastened to the outer pipes by threads. The ring-shaped reinforcing ribs enhance structural rigidity, ensuring uniform stress on the adapter pipe. During installation, the reinforcing ribs distribute the tightening torque, preventing localized deformation. In low-temperature environments, its symmetrical structure balances thermal stress, preventing cracking at the connection. The ring-shaped layout of the reinforcing ribs also suppresses pipeline vibration, improves fatigue resistance, ensures reliable connection under complex working conditions such as low temperature and vibration, and extends the service life of the pipeline.
