Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe joint technology, and in particular to a thermal insulation pipe joint. Background Technology

[0002] Insulated pipe joints are suitable for connecting insulated pipes in fields such as centralized heating, air conditioning and refrigeration, and chemical fluid transportation. Through a multi-layer insulation and sealing structure, they achieve low thermal conductivity and high sealing performance, solving the problems of large heat loss, easy leakage, complex installation, and poor weather resistance of traditional joints, and meeting the long-term use requirements of complex environments such as underground and overhead installations.

[0003] Existing joints have poor sealing stability during use. When liquid is transported through the pipes at both ends for a long time, vibration will occur. During long-term use, the connection may become loose. In addition, the pipe connection is prone to deformation during thermal expansion and contraction, which leads to reduced stability. Therefore, we have proposed an insulated pipe joint. Utility Model Content
