Coupling concrete pipes are reinforced concrete pipes connected by tenon and mortise structures at the pipe ends. This contact method allows for the transfer of loads between pipes, thereby enhancing sealing performance. Generally, we use rubber rings for water tightness. The specifications of the coupling pipes also determine whether they serve as the outer casing for pipelines used for water supply, electricity, telecommunications, and other underground installations, or as urban stormwater and sewage drainage pipes. Moreover, these pipes come in different specifications based on their functions.
