Description

Tubing assemblies with anti-slip seals

technical field

The utility model relates to the field of pipe material sealing, in particular to a pipe material assembly with an anti-separation sealing structure.

Background technique

Corrugated pipes are widely used in the field of drainage due to their advantages of good compression resistance, low engineering cost, light weight, and quick and convenient construction. In order to facilitate transportation, the length of each section of corrugated pipe cannot be made too long, and it is connected when it is transported to the construction site for installation. The connection method of the existing bellows is generally a plug-in type or a flange connection type. The plug-in connection method is: install a rubber seal at the second trough of the socket end and apply lubricant, and then insert it directly into the socket, and pay attention that the socket should be against the direction of water flow, and the socket should be in the direction of water flow.
