  • Patent number: 12092220
    Abstract: A sealing system including a first end and a second end with flexible bellows extending therebetween. The first end includes a base plate with an inner ring having an inner diameter. The inner ring is configured to receive a pipe therethrough. The pipe has an outer diameter, which is smaller than the inner diameter of the inner ring. The bellows of the sealing system has a first length in a first position and second length in a second position. Upon axial expansion of the pipe, the bellows is configured to move from the first position to the second position. The sealing system may also comprise a mechanical protective element, such as a shroud which extends around the bellows. Movement of the bellows can be further limited with rods extending from the shroud to a surrounding substrate or a cable fixing a maximum distance between the pipe and the shroud.

The cylindrical socket section of the socket has an inside diameter less than the outside diameter of the cylindrical pin section to form an interference fit that provides the strength of the joint. Sealant is extruded longitudinally and trapped in the tapered annular cavity to prevent leaking.
