摘要： The embodiments of the present disclosure provide a system for connecting a mainline pipe with an outlet pipe. The system comprises an outlet pipe configured to be coupled to a mainline pipe near a proximal end of the outlet pipe, a first sleeve disposed on an exterior surface of the outlet pipe and comprising a first lip at a proximal end of the first sleeve, and a second sleeve disposed on the first sleeve and comprising a second lip at a proximal end of the second sleeve. The first lip of the first sleeve may be configured to abut an interior surface of the mainline pipe, and the second lip of the second sleeve may be configured to abut an exterior surface of the mainline pipe.
