Pipe connection assembly

Abstract

A connector assembly is provided for connecting two pipes of dissimilar material. In particular, an assembly is provided for connecting a first end portion of a first pipe to a second end portion of a second pipe formed as a bell housing having a larger inside diameter than an outside diameter of the first end portion and which second end portion overlaps the first end portion. The connector assembly includes a mandrill for attachment to the first end portion, which is formed as a flange extending radially from an outside circumference of the first end portion to face at least a portion of an end face of the bell housing, and an axial tubular extension extending from the flange so as to, upon assembly, reach a point approximately equal to an axial end point of the first pipe, and reside within the second end portion creating an annular space therebetween. A sealing gasket, formed of an electrically insulating material, is formed as a base in the form of a tubular collar for residing fittingly around an outside circumference of the first end portion, and at least one annular fin projecting radially from an outside circumference of the base at an angle with respect thereto, said fin being rotatable inwardly about said angle towards the base and being biased outwardly about said angle, and said fin being substantially inflexible along its radial width.
