Abstract
Systems and methods for coupling pipes made of dissimilar materials in applications that are subject to large variations in temperature. In one embodiment, a connection comprises a first flange made of a first material and a second flange made of a second material. Each flange is designed to be welded to a pipe of the same material. One of the flanges has a male mating surface, while the other flanges as a female mating surface. The male flange is made of the material that experiences greater expansion or less contraction when the temperature of the connection is changed from a connection temperature to an operating temperature. The female flange is made of the other material. A sealing ring having elastic properties is preferably used between the mating surfaces of the flanges.
