Abstract
Systems and methods for making connections between pipe sections. In one embodiment, a pipe connection consists of a pair of flanges having conically tapered sealing surfaces and a tapered seal ring. A first one of the flanges has a male nose extending forward from the face of the flange, while a second one of the flanges has a female pocket which is recessed into the flange. The seal ring has conically tapered surfaces complementary to those of the flanges so that, when the connection is assembled, a seal is created between the seal ring and each of the flanges. The nose of the male flange extends forward so that, when the connection is assembled, the nose makes direct contact with the pocket of the second flange, forming a substantially gap-free conduit through the flanges.
