Abstract
A connection flange for tubular members is formed as a separate member having a sealing surface formed on the connection flange for sealingly engaging a complementary mating surface, a formed annulus for receiving an end of a tubular member and a radially extending web having openings to enable threaded fasteners to force the flange sealing surface into sealing engagement with the complementary mating surface. A tubular member is sealingly affixed to the formed annulus by welding. The flange is formed of a relatively thicker material than the tubular member to which it is affixed to provide material and weight savings by enabling the tubular member to be formed of a relatively thin, light weight material.
