发明名称 FORMED GAS METER CONDUIT
摘要 The disclosure relates to a formed conduit for supporting natural gas meters having fittings defined thereon, and the method of making the same. The conduit, while in a linear tubular configuration, is formed at one end by a forging or swaging operation wherein an outwardly extending radial flange is defined thereon of the material of the conduit, and other desired configurations may be formed on the forged end, such as gasket receiving and sealing surfaces and the like. After forging the conduit is bent to a final configuration wherein the shaped end is usually bent back toward the central region of the conduit wherein the axis of the shaped end is disposed parallel to and spaced from the axis of the conduit central region, which is ultimately mounted on a supporting bracket.
