ABSTRACT:
An adapter union is disclosed which is especially useful for installation by butt welding on containers for fluids to permit a conduit of smaller internal diameter to be removably attached thereto, and also for certain other specialized uses described herein. The adapter union includes an improved butt weld adapter member. When desired, the adapter member may be installed on containers for fluids by butt welding to thereby permit a conduit of smaller diameter to be attached directly thereto. The disclosure further relates to containers for fluids having the adapter union and/or the adapter member installed thereon. When the adapter union is installed properly, the resultant structure provides for permanency of the installation when desired, and also allows future changes and modifications to be made easily and without damaging the adapter union and/or conduits or other cooperating apparatus attached thereto.
