<p>PIPE TERMINATION By: Craig Weems and John Coburn A pipe termination, and method of making it, comprised of a tubular metal sleeve insert having one end welded to a terminating flange and having an annular slot in its midregion that is filled with a heat retardant material. This subassembly is coated with a baked plastic material that extends continuously from the connecting face of the flange, through the metal insert and over the opposite end. The subassembly is inserted within the end of a pipe and the pipe end and innermost end of the flange butt each other immediately above the heat retardant material on the insert. The pipe and flange are welded together at their butting regions and the heat retardant material prevents the baked coating on the insert from burning.</p> |
