ANVIL® Anvilets provide a strong branch pipe connection, considerably stronger than a welded pipe-to-pipe connection. Consequently, with good welding procedures, ANVIL® Anvilets offer greater resistance to distortion and bursting. ANVIL® Anvilets readily and economically permit the adding of branch connectors to existing piping installations, eliminating the relatively higher cost of cutting or disassembly and re-assembly required for the installation of tees. ANVIL® Anvilets of the same outlet size as a header or run pipe size (i.e. "Full Size" Anvilets) are so proportioned that the (elliptically shaped) hole in the header pipe has the minimum weakening or distortion effect and yet provides good fluid flow characteristics.
