ASME B16.11 Tee ASME B16.11 also provides specifications for forged steel caps, which are fittings used in piping systems to close the end of a pipe. These caps are available in both socket-weld and threaded configurations. ASME B16.11 is one of several standards that cover different types of forged steel fittings used in piping systems. Engineers and designers should refer to the specific standard applicable to their project and follow the guidelines relevant to the intended application.
