Description
Product Description ANSI/ASME B16.9 Tee
ASME B16.9 is a standard developed by the American Society of Mechanical Engineers (ASME) for the design and manufacture of butt-welding fittings. Specifically, ASME B16.9 Tee refers to a type of pipe fitting that is used to join three sections of pipe together, typically at a right angle. It is designed to provide a “T” shape to allow flow from the main line to a branch pipe.
