Usually used in the industrial piping system with nominal size less than DN100 metal materials forged socket welding and threaded fittings manufacturing.
ASME B16.11: This standard makes a request for pressure-temperature ratings, dimensions, tolerances, standards and materials for socket welding and threaded fittings, and the manufacturer and purchaser can coordinate the fitting of forged rolling materials for special sizes and shapes. The criteria for selecting fittings and materials suitable for use in specific fluids do not fall within this standard range.
