ASME Pipe Fittings Dimensional

Post category:Code and Standard / PIPING / Piping Standard

To ensure compatibility of piping fittings manufactured by various manufacturers globally, American Society of Mechanical Engineers has devised dimensional standards for various piping fittings. These are the most used dimensional standards in word for piping. They cover various fittings like pipes, tees, elbows, reducers, flanges, crosses and many other fittings. Here is a comprehensive list of such piping dimensional standards.
