BS 10 is a British standard for flanges, which specifies the dimensions and materials of flanges used in piping systems. BS 10 flanges are commonly used in the UK and other countries that follow British standards.
There are several types of BS 10 flanges, including:
Plate Flanges: These flanges are flat and are used to connect pipes or fittings.
Weld Neck Flanges: These flanges have a long tapered hub that provides a smooth transition from the flange to the pipe.
Slip On Flanges: These flanges have a slightly larger diameter than the pipe and are slipped over the pipe end. They are then welded in place.
Blind Flanges: These flanges are used to close off the end of a piping system. They do not have a center hole.
BS 10 flanges are available in different sizes and pressure ratings. The most common materials used for BS 10 flanges are carbon steel, stainless steel, and alloy steel. The standard specifies the dimensions, tolerances, and marking requirements for each type of flange.
