According to "ASME B16.47 flange" pressure levels were
divided into the following categories:
"ASME
B16.47 flange" threaded connection points (wire tapping) flange and
welding flange. Low pressure small diameter wire flange, high pressure and low
pressure are the use of large-diameter welded flange thickness and bolt diameter
and the number of different connection flange pressures are
different.
Depending on the level of stress, "ASME B16.47
flange" pad there are different materials, from low pressure asbestos
gasket, asbestos mat high pressure to the metal pad has.
1. Material
classified carbon steel, cast steel, alloy steel, stainless steel, copper,
aluminum, plastic, argon and so on.
