Standard notation for flange specifications

Thread Content

According to ASME B16.5 standards, for flanges, is the standard notation NPS1.CL150 or DN25,CL150? Which of these two notations is more standardized? I just mean more standardized.

Either is fine; the nominal diameter is within 16.5, and both metric and imperial units are available, so either one can be used

Both metric and imperial notation are acceptable. The imperial system uses inches plus pound grades.

Either one is fine. . There’s nothing to worry about
