GASKET SPW CR B16.20.175 RF B16.5 CL 150
Thread Content
I have a purchase list that lists it as follows: Specification/Model, Material – DN20, GASKET, SPW CR, B16.20.175, RF, B16.5, CL 150. I deal in gaskets, and I use that standard to look up such information. Please help me
ASME B16.20 wound gasket CL150 t=4.5mm for use with ASME B16.5 RF CL 150 flanges
However, American standards always use inches as the unit of measurement, such as 1/2 or 3\", etc. Its specification is DN20
Of course, the dimensions are determined based on the detailed descriptions, but there is an issue with your description: ASME-B16.20a – Spiral-wound and laminated metal gaskets for pipe flanges; ASME-B16.21 – Non-metallic flat gaskets for pipe flanges; ASME-B16.5 – Pipe flanges and fittings
