Seeking expert advice on the specifications of metal wound gaskets and non-asbestos gaskets

Thread Content

Dear experts, our company has received an overseas trade order to purchase gaskets, but the boss says he can’t understand it. Could you please help check what data is missing? DN200, 4.5 MM thickness, spiral wound with graphite filler; inner and outer rings made of SS DSS UNS 32750 duplex steel. Only DN200 is specified here – is the pressure data missing? NB25, 4.5 MM thick. SS 316L with graphite filler; inner and outer rings made of SS316L. It’s a gasket made of 316 stainless steel for both the inner and outer layers. NB25 is in inches, right? It doesn’t seem to have any pressure data either And what standards govern the dimensions of these two types of winding gaskets? Is there a standard number that can be looked up? OD32 NON METAL FLAT RING GASKET, 3.0mm THICK, 150 RF, PTFE, DIMENSIONS PER ASME 16.21. It’s a PTFE gasket; I checked the ASME 16.21 standard and there isn’t an OD32 size for a pressure rating of 150 Is OD32 in MM or inches? DN200 NON METAL FLAT GASKET, 1.5 MM THICK, CNAF, CL150 RF, DIMENSIONS TO ASME B16.21. For non-asbestos gaskets, I checked ASME B16.21 as well – but there is no size for DN200 at a pressure of 150? Thank you all for your advice
