English description of gasket
Thread Content
I would be very grateful if an expert could help me understand the meaning of the English descriptions for these two types of gaskets: “Flat Gasket, Type RF, CL150, RFG, HG/T 20627, 1.5 mm” and “Gasket, SWG, IR & OR Type, CL150, 304/FG, OR: CS, IR: 304, SH/T 3407, 4.5 mm”. Thank you very much! ! !
“Flat Gasket, Type RF, CL150, RFG, HG/T 20627, 1.5 mm” – A flat gasket used with flanges that have raised sealing surfaces. The pressure rating is CL150, the standard is HG/T 20627, and the thickness is 1.5 mm. It’s similar to “Gasket,SWG,IR & OR Type,CL150,304/FG,OR:CS,IR:304,,SH/T 3407,4.5 mm”; where 304/FG refers to 304 stainless steel strip combined with a graphite filler strip. That is, the winding gasket. IR & OR have inner and outer rings. The outer ring is made of carbon steel, while the inner ring is made of 304 material; the standard is SH/T 3407, and the thickness is 4.5 mm
It was clearly explained upstairs; SWG is the abbreviation for spiral wound gasket.
I don’t know what this means anymore. . Is G a gasket?:(
Could it be Reinforced?
RFG Reinforced Flexible Graphite reinforced flexible graphite gasket
