Spiral Wound Gasket for ASME B16.20 B16.47 Series A Class 150 Flanges, 46 Inch, 304 Stainless Steel With Flexible Graphite Core, High Temperature Variations and Thermal Cycling, 46.50 Inch ID, 52.25 Inch OD, Pipe Size 46, Teadit 900046A304GR150 by Sur
UPC: 00193019753071
✔️ 304 stainless windings with flexible graphite core, Class 150
This spiral wound gasket uses 304 stainless steel windings with a flexible graphite filler, designed for ASME B16.20 gaskets on ASME B16.47 Series A Class 150 flanges. It's ideal for large-diameter piping systems that see heat swings and thermal cycling.
✅ 46.50" ID / 52.25" OD (1181 mm / 1326 mm) sizing for Class 150 flanges
✅ Centering ring locates the gasket precisely on the flange face
✅ Spiral winding combines metal windings with soft graphite filler for sealing
✅ Temperature range -150 to 842 F for high temp service
💡 What is a common use for spiral wound gaskets in piping systems? They seal flange joints in heavy-duty piping with high temps and pressures, especially for ASME B16.20 and B16.47 systems. - Handy for high temp swings and thermal cycling - Improves seating and compression control on large-diameter Class 150 flanges - 304 SS windings with graphite filler resist chemical exposure
