Overview
This D-Type spiral wound gasket is a high-performance sealing solution designed for critical flange connections in demanding industrial environments. It is engineered to create a reliable, leak-tight seal in high-pressure and high-temperature piping systems, pressure vessels, and heat exchangers. The gasket's construction combines the resilience of a metal winding with the conformability of a graphite filler, making it suitable for a wide range of media and operating conditions. Its specific design includes both inner and outer steel rings, which provide enhanced structural stability, prevent winding collapse, and facilitate easier handling and installation on large-diameter flanges.
Key Features
D-Type configuration with inner and outer steel reinforcing rings Robust spiral wound construction of steel and graphite filler Engineered for high-pressure service up to 2320 PSI Suitable for elevated temperature applications Provides excellent sealing under variable thermal cycling Reinforcing rings improve gasket handling and positioning Designed for use with raised face flanges
