Overview
The D-Type Metal Wound Gasket is a high-integrity sealing solution engineered for critical service in industrial piping and pressure vessel systems. It is designed to create a reliable, leak-free seal in high-pressure and high-temperature environments, ensuring operational safety and process integrity. This specific configuration, featuring both inner and outer containment rings, provides exceptional stability and resistance to mechanical and thermal stress, making it a preferred choice for demanding flange connections.
Key Features
D-type construction with integral inner and outer containment rings for maximum gasket stability and blow-out protection. Wound spiral design using 304 stainless steel for excellent mechanical strength and corrosion resistance. Graphite filler material offers superior sealing performance, thermal conductivity, and resilience across a wide temperature range. Engineered specifically for high-pressure applications, suitable for systems operating at substantial pressure levels. Manufactured in compliance with recognized industry standards for dimensional consistency and material quality. Suitable for use in both indoor and outdoor installations without degradation of sealing properties.
