Overview
The D-Ring Spiral Wound Gasket is engineered for creating a high-integrity, pressure-tight seal in industrial flanged connections. Its robust construction combines a resilient graphite filler with durable 304 stainless steel windings, all contained within concentric 304 stainless steel inner and outer rings. This design provides a reliable seal capable of withstanding significant thermal cycling, pressure fluctuations, and mechanical stress, making it a critical component for maintaining system integrity in demanding process environments.
Key Features
D-Ring design with integral inner and outer centering rings for precise alignment and gasket retention. Spiral wound construction with alternating layers of 304 stainless steel and flexible graphite filler. Excellent resilience and recovery to maintain seal under variable loads and temperature cycles. Superior creep relaxation resistance for long-term sealing performance without frequent retorquing. High-temperature stability suitable for continuous service in oxidizing atmospheres. Conforms to international standard GB/T4622.2-2003 for dimensional consistency and performance.
