Overview
The D-Shape Metal Wound Gasket is a precision-engineered sealing solution designed for high-pressure, high-temperature flange connections in industrial piping systems. Its robust, spiral-wound construction creates a reliable, leak-tight seal that accommodates thermal expansion and flange rotation, making it ideal for demanding process environments. This gasket is manufactured to conform with recognized industry dimensional and material standards, ensuring consistent performance and interchangeability in critical applications.
Key Features
D-shaped design with inner and outer retaining rings for precise alignment and installation stability. Spiral-wound construction combining alternating layers of metal and flexible graphite filler. The metal winding provides mechanical strength and resilience under load. The graphite filler offers excellent sealing, thermal conductivity, and chemical resistance. Engineered for service in systems with high thermal cycling and pressure fluctuations. Retaining rings prevent over-compression and protect the wound seal from handling damage. Suitable for a wide range of industrial media, including steam, hydrocarbons, and various chemicals.
Specifications
Material: Steel winding strips with a graphite filler, 304 stainless steel inner and outer rings. Nominal Size: 12.2 inches. Pressure Rating: Suitable for PN16 flange systems, corresponding to a maximum working pressure of approximately 232 PSI. Standards: Design and dimensions conform to recognized industry standards for spiral wound gaskets. Connection Type: Flange gasket. Package Quantity: 20 pieces per box.
Applications
Primary sealing for pipe flanges, valve bonnets, and pump casings in chemical and petrochemical processing. Sealing for steam lines, heat exchangers, and boiler feed systems in power generation. General high-pressure sealing in oil and gas production, refining, and pipeline infrastructure. Use in industrial heating, cryogenic services, and other applications requiring a resilient, metallic seal.
