Overview
This D-type spiral wound gasket is engineered for critical sealing applications in high-pressure and high-temperature piping systems. Designed to meet rigorous industry standards, it provides a reliable, leak-tight seal for ANSI Class 900 flanges. The construction combines the strength of metal with the conformability of a non-metallic filler, making it an ideal solution for handling demanding process conditions, including thermal cycling and corrosive media.
Key Features
D-type design with integral inner and outer stainless steel rings for controlled compression and bolt load distribution. Spiral wound construction with a 316L stainless steel windings and a flexible PTFE (polytetrafluoroethylene) filler. Engineered for severe service, sealing effectively against corrosive fluids, gases, and steam. Provides excellent resilience to withstand system pressure fluctuations and temperature changes. Manufactured in compliance with recognized industry standards for material and dimensional consistency.
Specifications
Material: 316L Stainless Steel (inner ring, outer ring, and windings) with PTTE Filler Nominal Pipe Size: 1.5 inches Pressure Class: 900 lbs Connection Type: Flanged, for ANSI raised face flanges Gasket Type: Spiral Wound, Style D with Inner and Outer Rings Standards: Manufactured to meet relevant industry specifications for material and dimensions Package Quantity: 12 gaskets
Applications
Primary sealing component for pumps, valves, compressors, and heat exchangers. High-pressure process piping in chemical and petrochemical processing plants. Power generation systems, including steam and utility lines. Oil and gas production, transmission, and refining infrastructure. Any industrial application requiring a robust, standards-compliant seal for ANSI Class 900 flanged connections.
