Overview

This D-type spiral wound gasket is a premium sealing solution engineered for high-pressure, high-temperature flange connections in critical process industries. It is manufactured to the HG/T20610-2009 standard, ensuring dimensional consistency and performance reliability for nominal pipe size DN65 (approximately 2.5 inches) and pressure class PN25. The gasket's robust, layered construction is specifically designed to create a leak-tight seal in demanding service environments involving aggressive chemicals, thermal cycling, and significant mechanical stress.

Key Features

D-type design incorporates integral inner and outer containment rings. The spiral wound sealing element combines 316L stainless steel and PTFE (polytetrafluoroethylene). Inner ring guides installation and protects the winding from internal media erosion. Outer ring prevents over-compression and gasket blow-out under high pressure. Excellent resilience and recovery properties for long-term sealing performance. Superior chemical resistance provided by the PTFE filler material. Suitable for a wide range of temperatures and aggressive media.

Specifications

Material Grade/Class: 316L Stainless Steel and PTFE Primary Material: Stainless Steel and PTFE Shaft/Bore Diameter: 3.03 inches Thickness: 0.177 inches Pressure Rating: PN25 (Approximately 362.5 PSI) Nominal Size: DN65 Design Standard: HG/T20610-2009 Gasket Type: D-type with Inner and Outer Rings Winding Fill Material: PTFE Winding Metal: 316L Stainless Steel Finish: None (Standard Mill Finish) System of Measurement: Metric (Dimensions provided in Imperial equivalents) Thread Size: Not Applicable

Applications

Sealing flanges in chemical and petrochemical processing systems. High-pressure piping in oil and gas production and refining. Pharmaceutical and food processing equipment requiring chemical inertness. Power generation and utility plant piping. General industrial applications involving steam, acids, solvents, and other challenging media. This gasket is packaged in a convenient quantity of 10 units, providing an efficient inventory solution for maintenance and installation projects.
