Overview
This industrial-grade spiral wound gasket is engineered for creating reliable, high-integrity seals in demanding piping and pressure vessel applications. It is specifically constructed to handle the challenges of chemical processing, petrochemical, and power generation systems where thermal cycling and high pressure are common. The gasket features a precision-wound design that combines the spring-like resilience of metal with the conformable sealing properties of a non-metallic filler, ensuring a robust metal-to-metal seal at the flange faces.
Key Features
Engineered for a 150 LB pressure class rating, suitable for standard industrial flange connections Constructed with a corrosion-resistant 316L stainless steel winding for enhanced durability in harsh environments Features a flexible graphite filler providing excellent thermal conductivity and sealing across a wide temperature range Incorporates an inner and outer containment ring for improved gasket handling, alignment, and prevention of over-compression Manufactured in compliance with the HG/T20631-2009 standard, ensuring dimensional consistency and performance reliability Designed for a nominal pipe size of 1 inch (DN25)
