Full Description

Application context, construction notes, and selection details for evaluating fit before purchase or repeat ordering.

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 for use with standard ANSI flanges, providing a robust sealing solution for systems handling steam, oil, gas, and various chemical process fluids. The gasket's layered design combines the strength of metal with the compressibility of a soft filler, ensuring an effective seal under varying pressures and temperatures.

Key Features

Constructed with 304 stainless steel windings for excellent corrosion resistance Graphite filler material provides reliable sealing across a wide thermal range Integrated inner control ring centers the gasket and provides added blow-out resistance Conforms to established HG industry standards for dimensional consistency Suitable for a broad spectrum of pressure classes within a single gasket design Ideal for indoor use on standard flange connections in controlled environments

Frequently Asked Questions

What are the key specifications and pressure ratings for this spiral wound gasket?
This gasket is manufactured to the HG/T20610-2009 standard with a 4.57-inch inner diameter and is 1/8-inch thick. It is rated for multiple pressure classes: PN16 (232 PSI), PN25 (363 PSI), PN40 (580 PSI), PN63 (914 PSI), PN100 (1450 PSI), and PN160 (2321 PSI), making it suitable for a wide range of flange pressures.
What are the typical applications and use cases for this 304 stainless steel and graphite gasket?
This gasket is designed for sealing flanges in high-temperature and high-pressure piping systems, commonly found in industrial processing, chemical, and petrochemical applications. The 304 stainless steel winding with graphite filler provides excellent resistance to heat (up to approximately 900°F in non-oxidizing atmospheres) and is intended for indoor use on systems carrying oils, gases, and many chemicals.
How is this product packaged, and what is the minimum order quantity?
This gasket is sold in a convenient pack size of 12 pieces. Each gasket is individually packaged or bundled together to prevent damage during shipping and storage, ensuring you receive the quantity needed for standard maintenance or installation jobs.
