Pressure-Resistant 304 SS Inner Ring Non-Asbestos spiral wound gasket
The 304 Inner Ring Spiral Wound Gasket is a type of sealing material widely used in industrial applications. It is composed of a V-shaped or W-shaped 304 stainless steel strip spirally wound with a non-metallic filler material such as graphite, PTFE, or asbestos-free material. The inner ring, made of 304 stainless steel, provides additional support and helps maintain the gasket's shape and position during installation and operation.
304 Inner Ring Spiral Wound Gasket: Detailed Introduction
The 304 inner ring spiral wound gasket is a high-performance sealing solution designed for demanding industrial applications. Constructed with a 304 stainless steel inner ring and a spiral-wound combination of stainless steel and flexible graphite filler, it offers exceptional strength and corrosion resistance. The inner ring provides structural support, preventing gasket blowout and ensuring proper alignment under high pressure and temperature conditions (up to 800°C/1,472°F in non-oxidizing environments).
Its spiral design adapts to flange irregularities, creating a tight, leak-proof seal. Ideal for pipelines, boilers, and chemical processing equipment, it withstands harsh chemicals, thermal cycling, and vibration. The gasket’s durability reduces maintenance costs while enhancing system reliability. Lightweight yet robust, it combines cost-efficiency with long-term performance, making it a trusted choice in power generation, oil/gas, and water treatment industries.
