Guangzhou Huite Sealing Machinery Co., Ltd.
Flexible Graphite Spiral Wound Gaskets China Suppliers and Factory
High-performance flexible graphite spiral wound gaskets from a leading China factory. Ideal suppliers for flange joints, boilers, and heat exchangers in high-temperature steam and LNG applications.
Product Overview
The Flexible Graphite Spiral Wound Gasket with a Carbon Steel (CS) Outer Ring is a high-performance sealing solution engineered for critical industrial applications. Combining the exceptional resilience of spiral-wound technology with the superior chemical resistance and thermal stability of flexible graphite, this gasket ensures a leak-proof seal under extreme pressure and temperature fluctuations.
Designed specifically for the demanding environments of rubber and plastic processing and general chemical manufacturing, the integration of a robust Carbon Steel outer ring provides essential centering and prevents over-compression. This ensures maximum structural integrity and long-term reliability in flange connections across various industrial piping systems.

Frequently Asked Questions
Q: What is the primary benefit of using flexible graphite in spiral wound gaskets?
Flexible graphite provides superior chemical resistance and can withstand higher temperatures than PTFE or rubber, while offering excellent compressibility for a tighter seal.
Q: Why is a Carbon Steel (CS) outer ring necessary?
The CS outer ring prevents the winding from buckling under high bolt loads and ensures the gasket is perfectly centered during installation.
Q: Are these gaskets suitable for rubber manufacturing plants?
Yes, they are ideal for the high-pressure steam and chemical lines commonly found in rubber and plastics processing facilities.
Q: Can the inner ring be customized?
Yes, while the outer ring is Carbon Steel, we can provide various inner ring materials such as 304 or 316L stainless steel to suit your specific corrosion needs.
Q: How do I choose the correct size for my flange?
We recommend referring to ASME B16.20 or DIN standards. Our technical team can also assist if you provide the flange diameter and pressure rating.
Q: What is the difference between this and a Non-Asbestos Gasket?
Spiral Wound Gaskets with graphite offer higher pressure and temperature recovery compared to flat non-asbestos sheets, making them better for critical joints.
