Guangzhou Huite Sealing Machinery Co., Ltd.
Flexible Graphite Spiral Wound Gasket CS Outer Ring China Factory Suppliers
High-performance Flexible Graphite Spiral Wound Gaskets from a leading China factory. Ideal suppliers for flange joints, heat exchangers, and pressure vessels, specifically designed for high-temperature steam and low-temperature LNG applications.
The Flexible Graphite Spiral Wound Gasket with a Carbon Steel (CS) Outer Ring is a high-performance sealing solution engineered for critical industrial applications. By combining the exceptional thermal stability of flexible graphite with the structural reinforcement of a precision-engineered spiral wound design, this gasket ensures leak-proof performance under extreme pressure and temperature fluctuations.
Designed specifically for the most demanding environments in the rubber and plastics manufacturing sector, as well as chemical and petrochemical processing, the integrated CS outer ring provides essential centering and prevents over-compression, significantly extending the service life of the seal and reducing maintenance downtime.

Frequently Asked Questions
Q: What are the primary applications of Flexible Graphite Spiral Wound Gaskets?
They are widely used in rubber parts manufacturing, petrochemical plants, and refineries for high-pressure steam, oil, and gas pipelines where thermal cycling is common.
Q: Why is a Carbon Steel (CS) outer ring necessary?
The CS outer ring acts as a centering device and prevents the gasket from being crushed or "blow-out" under excessive bolt torque, ensuring a balanced seal.
Q: How does flexible graphite compare to PTFE in high-temperature environments?
Flexible graphite generally offers significantly higher temperature resistance than PTFE, making it the preferred choice for high-heat industrial steam applications.
Q: Are these gaskets compatible with ASME B16.20 standards?
Yes, our gaskets are manufactured in strict accordance with ASME B16.20 and other international standards to ensure global interchangeability.
Q: Can these gaskets be reused after being disassembled?
For maximum safety and leak prevention, we strongly recommend replacing spiral wound gaskets with every flange disassembly.
Q: What chemical resistance can I expect from flexible graphite?
Flexible graphite is chemically inert to most acids, alkalis, and organic solvents, making it ideal for aggressive rubber and plastic production environments.
