Guangzhou Huite Sealing Machinery Co., Ltd.
Premium Flexible Graphite Spiral Wound Gasket with CS Ring | China Factory Suppliers
High-performance Flexible Graphite Spiral Wound Gaskets from a leading China factory. Trusted suppliers for flange joints and pressure vessels, designed for high-temperature steam and low-temperature LNG applications.
The Flexible Graphite Spiral Wound Gasket with a Carbon Steel (CS) Outer Ring represents a pinnacle of sealing technology, specifically engineered for high-stakes industrial environments. By integrating the exceptional thermal stability of flexible graphite with a precision-engineered spiral wound architecture, this gasket delivers a robust, leak-proof seal capable of withstanding extreme pressure surges and volatile temperature fluctuations.
Tailored for the rigorous demands of rubber and plastics manufacturing, as well as chemical and petrochemical processing, the integrated CS outer ring provides critical centering and prevents over-compression. This strategic design significantly extends the operational lifespan of the seal, minimizes maintenance downtime, and ensures maximum safety in high-pressure piping systems.

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.
