In industrial furnaces, boilers, heat-treatment equipment, petrochemical units, and other high-temperature systems, areas such as furnace doors, flanges, observation ports, expansion joints, and high-temperature pipe connections are often exposed to high temperatures, thermal expansion and contraction, mechanical movement, and frequent opening and closing.

Rigid refractory materials may not always provide sufficient conformity in these locations, which can result in incomplete sealing, localized heat loss, gas leakage, and more difficult maintenance.

For these applications, a flexible, compressible, and resilient high-temperature sealing material is often a more suitable solution.

CCEWOOL® Ceramic Fiber Rope is manufactured from woven ceramic fiber yarn and developed for flexible sealing and insulation in high-temperature equipment.

It combines:

High-Temperature Resistance · Low Thermal Conductivity · Flexibility · Compression Recovery · Structural Adaptability

making it suitable for sealing, insulation, gap filling, thermal compensation, and other high-temperature applications.

Woven Ceramic Fiber Structure

Flexible Sealing for Complex High-Temperature Areas

CCEWOOL® Ceramic Fiber Rope is woven from high-quality ceramic fiber yarn manufactured by CCEWOOL®.

Ceramic fiber provides excellent high-temperature resistance and thermal insulation performance, while the woven construction gives the rope greater flexibility and structural integrity.

Unlike rigid insulation materials such as ceramic fiber board or refractory brick, ceramic fiber rope can be:

Bent · Wrapped · Inserted · Filled · Compressed

This allows it to adapt more easily to furnace door edges, flange connections, pipe surfaces, observation ports, sealing grooves, and irregular equipment joints.

The flexible woven structure also helps create a more continuous seal around equipment connections, reducing localized heat loss and helping limit gas leakage.

Compressible & Resilient

Better Adaptation to Thermal Expansion and Movement

High-temperature equipment repeatedly undergoes heating and cooling cycles during operation.

As temperatures change, equipment structures may experience:

Thermal Expansion · Contraction · Vibration · Slight Mechanical Movement

If a sealing material does not provide sufficient flexibility and recovery, gaps may gradually develop and sealing performance may decrease over time.

CCEWOOL® Ceramic Fiber Rope offers excellent compressibility and recovery, allowing it to maintain closer contact during:

• Furnace door opening and closing
• Flange compression
• Expansion joint movement
• Pipe thermal cycling
• Repeated equipment maintenance

This makes it particularly suitable for dynamic high-temperature sealing locations where long-term flexibility and sealing continuity are important.

Multiple Rope Configurations

Designed for Different Sealing Structures

Different equipment structures require different rope shapes.

CCEWOOL® Ceramic Fiber Rope is available in Round Rope, Square Rope, and Twisted Rope, allowing customers to select a configuration according to the sealing groove, equipment structure, and installation method.

Round Rope

Suitable for:

Flange Connections · High-Temperature Pipes · Valves · Circular Sealing Grooves · Equipment Joints

Its round structure makes it convenient for wrapping, inserting, and localized sealing.

Square Rope

Suitable for:

Furnace Doors · Furnace Frames · Observation Ports · Rectangular Sealing Grooves

The square cross-section provides a larger contact surface, making it particularly suitable for compressed sealing and flat-surface contact.

Twisted Rope

Suitable for:

Gap Filling · Localized Insulation · Temporary Maintenance · Auxiliary Sealing

Its flexible structure makes it especially useful for irregular spaces and applications requiring adaptable filling.

By selecting the appropriate rope configuration, customers can achieve better compatibility with different sealing areas and reduce installation problems caused by mismatched shapes.

Reinforcement Options

Improved Strength and Structural Stability

To meet different requirements for temperature, strength, and durability, CCEWOOL® Ceramic Fiber Rope is available with two reinforcement options:

Fiberglass Reinforced

Fiberglass-reinforced ceramic fiber rope provides good flexibility and is suitable for general industrial high-temperature sealing applications.

Typical applications include:

Industrial Furnaces · Boilers · Flange Connections · Equipment Joints · General Insulation Maintenance

This type is particularly suitable for applications where flexibility, installation convenience, and cost efficiency are important.

Stainless Steel Wire Reinforced

Stainless steel wire-reinforced ceramic fiber rope provides higher tensile strength and improved structural stability.

It is more suitable for applications involving:

Higher Temperatures · Mechanical Vibration · Frequent Opening and Closing · Higher Durability Requirements

Typical applications include furnace door sealing, high-temperature pipe connections, coke oven observation ports, and heavy-duty flange sealing areas.

These reinforcement options allow customers to select a more suitable rope according to actual operating temperature, vibration intensity, opening frequency, and maintenance cycle.

Custom Sizes Available

Better Fit for Different Equipment Structures

In actual industrial projects, sealing groove dimensions, furnace door gaps, flange structures, pipe diameters, and expansion joint widths are rarely identical.

An unsuitable rope diameter, shape, or reinforcement structure may result in:

Insufficient Sealing · Difficult Installation · Improper Compression · Additional On-Site Adjustment

CCEWOOL® Ceramic Fiber Rope supports customization of:

Rope Diameter · Length · Rope Structure · Reinforcement Type

allowing the product to be configured according to actual equipment structures and installation requirements.

Selecting the appropriate specification can help reduce on-site cutting, splicing, and repeated adjustment while improving installation efficiency and sealing continuity.

Wide Applications

From Furnace Doors to High-Temperature Pipe Connections

CCEWOOL® Ceramic Fiber Rope can be widely used in:

Industrial Furnace Door Sealing
Heat-Treatment Furnace Sealing
Coke Oven Door & Observation Port Sealing
Glass Furnace & Ceramic Kiln Sealing
Boiler Door, Flue & Air Duct Connections
High-Temperature Pipe, Valve & Flange Sealing
Expansion Joint Filling & Thermal Compensation
Petrochemical Equipment Connection Sealing
Power Generation & Metallurgical Equipment Maintenance

These applications often share similar requirements: complex structures, close sealing contact, thermal movement, and frequent maintenance.

With its flexible woven structure, compression recovery performance, multiple rope configurations, and reinforcement options, CCEWOOL® Ceramic Fiber Rope provides a more adaptable solution for high-temperature dynamic sealing applications.

CCEWOOL® Ceramic Fiber Rope

Reliable Flexible Sealing for High-Temperature Equipment

High-temperature sealing is not simply about filling a gap.

A reliable sealing solution must consider:

Temperature Resistance · Compression Recovery · Structural Adaptability · Mechanical Strength · Maintenance Convenience

CCEWOOL® Ceramic Fiber Rope combines a woven ceramic fiber structure with multiple rope configurations and reinforcement options, helping customers select a more suitable sealing product for different high-temperature equipment areas.

Whether used around furnace doors, flange connections, observation ports, expansion joints, or high-temperature piping, CCEWOOL® Ceramic Fiber Rope helps improve sealing continuity, reduce localized heat loss, enhance operating stability, and simplify ongoing maintenance.
