Corrugated Graphite Tape

At Kriloha Ltd., we recognize that in high-heat maintenance, “Adaptability” is as important as “Integrity.” When you are working on a 12-inch steam valve or a large reactor manway, you need a material that can turn corners without failing. The Kriloha Corrugated Graphite Tape is our engineered answer for “On-Demand” high-temperature sealing. As a premier global provider of industrial seals, Kriloha Gaskets has mastered the Precision Crimping technology required to turn fragile graphite foil into a rugged, flexible sealing ribbon.

The science of Kriloha Corrugated Tape is based on Structural Flexibility. Standard flat graphite tape will “kink” or snap if bent around a tight radius. Our corrugated profile allows the material to expand on the outer edge and compress on the inner edge simultaneously. At Kriloha, we ensure the corrugations are uniform in depth, ensuring that when the flange is tightened, the graphite flows evenly into the flange pits and imperfections, creating a “Molecular Barrier” against leaks.

Manufacturing this tape at Kriloha involves strict Density Calibration. We offer various widths (typically 10mm to 50mm) on convenient spools for easy storage in a technician’s toolkit. Whether you are sealing a high-pressure steam header or an emergency valve leak, Kriloha Corrugated Graphite Tape Gaskets provide the thermal invincibility and mechanical agility your facility demands. By choosing Kriloha Ltd., you are investing in a “Universal Repair Solution” that reduces downtime and eliminates the need to stock hundreds of custom gasket sizes.

Primary Use Cases

Emergency Flange Gaskets: A “universal” gasket-maker for large-diameter flanges, heat exchangers, and vessel covers when pre-cut gaskets are unavailable.
Valve Stem Packing: Can be wrapped and compressed into a stuffing box as a high-performance alternative to braided packing rings in emergency repair situations.
Sight Glass & Level Gauge Seals: Providing a soft, conformable seal for delicate glass components in high-pressure steam service.
Large Diameter Piping: Ideal for sealing large-bore manways and exhaust ducting where traditional spiral-wound gaskets are too expensive or difficult to transport.
Pump & Turbine Split-Cases: Easily follows the complex internal contours of pump housings and turbine horizontal joints.

FAQs

What is the advantage of Corrugated Tape over Flat Graphite Tape?

The corrugations allow the tape to be wrapped into circles or complex shapes without cracking. It also provides a thicker “cushion,” which is better for filling deep pits or irregularities on older flange faces.

How do I install this on a flange?

Simply peel the adhesive backing and apply the tape to the flange face. When you complete the circle, overlap the ends by approximately 10mm to 20mm at a bolt hole to ensure there is no leak path.

Does this tape require a separate sealant?

No. Flexible graphite is a “self-sealing” material. Under bolt pressure, it densifies and flows into the microscopic textures of the metal, creating a bubble-tight seal without the need for messy pastes.

Can I use this for “Emergency” Valve Packing?

Yes. You can wrap the tape around a valve stem and compress it into the stuffing box using the packing gland. The corrugations will crush down into a solid, high-density graphite ring.

Is this material “Fire-Safe”?

Absolutely. Graphite is inherently non-combustible and maintains its sealing integrity during fire events, making it a critical choice for refineries and power plants.
