Introduction
Braided Graphite Tape is a high-performance sealing material manufactured from flexible graphite yarns that are tightly braided into a continuous tape form. It is engineered to deliver exceptional sealing capability under extreme temperatures, aggressive chemicals, and high-pressure conditions. This advanced tape is widely used in pumps, valves, flanges, and other industrial equipment where conventional sealing materials fail.
Thanks to its self-lubricating nature and superior conformability, Braided Graphite Tape provides a reliable, leak-free seal even on worn or irregular surfaces. It is an ideal alternative to asbestos-based products, offering a safe and environmentally friendly solution for modern industrial sealing applications.
Key Features and Benefits
-
Outstanding Thermal Stability
Braided Graphite Tape withstands continuous operating temperatures from -200°C up to 650°C in oxidizing atmospheres and up to 3000°C in non-oxidizing environments. This makes it suitable for the most demanding high-temperature sealing jobs. -
Excellent Chemical Resistance
The tape is resistant to nearly all organic and inorganic fluids, including acids, alkalis, solvents, oils, and steam. Only strong oxidizing agents such as concentrated nitric or sulfuric acid may affect its performance. -
Low Friction and Self-Lubricating
Graphite’s natural lubricity reduces friction between the tape and the shaft or flange surfaces, lowering wear and energy consumption. This self-lubricating property also minimizes the need for external lubrication. -
High Conformability and Flexibility
The braided structure allows Braided Graphite Tape to conform easily to irregular surfaces, stuffing boxes, and complex geometries, ensuring a tight seal without the need for extensive surface preparation. -
Easy Installation and Removal
The tape can be cut to any desired length and wrapped or wound around shafts, stems, or flanges. It does not harden or bond to metal surfaces, making removal and replacement straightforward. -
Asbestos-Free and Environmentally Safe
Braided Graphite Tape contains no asbestos or hazardous binders, meeting international health and safety regulations.
Applications
Braided Graphite Tape serves a wide range of industries and equipment types, including:
-
Pumps and Valves
Used as gland packing or as a wrap for existing packings to enhance sealing performance in centrifugal pumps, reciprocating pumps, and control valves. -
Flange and Manway Sealing
Ideal for sealing irregular or damaged flange faces, heat exchangers, autoclaves, and manway covers where traditional gaskets cannot provide a reliable seal. -
Boilers and Steam Systems
Suitable for steam valves, boiler handholes, and other high-temperature steam service applications. -
Chemical Processing Equipment
Resistant to aggressive chemicals, making it perfect for reactors, mixers, and pipelines in chemical plants. -
Power Generation
Used in turbines, condensers, and other critical equipment where reliability under high temperature and pressure is essential.

Frequently Asked Questions
Q: Can Braided Graphite Tape be used to replace gland packing rings?
A: Yes, it can be wrapped directly around a shaft or stem as a packing material. For best results, apply slight tension while winding and compress with a gland follower.
Q: Is Braided Graphite Tape suitable for oxygen service?
A: Graphite is generally not recommended for high-concentration oxygen service due to the risk of combustion. Please consult our technical team for specific applications.
Q: How do I store Braided Graphite Tape?
A: Store in a cool, dry place away from direct sunlight. Keep sealed in its original packaging until ready to use to prevent contamination.
Q: Do you provide samples?
A: Yes, we offer free samples for evaluation by qualified B2B customers. Contact us with your requirements.
