What Industries Use Carbon Fiber Packing?

Carbon fiber packing is used in oil and gas, chemical and petrochemical processing, power generation, and marine applications. It seals pumps, valves, agitators, and flanges where operating temperatures reach 455 °C in air or 650 °C in steam, and where PTFE-based packings would extrude or degrade.

Frequently Asked Questions

Q: What is carbon fiber packing used for?

Carbon fiber packing seals pumps, valves, agitators, and flanges in high-temperature and high-pressure service. Typical operating limits are 455 °C in air, 650 °C in steam, and up to 200 bar in valve applications, with pH 0–14 chemical resistance. It is specified where PTFE and aramid packings would extrude or degrade under thermal load.

Common media include steam, hot oils, solvents, and mildly acidic or alkaline process fluids.

Q: What materials are available?

Kaxite supplies carbon fiber packing, carbonized fiber packing with graphite, and carbonized fiber packing with PTFE. Each variant can be impregnated with graphite, PTFE dispersion, or silicone to match specific temperature, pressure, and chemical conditions. Custom cross-section sizes and packaging are available from 100 kg.

All variants are braided in square cross-section, with optional diagonal or interlaced braid structure.

Q: What is your typical lead time?

Standard lead time for bulk carbon fiber packing orders is 10–20 days after order confirmation. In-stock specifications can ship same-day. For urgent shutdown or maintenance windows, expedited production can be arranged with prior notice.

Shipping terms are FOB Ningbo, CIF, or EXW depending on buyer preference.

Q: Do you provide material test reports?

Yes. Every shipment includes a material test report (MTR) and EN 10204 3.1 certificate covering fiber composition, density, tensile strength, and impregnation content. Full batch-level traceability is maintained from incoming raw fiber to finished packing.

Certification documents are issued per batch, not per company.

How do carbon fiber packings work in sealing applications?
Carbon fiber packings work in sealing applications by forming a durable, low-friction barrier that resists compression, heat, and chemical wear. Their braided or woven structure conforms to mating surfaces under gland pressure, creating a tight seal while limiting leakage and extending service life in pumps, valves, and other dynamic equipment.
