Explore our premium structural elements, fast-curing prepregs, and precision engineered composite plates.
In industrial thermal management, traditional materials like glass wool, rockwool, and polyurethane frequently fall short under extreme environmental conditions. Structural decay, water absorption, corrosion under insulation (CUI), and susceptibility to chemical damage significantly limit their reliability. Modern high-temperature and structural insulation configurations demand advanced solutions that combine structural integrity with low thermal conductivity.
Carbon fiber pipe insulation and specialized carbon crystal composite protective systems represent the pinnacle of modern material sciences. Using high-purity polyacrylonitrile (PAN)-based carbon filaments (T300 and T700 tiers), these products provide structural backing, chemical inertness, and protection against extreme temperatures. The low coefficient of thermal expansion (CTE) ensures the insulation maintains close contact with underlying pipe systems without cracking or deforming over long operational periods.
Guangzhou RAXis Fiber Co., Ltd. leads this sector by engineering advanced carbon fiber jackets, tubes, and thermal barrier substrates. Our composite components are designed to withstand structural loads while integrating custom thermal core layers. This layout delivers double-action insulation and physical protection for pipelines in aerospace, chemical refineries, LNG transportation, and high-tech manufacturing plants globally.
Comparing high-performance composite solutions to standard materials reveals significant long-term performance benefits.
Traditional metal cladding allows moisture retention, leading to rapid pipe wall degradation. Carbon fiber jackets are completely rust-proof, hydrophobic, and chemically inert, stopping CUI and saving on maintenance costs.
With high tensile strength (up to 4900 MPa for T700 grades) and low density (~1.8g/cm³), our carbon fiber pipeline sleeves provide structural protection without adding structural load to long-span overhead pipe racks.
Engineered to withstand temperatures from cryogenic levels up to 300°C with epoxy matrices, and over 1000°C using carbon-carbon (C/C) matrix compositions, ensuring thermal insulation and structural stability.

| Performance Metrics | Carbon Fiber Composite Sleeving | Fiberglass (GRP) Jacketing | Aluminum / Metal Cladding | Polyurethane / Rockwool Jackets |
|---|---|---|---|---|
| Tensile Strength (MPa) | 1500 - 3500 (Extreme Structural) | 200 - 450 (Moderate) | 70 - 250 (Prone to denting) | Minimal (Relies on outer cladding) |
| Density / Weight (g/cm³) | 1.5 - 1.8 (Ultra-Lightweight) | 2.2 - 2.5 (Medium Weight) | 2.7 - 7.8 (Heavyweight) | 0.05 - 0.2 (Light, lacks structural integrity) |
| Corrosion Resistance | Outstanding (Acids, Alkalis, Saline) | Good (Prone to osmotic blistering) | Poor (High risk of galvanic/acid rust) | Extremely Poor (Absorbs moisture, leads to CUI) |
| Thermal Expansion (CTE) | Near Zero (-0.5 to 1.5 ppm/K) | 7 - 12 ppm/K | 23 ppm/K (High expansion cracking) | N/A (Breaks down under expansion stress) |
| Service Lifespan (Marine/Industrial) | 30+ Years (Zero Maintenance) | 10 - 15 Years | 5 - 10 Years (Requires frequent inspection) | 2 - 5 Years (Demands regular replacement) |
