Liluan rock wool pipe is a high-density thermal solution designed for industrial and building services, ensuring thermal conductivity ≤ 0.034 W/(m·K).


Thermal Shielding for Extreme Conditions
Liluan’s rock wool thermal insulation pipe is purpose-engineered for industrial pipelines operating under extreme, sustained high-heat conditions. For process lines carrying superheated steam, hot oil, or high-temperature process fluids, our insulation delivers reliable, long-term thermal performance that outperforms standard fibrous insulation products. Manufactured with high-density basalt fiber cores, these heat-resistant pipe coverings withstand continuous service temperatures up to 600°C without structural degradation, shrinkage, or loss of insulating performance. As reliable pipe insulation material suppliers with decades of industry expertise, we deliver consistent, uniform thermal protection across a full spectrum of heavy industrial applications. Our insulation formulation maintains stable thermal efficiency even under prolonged high-load operating cycles, reducing energy loss and supporting consistent process temperatures.
Fireproof Protection for Industrial Piping
Fabricated entirely from non-combustible natural mineral wool fibers, our industrial pipe insulation rock wool significantly reduces fire hazards for process piping networks. These heat-resistant pipe solutions create a continuous, high-performance protective barrier that effectively slows flame spread and limits heat transfer to adjacent equipment and structures. Industries across oil and gas, power generation, and chemical processing count on Liluan as a trusted pipe insulation material supplier for code-compliant, fire-safe piping systems. All our rock wool insulation materials are rigorously tested to meet major international fire safety standards and building code requirements.
Noise Absorption for Acoustic Efficiency
The dense, interconnected open-cell fiber structure of our rockwool pipework insulation effectively dampens structural pipeline vibration and absorbs airborne ambient noise generated by fluid flow and equipment operation. This dual-function thermal and acoustic solution makes our heat-resistant pipe covering ideal for high-noise environments including manufacturing factories, chemical processing plants, and fossil fuel and renewable power stations. As experienced pipe insulation material suppliers, we work closely with clients to design insulation systems that control occupational sound exposure while delivering reliable thermal performance, helping facilities meet occupational health and safety noise exposure limits. Our products measurably improve on-site acoustic comfort for workers without compromising insulating efficiency or long-term durability.
Durability with Moisture & Corrosion Resistance
Liluan’s rock wool pipe insulation is formulated with advanced hydrophobic additives to resist water absorption, prevent underlying pipe rust formation, and withstand exposure to common industrial chemicals. Unlike fibrous insulation materials that break down in damp environments, these heat-resistant pipe materials maintain dimensional stability and insulating performance in highly humid, chemically corrosive, or exposed outdoor conditions. The inert mineral fiber composition does not promote mold, mildew, or bacterial growth, and resists degradation from UV exposure when installed with appropriate exterior cladding. Additionally, our pipe insulation is compatible with all standard outer jacketing materials, including aluminum, galvanized steel, and PVC cladding, simplifying installation and enhancing long-term durability in harsh environments. Our clients across coastal, tropical, and heavy industrial regions rely on us as pipe insulation material suppliers for long-lasting, low-maintenance insulation solutions. We engineer every product to deliver optimal service lifespan, minimize downtime for replacement or repair, and deliver strong long-term value for industrial facility operators.

FAQ
1. Who are we?
Anhui Liluan Technology Co., Ltd. is an industrial manufacturer specializing in high-performance thermal insulation and acoustic materials since 2009. We operate advanced, automated production lines delivering rock wool, glass wool, and ceramic fiber solutions engineered to meet rigorous international standards for global industrial, commercial construction, and architectural acoustics projects.
2. What are the dimensional specifications and structural advantages of our rock wool pipe sections?
We utilize advanced automated extrusion and molding lines to ensure uniform structural density and strict dimensional tolerances:
-
Density Range: Engineered from 100 kg/m³ to 150 kg/m³ to provide superior compressive strength and structural rigidity under mechanical stress.
-
Precise Concentricity: We match exact internal diameters (ID) to fit standard global piping configurations. This precise fit eliminates longitudinal gaps along the seam line, preventing thermal leakage.
-
Installation Efficiency: Each section features a pre-split, one-piece "snap-on" design. This allows field teams to open, position, and lock the insulation over pipes quickly, lowering on-site labor overhead.
3. What are the maximum thermal limits and primary industrial applications for these pipe sections?
Our high-density rock wool pipes are built for extreme industrial stability and high-temperature performance:
-

-
Core Applications: Primarily specified for heavy industrial processing networks, including high-pressure superheated steam lines, petroleum refinery transport piping, chemical processing plants, and district heating infrastructure.
4. How do our rock wool pipes comply with fire safety standards and mitigate Corrosion Under Insulation (CUI)?
Material purity and safety compliance are critical for global engineering tenders:
-
Fire Performance: Rated as Class A1 Non-Combustible (EN 13501-1) and strictly manufactured to comply with ASTM C547 specifications.
-
CUI Mitigation: Our stone wool formulation features an exceptionally low content of leachable chloride ions. This chemistry minimizes electrochemical reactions on hot steel or stainless steel pipe walls, protecting heavy assets from hidden Corrosion Under Insulation (CUI).
-
