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:

Thermal Threshold: Rated for continuous operating temperatures up to 650°C (1200°F) without structural sagging, binder burnout, or loss of thermal resistance.
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).
Low Shot Content: Advanced spinning technology minimizes non-fibrous particles (shot), ensuring low thermal conductivity and reliable lifecycle efficiency.

5. What services can we provide?

We streamline international B2B procurement workflows with a comprehensive service matrix:

Technical Compliance: Material parameter verification against project engineering specifications (density, thermal conductivity, fire ratings).
Sample Logistics: Provision of standard-sized samples for material testing and physical verification.
Export Packaging Optimization: Heavy-duty, moisture-proof palletized packaging designed to maximize container utilization and protect the black tissue face from abrasion during ocean transit via Shanghai or local river ports.
Logistics Dispatch: Streamlined customs clearance and shipping coordination via Nanjing, Wuhu, or Shanghai ports.
