1. Who are we?

Anhui Liluan Technology Co., Ltd. is an industrial manufacturer specializing in thermal and acoustic insulation materials since 2009. Our production facility manufactures high-performance rock wool, glass wool, and ceramic fiber solutions, supplying standard and customized insulation variants to the global industrial processing, commercial construction, and HVAC sectors.

2. What are the structural and manufacturing advantages of Liluan glass wool pipe sections?

As a direct manufacturer operating automated production lines, we ensure precise concentricity and uniform density across every section. Unlike standard manual or secondary-processed variants, our pipes feature highly accurate Internal Diameters (ID) ranging from 22 mm to 1220 mm. This precision manufacturing ensures a tight, flush fit onto standard steel, copper, or PVC piping, eliminating longitudinal gaps and preventing localized thermal bridging.

3. What temperature ranges and applications are these pipe sections engineered for?

Our glass wool pipe insulation is rated for operating temperatures up to 440°C (824°F). It is primarily specified for:

• HVAC & Commercial Plumbing: Chilled water lines and hot water distribution systems to prevent ambient condensation and freezing.

• Industrial Processing: Low-to-medium pressure steam lines, district heating networks, and chemical plant process piping to minimize thermal energy loss.

4. What sizing, thickness, and facing options are available for industrial projects?

We provide comprehensive dimensional and material customization to match engineering datasheets:

• Dimensions: Wall thicknesses from 25 mm to 100 mm to meet specified thermal resistance ($R$-values).

• Facings: Available bare or factory-laminated with Reinforced Aluminum Foil (ALU) or Foil-Scrim-Kraft (FSK) to serve as an integrated moisture vapor barrier.

• Design: Each section is produced with a pre-slit longitudinal seam, allowing a rapid "snap-on" installation that minimizes on-site labor time.

5. What services can we provide?

We support international 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: Rigid, moisture-resistant packaging and palletization designed to maximize container space and reduce per-unit ocean freight costs.

• Logistics Dispatch: Streamlined customs clearance and shipping coordination via Nanjing, Wuhu, or Shanghai ports.
