Premium Industrial Pipe Insulation Shells | Rock Wool, Glass Wool & Aluminum Silicate Solutions

Expert Insights from Ruibin, Lead Technical Consultant at Hebei Woqin

"In industrial thermal protection, the core material must match the thermal stress of the environment," says Ruibin. "At Hebei Woqin, we offer a 'Triple-Core' system, allowing our clients to choose between Rock Wool, Glass Wool, or Aluminum Silicate based on their specific engineering requirements, ensuring zero condensation and maximum energy savings."

I. The "Triple-Core" Material Selection Guide

Instead of a single product, we provide tailored solutions based on your operating temperatures:

Rock Wool Core: The industrial standard for steam and boilers, stable up to 600°C - 650°C.

Glass Wool Core: Optimized for HVAC and building cooling/heating, working up to 450°C.

Aluminum Silicate Core: Specifically for extreme metallurgy and furnaces, withstands up to 1000°C+.

II. Certified Technical Specifications (GB/T 11835-2016)

(Note: Use the following data as your technical benchmark)

Thermal Conductivity (70°C): ≤ 0.044 W/(m·K)

Thermal Conductivity (25°C): ≤ 0.032 W/(m·K)

Max Service Temperature: Reliable performance up to 600°C

Fire Performance: Class A1 (Non-combustible)

Hydrophobic Rate: ≥ 98% (Excellent moisture resistance)

Standard Density: 80 - 150 kg/m³

Corrosion Control: Strictly controlled chloride and fluoride ions per JC/T 618-2019 to prevent pipe corrosion.

Dimensions: Inner Diameter 18-610mm, Thickness 30-200mm, Length 1000mm.

III. Proven Project Success Stories

Dubai Petrochemical Pipeline: Supplied 150mm thick rock wool for 300°C steam pipelines. Surface temperatures reduced to below 50°C, remaining stable even in high-humidity seasons.

Rotterdam Warehouse Roofing: Installed 100mm thick insulation under metal sheeting, achieving a U-value of 0.35 and significantly reducing ambient noise.

Mumbai Food Factory: Used 80 kg/m³ density partitions that remained stable without sagging even in 95% humidity.

IV. Commercial Information & Shipping

2026 Factory Direct Prices: Starting from $3-$10/m² depending on density and thickness (FOB Tianjin Port).

Minimum Order Quantity (MOQ): 1x20GP container (500m² minimum).

Customization: Facing options include Aluminum Foil, Kraft Paper, or White PVC.

Free Sample Service: 1-2 square meter samples are available worldwide for project testing.

Expert Tip by Ruibin:

"Golden Rule: Do not over-compress during installation. A 15% reduction in thickness can degrade thermal performance by 15%. If aerogel is over your budget, our rock wool is the preferred bulk alternative. Please provide your pipe size, and my team will suggest the ideal density within minutes."
