Chapter 1
What is Rockwool Pipe?
Your go-to insulation for industrial piping systems
Rockwool Pipe is a high-performance thermal insulation solution crafted from mineral rock wool fibers, engineered to reduce heat transfer in piping systems. Ideal for industrial, commercial, and petrochemical applications, it provides superior temperature resistance (up to 650℃) and low thermal conductivity—making it a top choice for energy-efficient insulation worldwide. The thermal insulation rock wool pipe is single-sidedly split along the axis of the shell, which is convenient for construction and can ensure that the shell and the pipe that needs insulation fit closely. The outer surface of the shell can be polished according to customer requirements to ensure the precise consistency of the insulation thickness. Hydrophobic and low-chlorine products can also be produced according to customer requirements, or aluminum foil, glass fiber, and other materials can be attached to the surface.

Quality Assurance for Rockwool Pipe
Henan Jianhong Refractory strictly adheres to ISO 9001 quality standards, utilizing advanced testing equipment for comprehensive inspections. Every batch of our Rockwool Pipe undergoes rigorous testing, ensuring it meets global quality benchmarks and your exacting requirements for reliability, durability, and performance.
The key quality tests typically include:
| Inspection Category | Inspection Item | Inspection Content | Inspection Method |
|---|---|---|---|
| Basic Appearance | Surface Quality | Check for cracks, holes, obvious stains, agglomeration, or exposed fibers; ensure the surface is flat. | Visual inspection (under natural light or standard light source). |
| Edge & Corner Condition | Check for edge breakage, corner damage, or irregular cutting; ensure edges are neat. | Visual inspection and ruler measurement. | |
| Dimensional Accuracy | Length/Width | Measure actual length and width, check if they meet the specified tolerance range (usually ±5mm for common specifications). | Use a steel tape measure (accuracy ≥1mm) to measure at 3 different positions and take the average. |
| Thickness | Measure thickness at multiple points (≥5 points evenly distributed), check if it meets the tolerance requirement (usually ±5% of the nominal thickness). | Use a thickness gauge (with a pressure of 2kPa±0.5kPa). | |
| Physical Performance | Bulk Density (Density) | Measure the mass per unit volume, check if it is within the specified range (e.g., 48-120 kg/m³ for common products). | Cut a sample of regular shape, weigh it with a balance (accuracy ≥0.1g), and calculate volume. |
| Thermal Conductivity | Test the heat transfer performance at 25℃ (average temperature), ensure it meets the standard (e.g., ≤0.044 W/(m·K) for products with density ≥80 kg/m³). | Use a heat flow meter or guarded hot plate method. | |
| Compressive Strength | Test the maximum pressure the product can bear without excessive deformation (compression deformation ≤10%), meet the specified value (e.g., ≥40 kPa). | Use a universal testing machine, apply pressure at a speed of 10mm/min. | |
| Tensile Strength (Vertical & Horizontal) | Test the resistance to pulling force, ensure it meets the requirement (e.g., ≥7.5 kPa for vertical tensile strength). | Use a tensile testing device with a constant speed of 50mm/min. | |
| Water Absorption (Volume Ratio) | Test the volume percentage of absorbed water after immersion, meet the standard (e.g., ≤5% for water-repellent products). | Immerse the sample in water for 24h, calculate the volume of absorbed water. | |
| Slag Ball Content | Test the mass percentage of slag balls (diameter >0.25mm), meet the requirement (e.g., ≤10% for high-quality products). | Sieve the sample, weigh the slag balls retained on the sieve. | |
| Combustion Performance | Combustion Grade | Verify the combustion performance grade (e.g., A1 or A2 grade，non-combustible), check for flame spread, smoke production, or dripping. | Use a cone calorimeter or vertical burning test device. |
| Hot Load Shrinkage Temperature | Test the temperature at which the product shrinks by 4% under heat load, meet the standard (e.g., ≥600℃). | Heat the sample at a rate of 5℃/min, monitor shrinkage with a displacement sensor. | |
| Chemical Performance | pH Value | Test the acidity/alkalinity, ensure it is within the range (e.g., 7-9 for neutral products). | Use a pH meter to test the extract solution of the sample. |
| Chloride Ion Content | Test the mass percentage of chloride ions, meet the limit (e.g., ≤0.03%). | Use ion chromatography to analyze the extract solution. | |
| Average Fiber Diameter | Test the average diameter of rock wool fibers, meet the requirement (e.g., ≤7μm). | Use a microscope to measure fiber diameters (≥100 fibers), calculate the average. | |
| Safety & Environmental Protection | Formaldehyde Emission | Test the release amount of formaldehyde, meet the limit (e.g., ≤0.1mg/m³). | Use the environmental test chamber method. |
| Radionuclide Limit | Test the specific activity of radionuclides (Ra-226, Th-232, K-40), meet the A Category Requirements (radioactivity index Iγ≤1.0). | Use a gamma spectrometer to measure the radionuclide content. | |
| Packaging & Labeling | Packaging Integrity | Check if the packaging is intact, moisture-proof, and anti-collision; ensure no damage during transportation. | Visual inspection, check for tears, water stains, or looseness. |
Through this meticulous testing process, we ensure that our Rockwool Pipe products meet the highest standards of quality, reliability, and performance, making them ideal for various applications in various industries.
