Industrial Un-Faced Mineral Wool Pipe Sections Factory-Direct Supply for High-Temp Lines

Engineered for extreme thermal insulation, acoustic damping, and A1 non-combustible fire protection, our pre-formed un-faced mineral wool pipe sections deliver reliable thermal shielding for high-temperature industrial pipelines and HVAC systems. Manufactured to international standards (ASTM C547 / EN 14303), these rigid, precision-molded pipe shells feature a longitudinal pre-split for quick snap-on installation—eliminating thermal bridging and reducing jobsite labor costs by up to 30%. As a specialized OEM manufacturer and direct exporter, we supply customizable densities and dimensions tailored for MEP contractors, B2B distributors, and industrial procurement teams across Latin America and global markets.

Key Benefits

• A1 Fire Resistance & High-Temp Stability: Withstands continuous operating temperatures up to 650°C (1200°F); completely non-combustible with zero smoke or flame spread.

• Precision Snap-On Installation: Pre-slit cylindrical shells ensure a seamless, tight fit around pipe circumferences, preventing thermal leakage at joints.

• Superior Thermal Efficiency: Low thermal conductivity ($\le 0.034\text{ W/m}\cdot\text{K}$ at 20°C) minimizes energy loss in hot steam, thermal oil, and high-pressure water lines.

• CUI & Moisture Defense: Hydrophobic formulation protects underlying metal pipes against Corrosion Under Insulation (CUI) in humid tropical or coastal industrial environments.

• High Density & Structural Integrity: Rigid molded construction ($80\text{ kg/m}^3$ to $150\text{ kg/m}^3$) maintains uniform wall thickness without sagging over extended operation.

Applications & Industry Scenarios

• High-Temperature Industrial Piping: High-pressure steam lines, thermal oil circuits, power plant piping, and boiler feed systems.

• Heavy Industry & Processing Plants: Oil refineries, chemical processing units, mining facilities, sugar mills, and manufacturing plants.

• Commercial HVAC & Mechanical Rooms: Primary hot water mains and district heating lines intended for field-applied aluminum or cladding jacketing.

Customization & Export Strength

• Tailored Dimensions: Inner diameters from 1/2" to 24"+ and wall thicknesses from 20mm to 100mm+.

• Cladding-Ready Structure: Serves as the high-density insulation core ready for external metal (aluminum/stainless steel) or PVC jacketing.

• Optimized Container Shipping: Custom nested packaging maximizes container volume, drastically reducing sea freight costs per cubic meter to major LATAM ports (Santos, Valparaíso, Callao, Cartagena).

Un-faced mineral wool pipe insulation (plain rock wool pipe sections) serves as the core thermal and fire barrier for industrial fluid transport and heavy-duty mechanical piping. Ideal for projects where field-applied metal cladding is specified, our pre-molded pipe shells deliver long-term thermal conservation, noise reduction, and structural stability.

We support regional insulation distributors, MEP contractors, and industrial procurement teams with flexible production runs and bulk export pricing. With certified quality control (ISO 9001, ASTM), complete Mill Test Certificates (MTC), and fast shipping turnaround, we ensure your high-temperature piping projects stay on schedule and within budget.
