Rubber Pipe Insulation Sizes & Configurations
FUNAS rubber pipe insulation is available in multiple inner-diameter and wall-thickness combinations for HVAC, refrigeration and mechanical piping applications.
When selecting a size, match the insulation inner diameter to the actual pipe outside diameter. Not every inner diameter is available in every thickness, so the required combination should be confirmed before ordering.
Custom sizes and colors are also available subject to production confirmation.
Standard Size Range
| Wall Thickness | Standard Inner Diameters | Length |
|---|---|---|
| 9 mm | 6, 10, 13, 16, 19, 25, 32, 43, 51, 60 mm | 1.8 m |
| 13 mm | 6, 10, 13, 16, 19, 25, 34, 43, 48 mm | 2.0 m |
| 15 mm | 6, 10, 13, 16, 19 mm | 2.0 m |
| 20 mm | 6, 10, 13, 16, 19, 22, 25, 28, 34, 43, 48, 60 mm | 2.0 m |
| 25 mm | 25, 28, 34, 43, 48 mm | 2.0 m |
| 30 mm | 22, 25, 28, 34, 43, 48, 60, 76, 89, 108 mm | 2.0 m |
Custom dimensions are subject to production confirmation.
HVAC, Refrigeration & Chilled Water Pipe Insulation
FUNAS closed-cell NBR/PVC elastomeric pipe insulation is suitable for a range of HVAC and mechanical piping applications, including:
• HVAC and air-conditioning piping
• Chilled-water systems
• Refrigerant and refrigeration lines
• Hot and cold mechanical piping
• Equipment and piping connections
-
For cold piping systems, insulation thickness and joint sealing should be selected according to the actual operating temperature, ambient conditions and project requirements.
Selecting Rubber Pipe Insulation for HVAC & Refrigeration
For specification confirmation, provide the pipe outside diameter, required insulation thickness, operating conditions and B1/B2 grade.
The required insulation thickness should be selected according to the actual piping system and project conditions rather than using one standard thickness for every application.
During installation:
• Seal longitudinal and butt joints continuously.
• Cut and fit the insulation carefully around elbows, tees, valves and fittings.
• Maintain insulation continuity at pipe supports.
• Avoid stretching the material during installation.
• Stagger joints when multiple insulation layers are used.
-
For outdoor installations, use a suitable protective facing or weather-resistant covering. Aluminum foil-faced rubber pipe insulation is available as an optional configuration.
