Stonewool Preformed Pipe Sections
Description
Stonewool preformed pipe sections is a resin bonded Stonewool preformed into rigid, cylindrical sections. Available plain or covered with canvas where painting/colour coding is required, or covered with aluminium foil where a vapor barrier is required. Specially developed additives are used which give the product high resistance to the ingress and absorption of water. This water repellency is an integral feature of the insulation and not simply a surface treatment.
Application
Thermal and acoustic insulation of pipe work in power generation, oil refineries, chemical plants and on industrial steam and process pipe work.
Operating Temperature
Plain preformed pipe sections can be used at continuous operating temperatures of up to 850C. Canvas covered and foil-faced preformed pipe sections - limiting temperature of outer facing is 50°C.
Acoustic Performance
Will provide effective acoustical insulation where there is a need to reduce noise levels from pipe work or to absorb sound in other applications. Actual performance varies with thickness and density.
Fire Performance
- Non-combustible - Tested to SABS 0177 Part V.
- Class I Fire Index - Tested to SABS 0177 Part 111.
Permanence
Rot-proof, odourless, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. Will not settle under vibration and is dimensionally stable under varying conditions of temperature and humidity.
Biosolubility
The IARC (International Agency for Research on Cancer), part of the World Health Organization, has classified Stonewool as a group 3 product - not classifiable as to carcinogenicity to humans. The fibres from Isover Stonewool products are bio-soluble and will dissolve in lung fluid and pass through the body naturally.
Standard Dimensions
- Length: 1000 mm
- Bore size: to insulate steam pipes from 15 mm NB to 700 mm NB
- Thickness: 25 mm to 100 mm (see price list for detailed specification)
- Nominal Density:
- 200 mm NB 185 kg/m³
