Rockwool Preformed Pipe Section

Fujairah Rockwool Preformed Pipe section conforming to ASTM C-547 and equivalent BS 3958-4 is intended for the thermo-acoustic insulation and fire protection of pipe works operating at high temperatures.

The pipe insulation is manufactured from long non-combustible rock fibers with a high performance binder. It is easy to cut, fit, handle and has levels of thermal efficiency and strength. Each section is split and hinged for easy, snap-on applications.

Designed for tough thermal and acoustic insulation pipe works, its combination of density, strength and excellent thermal conductivity at high operating temperatures offer efficient insulation. It is highly applicable for industrial steam and process pipe lines in oil refineries,
chemical plants and power stations. It also has the versatility to be used in heating and ventilating or other non-industrial applications.

Density range from 100-180 kg/m3.
180 kg/m3 density is available up to 8” diameter
Thickness range from 25-120mm. Above 120mm can be in multilayer.

Fujairah Rockwool Preformed Pipe Section shows remarkably low thermal conductivity values.
Typical figures are shown in accordance with ASTM C-335. We have test report at different mean
temperatures for 140 kg/m3 nominal density.

These are typical values subjected to normal manufacturing and testing variance. The table shows the results for their raw density in accordance with the test report.

Preformed Pipe

Rockwool Insulation has a service temperature of 780°C when tested in accordance with DIN 52271 for 80mm thickness and 100 kg/m3 density.  However there is possible deviation for lower densities.

The user is advised that it is possible that the maximum use temperature of facings and adhesives is lower than the maximum use temperature of the insulation. The user shall ensure that sufficient thickness shall be installed so none of these accessory items (facings and adhesives) are exposed to temperatures above their maximum use temperature.

Non-combustible when tested in accordance with BS-476 part 4, ASTM E-136 and BS EN ISO 1182. Class A, when tested in accordance with ASTM E-84. The products have been tested following BS EN ISO 1182 and BS EN ISO 1716 and shown a reaction to fire performance of Class A1 following BS EN 13501-1 and can be considered as non- combustible.

Suitable for acoustical insulation as per BS-3638 and ISO 0354, and ASTM C423

Compatible with all other forms of material with which it is likely to come in contact in normal industrial and building applications.

Water repellent, non-hygroscopic, non-capillary it does not absorb any moisture from the air. Water absorption test certificates conducted under BS 2972 : Section 12 ASTM C-209 are available upon request.

Chemically neutral with a pH value of 7-8 when tested in accordance with BS 2972 : Section 22. It will neither cause nor promote corrosion. It meets the requirements of ASTM C-795 the standard specification for thermal insulation for use in contact with austenitic stainless steel when measured according to standard methods of ASTM C - 692 (Corrosion Test) and ASTM C -871 (Chemical Analysis). It contains low level of chlorides when tested in accordance with BS 2972 : Section 21, ASTM C-871 and AGI Q 135.

 

Asbestos free and shot content is very low when tested as per  ASTM C-1335 and BS 2972: Section 14. 

Rot-proof, non-hygroscopic, will not sustain vermin and will not encourage growth of bacteria, mold or fungi.

Supplied in shrink wrapped polyethylene sheet.
