Rockwool 851 (Industrial pipe section)

Product Description

Rockwool 851 is a pre-formed high density stone wool pipe section.

Applications

The sections are supplied split and hinged for easy snap-on assembly and are suitable for the thermal and acoustic insulation of industrial pipe work which is exposed to high temperatures and light mechanical loads (for e.g. vibrations).

Advantages

• Excellent thermal and acoustic insulation
• Easy to handle and install
• Wide range of diameters and insulation thicknesses
• Optimal performance due to the extensive range of diameters
• Suitable for use over stainless steel
• For temperatures up to 350°C, a support construction is not generally necessary
• Long lasting
• Excellent fit provides optimal performance
• Fast return on investment
