Rockwool Pipe Sections

DESCRIPTION

ROCKAL Performed Pipe Section are made of rockwool fibers spun from molten basaltic rocks bonded together by a thermo-setting resin binder.

The fibers are molded around the pipes of different standard diameter at the required thickness and dried to form rigid hollow cylinder insulation, which then is linearly slit to allow easy installation.

Application

• ROCKAL Performed Pipe Section is used over a very wide range of temperatures to insulate all sizes of cold and hot piping. Like domestic water in buildings and chemical process such as in oil refineries, chemical and Petro-chemical insulation and desalination plants, HVAC chilled water systems, oil pipelines.
• ROCKAL Pipe Section used as acoustic insulation of pipelines where gas fluids or solid particles are transferred in high velocities.
• ROCKAL Performed Pipe Section is used as a fireproof insulation for pipes and ducts in high-risk areas

 

Facing

ROCKAL Rockwool Pipe Section comes non-faced or faced with reflective vapor barrier material (Reinforced Aluminum foil FSK).

Advantages

• Fire-resistant: Rockal Rockwool pipe section has a high melting point and is able to withstand high temperatures, making it an excellent choice for fireproof insulation.
• Moisture-resistant: Rockal Rockwool is a hydrophobic material, meaning it is resistant to moisture and will not absorb water, which can lead to mold and other moisture-related problems.
• Energy efficient: Rockal Rockwool provides excellent insulation properties, helping to reduce energy costs and improve the energy efficiency of a building.
• Environmentally friendly: Rockal Rockwool is made from natural, abundant minerals and is produced using renewable energy sources, making it a more environmentally responsible choice than some other types of insulation.
