Product Description
Rockwool Plain Pipe Section Insulation for 67mm Pipe Diameter. Rockwool Pipe Sections are strong, non-combustible, pre-formed insulation units for steam and process pipework operating at temperatures up to 700°C. They provide outstanding performance for thermal insulation and sound attenuation. The sections are normally hinged for snap-on assembly and are particularly suitable for the insulation of steel pipework in chemical plants, petrochemical plants and power stations. Process Pipe Sections are available in a number of insulation thicknesses for a wide range of pipe outside diameters.
Advantages
• Excellent thermal and acoustic insulation
• Non-combustible
• Water repellent to BP standard 172
• Chemically inert
• Suitable for high temperature use
• Easy to handle and install
Standards and approvals
Industrial usage
Rockwool Process Pipe Sections are specially manufactured to meet the specification requirements of large industrial users. The non-combustible high density (140 kg/m3), high limiting temperature (700oC) combination provided by the sections ensures that they are ideally suited for use on high pressure steam mains, turbine pipework, boilers pipework, steam heaters, turbine pumps, super heater stations, control valves, etc.
Performance
Fire
Rockwool Process Pipe Sections are non-combustible. Rockwool Fire Duct Section is used to provide fire protection to circular ducts, Fire Tube to pipes and CHS, and H1100 Section to HC-rated plant. Guidance should be sought from Rockwool regarding such applications.
Water resistance
Rockwool Process Pipe Sections are highly water repellent. Process Pipe Sections meet the requirement for water repellence to be maintained subsequent to heating at elevated temperatures, specified by BP Engineering Standard172. When used in the open, Rockwool Process Pipe Sections should be protected with a waterproof covering.
Chemical
Rockwool material is chemically inert. An aqueous extract of the Sections is neutral (pH7) or slightly alkaline.
Durability
Rockwool Process Pipe Sections have been proven in service for over 50 years in all types of exposure. They will give effective protection for the lifetime of the pipes that they insulate.
Biological
Rockwool Process Pipe Sections offer no sustenance to vermin and do not encourage the growth of fungi, moulds or bacteria.
Density
The nominal density is not less than 140 kg/m3.
