Sub Sea Insulation
ROCKWOOL´s unique product properties within fire resistance, water and moisture repellent, sound reduction and thermal conductivity, which traditionally have been used e.g. within the marine and offshore sector, can now with benefit be used for thermal insulation of Sub-Sea Pipelines.
The increased efficiency improvement when drilling for oil and use of the world's oil reserves mean that we operate on deeper ocean depths with increasing temperatures of the crude oil as a consequence. Precisely here, the combination of ROCKWOOL´s capability to resist high temperatures and good insulating qualities appears.
Aquaduct has already been used successfully in Sub-Sea projects world wide for several years. We offer individual and customised solutions to match the specific conditions and needs: Pipe-in-pipe system, Pipe Bundles, Field Joints and Bespoke solution.
Advantages
• Resistant to high temperatures
• Resilient; good recovery following deformation
• Free from HFCs and other glowing gases
• Unaffected by welding of field joints
• Easy to handle and install
• Reliable performance; thermal conductivity cannot degrade due to loss of entrapped gas
• Recyclable
Product Range
Aquaduct Insulation system incorporate a number of different Rockwool products which can be tailor made for the individual project and purpose. Some of the products are described below:
Aquaduct CL are special patented Rockwool products where the vertical direction of the fibres provides an excellent compression resistance at low thicknesses (down to 10 mm thickness). The fibres are bonded to a reinforced aluminium foil outer facing and the product can be supplied with very low tolerances. In most cases Aquaduct CL will be the optimal choice for Pipe in Pipe solutions.
Aquaduct Sections are rigid pre-formed circular units of Rockwool insulation supplied with or without an outer covering. Aquaduct sections are available in almost any combination of diameter, thickness and length and can be adapted to individual needs and specifications. Aquaduct Sections are the optimal choice for bigger sizes of pipe.
Aquaduct PSM is a rigid Rockwool slab having a glass scrim or reinforced aluminium foil facing bonded to one side and triangular grooves in the other. The grooves allow the slab to wrap around and closely fit specified large diameters.
Aquaduct Bevelled Lags are trapezoidal strips of Rockwool rigid slab designed to contour specified large diameters. The lags can be supplied loose or bonded to a reinforced foil or metal outer sheet. The use of Aquaduct Bevelled Lags offers the designer the facility to incorporate inset strips of varying thicknesses.
Aquaduct Loose Fill is a specially graded, granular insulation designed to in-fill around pipe bundles and to fully fill irregular voids. Aquaduct Loose Fill can be installed at a wide range of densities, either by hand packing or by use of specially designed blowing equipment.
