  • WO2004/022503 discloses concrete containing polyurethane is provided and construction elements comprising such concrete. Methods for the preparation of polyurethane for inclusion in such concrete and for the formation of construction elements comprising such concrete are also provided. The strength and insulating properties of the concrete is not disclosed.
  • US 5,422,051 discloses cementitious concrete made from recycled plastics, Portland cement, and sand/gravel fillers performs to standards of concretes made without plastics. Heterogeneous plastic materials may be used in this concrete, removing the previously time and resource intensive step of sorting and melting down constituent plastics from each other in the waste stream. No insulating properties are disclosed.
  • WO96/30315 discloses insulating mortar which displays very good heat-insulating properties. It contains at least 70 vol. %, preferably at least 80 vol. %, in particular at least 85 vol. %, recycled, comminuted hard polyurethane, the remainder consisting of cement and optionally additives as well as water for setting purposes. No strength properties are mentioned.
  • the significance of this invention is the blend of high strength concrete materials such as the materials manufactured by the company Densit ApS of Denmark with various types of insulating materials that demonstrate similar or improved material properties compared to typical concrete blends.
  • the concrete formulation is described as a cement-based material comprising a coherent matrix, the matrix comprising
  • the typical high strength concrete materials such as materials from Densit ApS can be formulated with a number of different additives in order to achieve significant strength improvements over traditional concrete formulations.
  • insulating materials By adding insulating materials to high strength concrete materials such as Densit® ultra high strength concrete materials significant insulating properties can be achieved and still achieve mechanical properties similar to typical concrete formulations, however with significant insulating properties as well as weight and price reductions
  • High strength concrete materials such as Densit® ultra high strength concrete materials are mostly used for applications related to floor, pavement as well as offshore applications where extreme strength and mechanical properties out perform the usual use of concrete formulations. Due to these properties materials such as Densit® ultra high strength concrete materials have gained a significant marketplace with-in its typical applications.
  • the material according to the invention opens a whole new range of products and applications where the material blended with different insulating materials can be applied to present concrete applications without significant changes of the present concrete properties and added insulation properties.
  • the material according to the invention has several application platforms where significant achievements can be reached. The achievements are all related to the combination of insulation performance along with structural and physical strength of the material. The following platforms are:
  • the basis of all the applications are the formulation of high strength concrete such as the materials provided by the company Densit ApS of Denmark and blended with the insulating materia!.
  • the significance of insulating material is the size and insulation capability when the materials are imbedded into the high strength concrete material. The more of the insulating material, the less weight and the more the overall insulation capability of the total matrix can be achieved, as well as a reduction of the physical properties, especially the strength, however still comparable with concrete formulations.
  • Another important feature is the possibility to adjust the density of the high strength concrete with insulating material to exactly to the needed in relation to the other desired properties
  • Concrete matrices with added insulating materials are not typical seen applicable in the market due to lack of comparable performance related to other insulation concepts, like foamed polyurethane (PUR) for district heating pipes, mineral wool for building applications and industrial insulation concepts.
  • PUR foamed polyurethane
  • the major advantage of the present invention is the fact that two different types of bonding, determined by the nature of the insulating material, is clearly seen effective between the added insulating materials and the high strength concrete materials such as the Densit® ultra high strength concrete materials.
  • insulating materials comparable to concrete and high strength concrete materials such as Densit® ultra high strength concrete materials will have the ability to interface on a molecular basic and therefore the insulating material it self makes a contribution to the achievable strength that thereby forms a strong matrix that outperforms typical concrete blends and further have substantial improved insulation properties.
  • Typical materials could be glass-spheres, Leca®, nano-tubes and other inorganic materials
  • the significance of the bonding of the other "type" of insulating materials, based on polymeric materials, are more related to the in capsulation of the insulating particle into the high strength concrete material such as the Densit® ultra high strength concrete materials, where the insulating material itself does not make a contribution of strength, however being blended with the right particle size and volume the high strength concrete materials such as Densit® ultra high strength concrete materials can be engineered and tailored to the specific application mentioned earlier.
  • Typical polymeric materials could be EPS, PUR, foamed PP or other foamed insulating material.
  • Another significant advantage is the fact that even if highly combustible insulating materials, are embedded into the high strength concrete material such as the Densit® ultra high strength concrete materials, the blend performs with the highest fire ratings possible, due to the encapsulation of the non-flammable or flammable insulating material into the non-flammable high strength concrete material such as the Densit® ultra high strength concrete materials.
  • This allows the composition according to the invention to be applied or sprayed onto surfaces that needs to retain an inflammable and at the same time, due to its insulating properties, delays melting of possibly metallic structural elements to which the composition according to the invention is applied and thereby the metal structural elements can retrieve its physical properties for a longer period of time.
  • a major advantage is also present for the composition according to the invention, when applied to sub-sea-level pipelines. Insulation of pipelines can be provided for one or more different reasons:
  • Insulation of offshore pipelines in order to ensure a certain flow rate 2) Insulation of onshore pipelines in order to ensure terrorism protection 3) Insulation of pipelines in general, e.g. for ensuring a certain temperature.
  • offshore pipelines The significance of offshore pipelines is the nature of the fluid that is to flow inside the pipeline. Waxing and other fluid components need to remain above a certain temperature throughout the length of the pipeline to prevent clocking of the pipeline.
  • the essential parameters for offshore pipelines are governed by the needed insulation in order to assure that the fluid being carried, maintains its properties until further processing is feasible. At the same time the size of the pipe diameter and the water depth determines the weight of the coating necessary in order to maintain the necessary buoyancy and weight that will keep the pipeline in position on the bottom of the sea.
  • Three insulation concepts are typical used for the present offshore pipelines:
  • the principle of the laying method applies to deep sea pipelines laid on water depths deeper than typical 500-1500 meters with a laying speed of 1 to 3 km/day
  • the principle of the laying method applies typical to pipelines laid down to 0-1500 meter with a laying speed between 5 and 7 km/day depending on which of the 3 insulation concepts being used
  • the principle of the laying method applies to pipelines laid on all water depths, however not all types of insulation concepts are that well suited for this method, as the strength of the insulation determines the suitability
  • the principle of the laying method is applied after the pipeline have been welded and joined on shore, the pipeline is towed to the site and lowered to its potion on the sea.
  • Single pipes are described as pre-insulated pipes for district heating, comprising of a medium conveying pipe, an insulating material surrounding at least a part of the length of the medium conveying pipe and a jacket pipe at least partly surrounding the insulating material.
  • the single pipe may be provided with an insulating material surrounding at least a part of the length of the medium conveying pipe, but without a jacket pipe surrounding the insulating material.
  • Such pre-insulated pipes are mostly used for any media at a temperature between -200 0 C and +315°C in order to provide insulation of different media when applied on-shore.
  • the media temperature is usually restricted to an application temperature between -48°C and +160 0 C depending on the water depth and the required insulation thickness .
  • an object of the present invention may also be to provide a pre- insulated pipe of the kind mentioned above, simplified by having sufficient insulation properties and at the same time having the sufficient weight to perform as a weight coating.
  • a one layer solution not only provides an impermeable insulation coating it also provides simplified joint solutions as well as insulation properties independent of the water depth as the impact from the outer pressure is related to the high strength concrete material such as Densit® ultra high strength concrete materials and not the polymeric matrix usually being the designing parameter for pre-insulated pipes according to the described single pipe system.
  • the high strength concrete material such as Densit® ultra high strength concrete materials
  • the polymeric matrix usually being the designing parameter for pre-insulated pipes according to the described single pipe system.
  • the object is obtained by the pre-insulated pipe, where the pipe is characterized in that it comprises a layer of polymeric material blended with high strength concrete material such as Densit® ultra high strength concrete materials, at least partly surrounding the flow line being permeable to water or water vapour, and having significantly better barrier properties than PE, for resistance against diffusion of oxygen and carbon dioxide.
  • high strength concrete material such as Densit® ultra high strength concrete materials
  • foaming agents such as cyclopentane for producing of polymeric foam from e.g. polyurethane and styrene foam.
  • the cell gas composition will contain a significant amount of carbon dioxide and pentane, where the carbon dioxide is primarily generated during the foaming reaction process.
  • the layer of polymeric material or mineral insulating material has a resistance against diffusion of oxygen and carbon dioxide being better than perhaps 5 times and preferably 10 times the same resistance for a similar layer of concrete comparable with the water vapour resistance of PE, being measured according to any accepted test methods such as ASTM F-1249-90 : 38 0 C, 90%RF, ASTM D-3985-81, 23°C, 0%RF and DIN 53380 part 1 1982, 23°C, 0%RF.
  • a one layer solution not only provides an impermeable insulation coating, it also provides simplified joint solutions as well as insulation properties independent of the water depth as the impact from the outer pressure is related to the high strength concrete material such as Densit® ultra high strength concrete materials.
  • the nature of the mineral material such as ceramic spheres, glass bubbles, Leca or other spheres improves the mechanical stability and strength of the high strength concrete materia! such as Densit® ultra high strength concrete materials.
  • Densit® ultra high strength concrete blends easily reaches a level of 20 to 50 MPa depending of the blend which enhances the application parameters for deep-sea pipe laying enabling the tailored insulation blend of which the polymeric matrix usually being the designing parameter for the strength, the weight and/or the insulating properties. Similar application parameters is just as valid as for blend not only comply with the required insulation, but also tailored to have the right density to accommodate necessary weight coating.
  • High strength concrete material blends such as Densit® ultra high strength concrete materials blend with polymeric insulating materials offers similar properties.
  • the pipe is characterized as a layer of material according to claim 1 at least partly surrounding the coating of the flow-line, having the suitable bonding strength to the typical FBE (Fusion Bonded Epoxy) or other coating material enabling the complete insulation structure to be integrated with the pipeline material.

  • the invention may be tailored with respect to different blend criteria of the needed application parameters of which the single insulation layer is applied.
  • Another effect of the invention is that the sensitivity to cracks is very low in the outer insulation layer during bending the flow line during pipe lay, and does not cause any hazard to the insulation as the insulating material is embedded in the high strength concrete material such as Densit® ultra high strength concrete materials and is thereby unaffected by the water filled environment created during cracking condition.
  • the magnitude of the cracks is insignificant as the cracks are expected to close when the pipeline is straighten out.
