OVERVIEW Rigid polyurethane foam systems It is a material with a proven track record for for pipe insulation reliability, durability and efficiency. Versatility is demonstrated by the ability to insulate over Rigid polyurethane foam has been used for an extremely wide range of temperatures, the insulation and protection of pipes for more from the extreme cold of -196°C to the than 30 years. It is now more widely used intense heat of more than 150°C. than ever, increasingly displacing alternative materials. One of the most popular areas of It is also suitable for applications ranging use is for district cooling systems, where it is from small plumbing pipes 10mm in the insulant of first choice for many specifiers. diameter, up to the largest heating pipes with Other common uses are in: 2,000mm diameters and 250mm of insulation

1) On and offshore oil and gas pipelines thickness. 2) Heating and plumbing services for power stations, chemical plants and refineries Pipe manufacturing techniques for 3) Dairy industry applications effective insulation 4) District heating systems There are two main forms of pipe production 5) Other special applications i.e. swimming techniques; discontinuous and continuous. pool pipelines The method adopted by an individual manufacturer will reflect the particular operations and applications of that company’s business.

Polyurethane foam’s popularity is based on its outstanding insulation properties, which prevent heat loss, or alternatively maintain temperatures in cold environments to prevent freezing or cracking. These energy Discontinuous pipe manufacturing conservation qualities improve the overall techniques cost efficiency of customers’ networks. Discontinuous manufacture involves filling of the void between, typically, a steel inner pipe Other important characteristics include high within a high density polyethylene (HDPE) mechanical strength, adhesion, flexibility and casing pipe. The gaps at both ends of the good flow-ability, necessary for the consistent pre-assembly are sealed with tightly fitting fill and insulation of pipe sections. caps equipped with injection and air venting holes. Standard steel pipe lengths for this process are 6 m and 12 m.

p. 03 / 04 Why polyurethane is an excellent Adhesion insulant During the short period between mixing Rigid polyurethane foam demonstrates and final curing, rigid polyurethane foam is versatility both through its physical strengths extremely adhesive, which allows it to bond and mechanical properties. These qualities effectively with a wide range of building enable it to be used in a wide variety of facings. The adhesion is so strong that the multi-functional building products which strength is usually higher than the tensile or combine insulation with load-bearing, sealing, shear strength of the foam. impact resistance, weight and space-saving, together with ease of maintenance. Compatibility Rigid polyurethane foam is compatible Low thermal conductivity with a large number of building facings, Rigid polyurethane foam has one of the including paper, foil, glass fibre, aluminium, lowest thermal conductivity ratings of any plasterboard, plywood and bitumen. These insulant, which allows efficient retention can complement the inherent strengths of the of heat or, alternatively, maintenance of a foam, enabling use as semi-structural panels refrigerated or frozen environment. and cladding and allowing foam to accept cosmetic finishes such as plaster to operate effectively as moisture barriers in conditions of high humidity.

Strength Rigid polyurethane foam provides a high level of compression and shear strength, which is bond enhanced by bonding with facing Water absorption materials such as metal or plasterboard. The water vapor permeability of rigid polyurethane foam is low and is enhanced Processability in most building applications by the Rigid polyurethane foam can be made either incorporation of a moisture barrier of under continuous block or batch factory polyethylene film or aluminium foil. production, or by on-site mixing for spray and injection purposes.

In-situ stability Rigid polyurethane foam can be used in applications which experience exceptional extremes of temperature, from -200°C to +100°C. Rigid polyurethane foams are usually used Polyurethanes are flexible foams used in at lower thicknesses than other insulants, mattresses, chemical-resistant coatings, which means that their heat or fuel contribut adhesives and sealants, insulation for ion to a fire is low compared to other, buildings and technical applications like heat thicker insulating materials. The overall fire exchangers, cooling pipes and much more. performance of an insulation panel can be significantly enhanced by the material that is The relation between temperature and used to face the panel - for example, steel. thermal conductivity is indicated in the diagram below: Independently monitored, large-scale tests of buildings incorporating rigid polyurethane T(°C) = 5/9[T(°F) - 32] and polyisocyanurate (PIR) foam insulation carried out in the USA and Europe have concluded that, properly used, these materials do not add to the severity or serious hazard of fires.

Lightness At low densities (e.g. 30kg/m3), the volume of polyurethane polymer in rigid polyurethane foam is around 3 per cent. The remaining 97 per cent of the foam is gas trapped within the cells, which provides the low thermal conductivity properties.

The lightness of the foam is an important aspect in terms of transportation, handling and ease of installation.

Chemical resistance Rigid polyurethane foam provides excellent resistance to a wide range of chemicals, solvents and oils.

PU Factor Polyurethane is an organic polymer formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.
