Global opportunities in Pipe in Pipe technology

An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing performance are becoming more stringent. As a consequence, polyurethane preinsulated pipe manufacturers are faced with increasing demands for low energy consumption pipe networks and higher thermal resistant pipe composites for industrial applications. Huntsman Polyurethanes has developed a new generation of polyurethane foam system technology with a significantly reduced lambda value. The use of this system improves the cost effectiveness of the pipe network over the service period of 30 years, due to the reduction of heat loss. This new system can be processed with conventional production techniques. The use of polyurethane preinsulated pipe composites in industrial applications offers clear advantages compared to the traditional in-situ installed insulation, e.g. less water or steam ingress and subsequently less corrosion. Huntsman Polyurethanes has developed new high temperature resistant polyurethane foam. Together with traditional discontinuous production techniques, this new foam system will enable easier installation and higher reliability over longer periods.
