According to EuropeanPlasticsNews.com, KraussMaffei Berstorff, a subsidiary of the KraussMaffei group, is supplying a system for continuous production of PUR-insulated pipe to Russia-based Technopark.

Technopark, a plastic pipe producer headquartered in St. Petersburg, will use the system to make pipes for district heating systems. The pipes are made of crosslinked polyurethane with polyurethane foam insulation and a PE outer sheath.

“The current drive to reduce energy consumption, including capturing off-heat, and to exploit geothermal energy sources and biogas can be expected to produce strong growth in demand for production systems to make insulated pipe,” Michael Hofhus, manager of the pipe product group at KraussMaffei Berstorff, said in a statement.

The manufacturing system is designed for continuous production so unwinds media pipe from the steel drums which is then fed into a foam-contouring unit. Once the PUR foam is applied, the pipe is cased in a PET sheath. Finally, the product is cooled and wound onto rolls.

These pipes are cheap to lay and the number of joints required is reduced, says KraussMaffei. Problems such as leakage and thermal bridging are virtually eliminated, adds the firm.
