KraussMaffei Berstorff receives foam insulated pipe machine orders

KraussMaffei Berstorff, an extrusion machinery supplier, said Technopark, a Russian plastic pipe producer, has recently ordered a complete PUR-insulated pipe production line.


The Russian company is an important pipe manufacturer which operates several extrusion lines to produce a wide spectrum of pipe grades for different applications. Technopark is now expanding its production capacity with the new system from KraussMaffei Berstorff, which it will use to produce pipe for district heating systems by encasing media pipes, made of crosslinked polyethylene, with polyurethane foam insulation and a PE outer sheath.

The line is engineered for continuous production of insulated pipe. The media pipe is unwound continuously from the steel drums, on which it is supplied line, centered as it passes through a retarder and fed into the foam-contouring unit. The pipe is encapsulated with PUR foam, a PE sheath is applied, the product is cooled and then wound onto rolls as it emerges from the haul-off. The biggest insulated pipe systems produced on this line have an outer diameter of 180mm; the diameter of the media pipe itself is 110mm.

With very low manpower input, this process delivers production speeds of up to 5m per minute. The district heating pipe systems that come off the production line can be laid very easily, quickly and at low costs.
