Krauss Maffei is represented in Oceania by HBM Packaging & Plastics Technologies .
Krauss Maffei Extrusion of Munich Germany, a world leader in plastics machinery is a popular choice for extrusion machinery among pipe manufacturers around the world.
With the production trend moving away from single-layer standard pipes towards multilayer pipes consisting of extra functional layers, Krauss Maffei is offering an innovative extrusion machinery technology that facilitates improved production processes as well as cost savings.
Turkey’s largest pipe producer, Pakpen Plastik Boru ve Yapi has a number of extrusion lines supplied by Krauss Maffei to produce PP-R fibre-composite pipes, which find several applications including the supply of hot water.
Three-layer PP-R fibre-composite pipes have some clear advantages over conventional hot water pipes:
- Hot water passing through the pipes results in only minimal longitudinal expansion, making the pipes easier to lay because the installer does not need to allow for expansion when selecting connecting fittings.
- The extra stiffness of the PP-R fibre-composite pipes means that the fixing clips can be spaced further apart compared to unfilled PP-R pipes
Three-layer foamcore PP pipes used in domestic applications offer weight and cost advantages over single layer compact PP pipes with the same dimensions and ring stiffness.
The lower density of the foam layer can result in raw material savings of over 20% compared to compact pipes. As raw material can account for as much as 90% of the total manufacturing cost of plastic pipes, the savings are quite significant.
Russian pipe producers Politek Pt and Politron as well as Estonian producer Gallaplast are some of the companies that are using Krauss Maffei extrusion machinery headed by a single screw extruder from the 36D series with multilayer tooling and material-specific calibration and cooling systems for production of pipes.
