bauku extrusion technology
the original since 1956

The profilline s-series extrusion line is designed for a highly flexible production and can handle a lot of different pipe diameters.

 profilline s-4000: diameter range DN 800 to DN 4000

The extrusion lines can be equipped with one, two or three winding stations to increase the efficiency and production capacity of the machinery. Each winding station is able to handle all sizes of mandrels within the designed diameter range. This technology is also ideal for small quantities of one order (one pipe size and profile), as you can produce different diameters and a different wall thickness on each winding station, one after another. 

This is the technology you waited for: A low investment compared with conventional axial extrusion machines, combined with the flexibility and efficiency to handle smaller projects. 

High inside pressure solid wall pipes

With our spiral winding technology, it is possible to extrude large diameter solid wall pipes made from PE100. In order to save material and at the same time to increase the pressure resistance, we also offer the possibility to use a composite pipe made from PE100 and GRP or PE100 and steel.

The first extruded layer of the pipe is always a solid wall profile made from 100 % PE100, a co-extruded coloured strip might be included. The extrusion line will automatically add layer by layer, until the final wall thickness is reached. If a GRP or steel layer shall be included, these materials are inserted in the extruder die head and are winded in the middle of the pipe wall.

PE100 is number one for inside pressure, it has a high crack resistance, it is corrosion resistant, flexible and is certified for drinking water. Of course PE100 can be recycled by 100 %.
