Partnership with Baosu for groundbreaking PVC-O pipe technology. KraussMaffei Berstorff is introducing PVC-O pipe technology together with Baosu Pipe Industry at Chinaplas.

After signing a cooperation agreement at the end of 2017, KraussMaffei Berstorff and Baosu Pipe Industry (Hebei province, China) are actively pushing the international sale of their PVC-O technology.

Baosu is a specialist in PVC pipe extrusion that has concentrated on the development of special stretching technology over the course of many years,” says Andreas Kessler, General Sales Manager at the Munich location. KraussMaffei Berstorff has maintained a strong, long-term customer relationship with Baosu since the eighties. Among other developments, it will contribute its twin-screw extruder for U-PVC production based on the latest technology to this cooperation as a core component.

In order to respond more quickly and with more precision to customer demands regarding process engineering and material composition, Baosu Pipe Industry is planning to install a system, equipped with our twin-screw extruder that will be used for demonstration purposes” explains Kessler. Compared to non-oriented PVC pipes, biaxially oriented pipes achieve nearly twice the impact resistance, higher internal pressure resistance and a weight reduction of up to 40%.

The pipes will predominantly be used for wastewater and drinking water supply. Here in particular, they exhibit an excellent combination of sustainability and outstanding technical properties. Transporting and laying these pipes is also easier. Baosu Pipe Industry will market the finished product under the brand name Taiji Blue pipe®.

Baosu®, founded by highly skilled engineers in plastic pipe field, is an innovative and leading company devoted in the development of PVC-O technology and PVC-O pipes. This revolutionary PVC-O technology provides more reliable and greener solutions for the water transmission and distribution industry. Baosu is the first company of certified PVC-O pipes in China.

Baosu® business is developed in two divisions:

  • TaijiBlue® PVC-O Tech focuses on the research and development of PVC-O extrusion and orientation equipments.
