New generation of GRP pipes

HOBAS Pipes has launched a new product line, featuring a particularly durable inner protective layer. The standard centrifugally cast HOBAS GRP Gravity Pipe has also been further improved to suit a broad variety of applications even better than before.

Resistant to abrasion and corrosion, the new HOBAS Top Performance Pipe’s durable inner protective layer made of polyurethane resin, the thickness of which is customised for each project individually, typically starting at 2 mm. Thanks to its particularly smooth inside surface, it also features excellent hydraulics and prevents sedimentation. With their special properties, HOBAS Top Performance Pipes are suited for a very broad range of challenging applications: From main sewers and sewers with retention function to drainage pipelines with very high slopes, culverts, efficient pressure pipelines, and industry applications. Apart from the thickness of the inner protection layer, the wall structure of the centrifugally cast (CC) GRP pipe can also be customized for special project conditions. Comprehensive examinations in the internationally recognized HOBAS TechCenter in Austria confirmed the pipes’ unique performance in e.g. long-term deflection and strain corrosion test settings. And the top-performing CC-GRP pipes have already proven their worth in real-life applications: In Switzerland, they help to safely transport storm water containing sharp-edged stones and debris.
