HOBAS Research & Development

It counts among the world’s most modern centers for research and development of GRP pipe systems: The Amiblu Technology Center in Sandefjord (Norway). Here, our experts continuously monitor the long-time performance of various Hobas products, work on new product lines and improve existing ones. Our main concern is to ensure highest possible customer benefit.


Since the production of the first Hobas pipes at the end of the 1950s, Hobas experts have been constantly advancing the technological development of products, raw materials and production facilities. Today, Hobas pipes are further developed and tested in the world’s largest certified GRP pipe laboratory in Sandefjord, Norway. By  means of more than 30 different testing methods we make sure to offer our clients only the best, thoroughly proven solutions.


The Amiblu Technology Center is certified by the Norwegian Accreditation according to ISO 17025. The laboratory is equipped with state-of-the-art facilities for testing even very large components of up to 4 m in diameter. Internal pressure, ring stiffness, tensile strength, corrosion resistance under strain and stress, abrasion resistance, analysis of raw materials, regression and process analysis – the tests conducted are as impressive as is the longevity of Hobas products: depending on the application, independent certification institutes confirm a service life of more than 150 years.
