Hidden corrosion for gas companies

How to detect corrosion during insulation? It costs gas companies more than 100 million to detect corrosion, and they have therefore needed to develop a new solution for this.

CustomerFjellanger Detection & Training Academy, Equinor and Gassco
BackgroundFjellanger Dog Centre was started in Os outside Bergen in 1988 by Rune Fjellanger. They have their own department of service dogs, where they do training and developing search dogs. Equinor and Gassco are Norwegian oil and gas companies.


Specially trained dogs help Equinor and Gassco detect corrosion in piping systems.


The services we assisted with: Product development and plastic production.


When the project came to Grepi Plast in the autumn of 2012, form tools already existed, but they worked very poorly. Grepi Plast has in close cooperation with Fjellanger in 2013, made a comprehensive upgrade of the tools, as well as changed the material concept, and production is in full swing. Grepi has worked hard to succeed in this, and has signed a contract with Fjellanger for further production.


Statoil and Gassco, together with Rune Fjellanger from Fjellanger Detection and TrainingAcademy AS, have developed a method that can save the gas companies for 100's millions of kroner. The method also allows for the use of specially trained dogs for other large tasks. We are very proud to be part of this project and to produce the plastic components of the system.


The dogs detect corrosion by being exposed to air samples taken from pipes and tanks outside the plant, so that they then manage to smell their way to the pipes in which they may be in.

New requirements for corrosion safety and drainage capacity

SINTEF Byggforsk has new requirements for pipe-in-pipe systems for water supply in homes. The drainage capacity in a manifold cabinet should be at least 0.4 l/s and it should be corrosive. In 2015, Grepi Plast started the development of a manifold cabinet that would be adapted to new requirements in the industry.

Water damage, the largest type of damage suffered at insurance companies

/ / /
Water damage accounts for the largest type of damage among insurers. In a meeting between Pavels Innovation, Grepi Plast and Armaturjonsson, it was discussed how to prevent the water damage. The innovative solution was Arjonstop.

Corrosion in the pipes within the insulation

/ Offshore /
On offshore installations and onshore refineries and other petrochemical plants where there are large amounts of pipe streets, there is a challenge that corrosion may occur in the pipes on the underside of the insulation. There are various methods for detecting CUI problems, among other things. using X-rays and ultrasound, but this is complicated and cost a lot of moneys. The [...]
