Shaping the future with innovations

Our specially founded 'Innovation' department makes it possible for us to meet our goal of providing our customers with advice and support with a view to a successful future.

For Flender, that means constantly analysing and optimising our customers' existing processes and applications, as well as developing new processes and products based on their needs. This includes supporting you with our expertise and making active, anticipatory suggestions regarding the latest technology.

This is how we are able to come up with new procedures and systems in a target-oriented manner, which are economically beneficial and efficient for our customers. One example of this was the development of our Flender-Flex-TubingĀ® 'endless pipe', which saves the customer on girth welds that are expensive to check, accelerates processing procedures and minimises laying costs on the building site.

A wide range of other procedures and products have also been developed since the emergence of the Flender INNOVATION department. We are currently working on a number of interesting new developments.

We would like to work with our customers to continue the process that we successfully started a few years ago regarding innovation and development and invest in a continuous process of joint further development for existing processes and applications. That is our goal; to continue in our role as your partner for high-quality premium pipes and profiles.
