It is often a time-consuming and expensive process to replace worn out pipes. In addition to operational shutdown, it is often made significant interventions in buildings, like living quarters, structures etc. While this work is in progress, (production) facilities must also be closed down with all the costs that this entails.
United Pipeline Services’ business idea is to offer renovation of existing pipes. The advantage of such a solution is faster project execution and thus a shorter downtime. In addition, the total cost will be significantly lower.
How does our solution work? Using compressed air we install a textile/felt liner in the pipes to be renovated. The liner is saturated with our specially developed epoxy resin. When installed, it is flexible and closely follows the curves of the existing pipe. Bend on the pipes also creates no problem.
When the liner is in place, it is cured by hot water or steam under pressure. The result is a new rigid tube. The liner is only a few millimeters thick, so the inner diameter of the pipe is minimized. The new pipe also has a smooth surface which minimizes the friction and increase the flow. The renovated pipes will be just as good as when the pipes were new.
This method has been used for the renovation of drainage pipes for a number of years. New technology means that the applications have recently grown significantly. One of the company’s most important areas of focus is therefore to offer renewal of pipes, nozzles and lamination of tanks, wrapping of deluge pipes at offshore installations where safety is most important – and shutdown is expensive. Other areas of focus are spools and caisson in prefabrications.
