PU pipe coating

Solid PU pipe coating are merely applied for the protection of the interior surface of pipe lines transporting water or an abrasive media. PU foam pipe coating on the exterior of pipelines are added for thermal insulation purposes. Bauhuis has supplied several pipe coating plants for the application of both types of coatings. For the application of the foam on the exterior Bauhuis can offer various solutions like a continuous system involving a helical pipe conveyor or discontinuous system with a pipe coating buggy. In the later case the pipe is put with the outer ends on travelling pipe rotation unit and passes a stationary positioned spray gun. PU pipe coating plants are provided with all necessarily PU pipe coating equipment including a tank farm, temperature controlled day tanks, dosing equipment for adding blowing agent and a main mix pump with spray guns all provided by renowned suppliers.

Asphalt enamel pipe coating

Coal tar and bituminous based enamels have been applied since the 1940’s and 50’s and its advantages/ disadvantages in use are well documented. Although not applied in the same volumes as in previous years, mainly due to environmental concerns, the relative low price of the CTE/BA coatings compared to the for example widely used 3-layer means that these coatings are still being applied occasionally.
