Field coating / top coating

To ensure that FCM-S coated pipes have the necessary load-bearing strength, the field coating of the factory-applied 3-layer coating should be carried out using a polyurethane casting system or GRp recoating. 

With FCM top coats, just as with plastic coatings, the transition area between the mill- and the field-applied coatings must be as even as possible without any great cross-sectional variations. So careful application of the field coating systems is very important.

When pulling in the pipes, care must be taken to ensure that no excessive loads occur. This applies, for example, to the support on roller systems when pulling in pipe strings; the respective permissible pressure loads of the external protection must be observed (point supports for entire partial strings are not permitted).
