Protective coatings and lined surfaces should be continuously monitored and controlled in order to detect any deterioration or damage as early as possible and allow for cost effective repairs. The protective coating is tested for intactness and thickness prior to perforation by means of optical and electrical inspection. A prerequisite for this examination is a clean, dry surface.
The amount of electrical voltage needed for testing is dependent on the type of surface protection. Guidelines referring to our testing equipment can be obtained on requested. There is the danger that the base material will corrode and suffer chemical damage if perforation in the protective coating is detected too late. The corroded material will need to be cut out and replaced should this have occurred. The protective coating can be repaired subsequent to this maintenance. Simple repairs can be carried out in-house (according to factory specification), large-scale damage can be repaired by our Repairs and Assemblies service.
