Shielding Effect of Delaminated Pipe Coatings

Position Statement by German, Austrian and Swiss associations dealing, inter alia, with cathodic corrosion protection
News - 26.04.2019

In the context of cathodic corrosion protection, the shielding effect of delaminated coatings is frequently discussed. Especially in Anglo-Saxon countries, the use of non-shielding coating systems is prescribed for certain pipelines. This increasingly leads to the supersession of polyethylene-based coating systems in these countries. In recent years, discussions with regard to shielding are also increasingly taking place in Europe, accompanied by the increasing marketing of allegedly non-shielding products. However, the use of coatings with significantly poorer dielectric properties contradicts Central European practice.
