Coal-Tar Enamel & Bitumen Coating and Lining

Following the blasting application, primer is applied to the pipe surface which is providing an adhesion between the pipe surface and the coating layer. Wrapping method is used for the external surface of the pipe and centrifugial method is used for the internal surface of the pipe. The glass fiber is embedded into either hot bitumen or hot coal-tar enamel and then wrapped on the pipe surface.

After completion of the coating process, the bitumen coaed pipes are lime washed and the coal-tar enamel coated pipes are wrapped with rock shield material. These kind of coatings are preferred due to the low cost commonly in the external coating of water line projects.
