EXTERNAL CORROSION OF A PIPELINE​Pipes can corrode externally due to exposure to the environment. If the pipes are above ground they will require a suitable barrier coating to prevent atmospheric corrosion. ​When pipelines are buried, corrosion […]

Thus, simply measuring the potential of the structure will demonstrate whether complete protection is being achieved.​Consultation with a […]
