Abstract
Superior performance characteristics of polyethylene tape coatings are insured when tension is applied to the tape during the wrapping process on pipe. The tangential force applied during the wrapping process creates an inward radial force, compressing the adhesive layer between the steel pipe surface and the polyethylene tape backing creating a gasket effect. Field and laboratory data show this gasket effect to influence cathodic disbondment, adhesion, and water absorption characteristics of polyethylene tape coatings.
