Abstract
A flexible pipe covering having a seam or split along its length is placed over a water or like pipe. The seam is sealed by the use of a pressure sensitive adhesive transfer tape which is factory mounted on one side of the seam and provides a protective sheet that is removed after the flexible pipe covering is mounted in position. Upon removing the protective sheet, the pressure sensitive adhesive will be made to contact both sides of the seam and seal the seam. A similar type of adhesive joint may be formed at the butt end of two adjacent pipes.
