PIPE LINER AND METHOD OF INSTALLATION |
摘要 |
A method of relining sewer lines (2), waterlines or gas lines is disclosed which uses a segmented liner (8) of reduced size relative to the pipe being relined, with the liner being heat/pressure molded to the shape of the pipe (2) being relined. The liner segments (4) are joined by conventional joining techniques, however, the preferred joint is achieved by fusion. |
