摘要 |
<p>A welded joint of a lined pipeline has a main pipe and an extension piece having a generally tubular shape, an inner wall and an annular weld connecting the extension piece to the main pipe. A liner extends through the main pipe and partially into the extension piece. A compression ring includes a flange and a compression portion. The compression portion engages the liner internally and compresses the liner radially outwardly against the extension piece so that the liner is sealed with the compression ring.</p> |
