초록

A metal pipeline section that has a metal flange at one end is lined with a plastic liner such that some of the liner extends beyond the flange end of the pipeline section. An annular plastic member is electrofusion joined onto the outside of the portion of plastic liner which extends beyond the flange end of the pipeline section and any liner extending beyond the annular plastic member is trimmed off to make the liner flush with the annular plastic member. The annular plastic member is then positioned adjacent the annular plastic member of another simil...
