Tight lining (size reduction via roll down or swage lining)

2016-8-3  Tight lining (size reduction via roll down or swage lining) When is it used and what are the benefits? Tight lining is a process that temporarily reduces the size of the new pipe, enabling it to be drawn into the degraded pipe. Once inserted, the PE pipe expands to create a tight fit with the old pipe, minimising reduction in flow capacity.
