I have had experience with elastomer lined pipe that is prefabricated and then
lined followed by field welding using a special fitting. I this case, the heat
of welding does not damage the lining.

unlined pipe. If the already lined pipes are to be joined by a circumferential
seam. There has to be set back of unlined area, so that the heat of the welding
does not damage the lining. The unlined weld and offset are then to be completed
by a repair method. You should be able to find enough material on this on the
net.
