Pipeline heating before backfilling
Pipeline heating before backfilling
(OP)
I need to install thick pipeline in very cold environment (-30C). Longitudinal stress due to thermal expansion (working temperature is 80 degree) is making the overall stress analysis non passing. Therefore we ere thinking to heat the pipeline after laying and before backfilling to reduce the thermal expansion in restrained condition and decrease the longitudinal stress.
Did anybody experience something like this?
