Heating of polyethylene pipes in the construction of gas pipelines at low temperatures

Abstract

This paper proposes a method for the determination of the duration of heating polyethylene pipes in coils by heated air during the installation and laying works in the construction of gas pipelines under the conditions of low temperatures. The mathematical model of thermal process of heating polyethylene pipes by heated air is considered. Calculation results on the heating duration of a polyethylene pipe are given in the range of external air temperatures at a known flow rate of heated air supplied inside the pipe.
