- Abstract
- The control parameters of the thermal process of welding polypropylene pipes at air temperatures below the standard are the duration of preheating and cooling for alignment of temperatures and the dimensions of the heat-insulation chamber. Techniques for determination of the control parameters are offered. Parameters are determined from a condition of flow of thermal process at low temperatures by regularity to the close dynamics of the temperature field in welding under the permissible ambient temperature.
