BE-15 Pipes and Materials: Welding of Plastic Pipes

Heating element butt welding

Preparatory work for welding

The welding area is to be protected from unfavourable climatic influences (e.g. moisture and temperatures below +5 °C).

The following measures may help to achieve this:·

  • preheating,
  • covering under canvas
  • heating

In order to prevent stresses due to differing temperatures such as the influence of the sun, temperature equalisation should be achieved by covering the region of the welding seams on time.
