Welding of thermoplastics - Heated tool welding of pipes, piping parts and panels mase of PVC-C
|Publication Date:||1 November 2012|
|ICS Code (Welding processes):||25.160.10|
Scope of application
This technical code applies to the heated tool butt welding of panels, pipes and piping parts made of PVC-C.
The PVC-C panels are used for the fabrication of storage and process tanks and miscellaneous construction elements by means of heated tool butt welding. These components are predominantly utilised in the field of the storage of liquids and solids as well as in the field of process chemistry.
The PVC-C panels and piping parts must comply with the DVS 2205-1 technical code, Supplement 9 and Supplement 11, as well as with the properties specified for compounds in ASTM D 1784-03, Cell 23448. The Vicat softening temperature must exceed 105°C.
The fittings made of PVC-C must exhibit the same properties as the piping. If these are not available, it is recommended to fabricate these from pipes. Piping and fittings predominantly serve to transport liquids, gases and solids.
