Welding tables for butt fusion of PE and PP pipes up to Ø1200
Heating time, changeover time and cooling time for PE (DVS 2207-1) and PP (DVS 2207-11) by wall thickness, from thin pipes to Ø1200. The values come from public sources.
Find the tables in the interactive tool
The welding tables for butt fusion of PE (DVS 2207-1) and PP (DVS 2207-11) have moved to the Welding tables tool, where you select material, diameter and SDR and get heating time, changeover time, pressure build-up and cooling calculated - also for coated pipe such as ProFuse RC and SafeTech.
In brief: the root of the tables is the pipe's wall thickness (e), not its diameter - the rule of thumb is e = Ø / SDR, and the heating time is approximately 10 seconds per mm of wall. The tables apply under normal conditions (around 20 degrees, a wind-free tent, clean and squarely faced ends), and the manufacturer's table always takes precedence where it differs.
