WELPING FIELD PARAMETER TOOLS
PE Butt Fusion Parameter Tools
Select the standard required by the approved project welding procedure. The DVS and ISO calculators are independent tools and their pressure or timing values must not be interchanged.
DVS 2207-1:2015-08
- Interface pressure: 0.15 ± 0.01 N/mm²
- Heater: 220 ± 10°C
- Cold, mid, and hot cooling bands
ISO 21307:2017
- Interfacial pressure: 0.17 ± 0.02 MPa
- Heater: 225 ± 10°C
- Cooling under pressure referenced to 23 ± 2°C
Use the project-specified standard
These are field calculation aids, not official reproductions of either standard. Confirm pipe material, machine, measured wall thickness, drag pressure, ambient conditions, and the approved WPS before use.
