DUAL PRESSURE WELDING CYCLE
The Dual Pressure cycle is used when welding PE 100 with thickness equal or superior to 20mm.
When welding PE 100 with thickness inferior to 20mm, use the Simple Pressure cycle (previous page).
The first four phases are identical (with
respect to the simple pressure cycle).
Phases 5/6 Welding. The welding phase happens in two moments:
1. Keep both ends together at the (P

+P
t
) pressure for the entire t
5
time.
2. Reduce pressure to P
6
value and maintain the contact for the entire t
6
time.
Phase 7 Cooling. The joint must not be removed or suffer any sort of mechanical strain for the entire t
7
time.
