Hdpe Pipe - Lorentz PSk2-7 Manuel D'installation Et De Fonctionnement

10.2.3 HDPE pipe

Option 1: Weld a tee-piece into the HDPE pipe, cf. ""Figure
44: HDPE pipe tee-piece" below. The tee-piece must have
a 1" female thread (G1", whitworth pipe thread). The pipe
diameter of the fitting should be the same as the pipe size.
This piece will be welded into the pipeline.
The tee-piece described above is not delivered by LORENTZ.
Option 2: Install an additional piece of steel or stainless
steel pipe with flanges on both sides of the HDPE inlet pipe-
line, cf. "Figure 45: Steel flange with adaptor in HDPE pipe"
below. Weld the steel/stainless steel adaptor for the water
sensor on the steel/stainless steel pipe according to chapter
"10.2.2 Steel/Stainless steel pipe" on page 60.
The steel / stainless steel pipe is not delivered by LORENTZ.
After completing of option 1 or option 2 continue with
step no. 2. of chapter "Pipe system – We advise that pipe
expansion joints are used close to the pump on both inlet
and outlet to reduce noise and vibration (cf. "Figure 36:
Pipe expansion joints" on page 54"). It is recommended
that you install a gate valve in the suction and discharge
pipeline close to the pump to avoid draining of the pipe
while cleaning (e.g. filters), repairing, servicing or replacing
the pump system.
