Translating Customer Needs Into Product Features

A handmade sketch was developed by Unareti with PLASSON, identifying the solution for the 125 mm line (the most critical one in terms of dimensions), shown in the attached sketch: the use of two 32 mm 45° elbows and three segments of 32 mm PE pipe provided the right geometry of the vent line as close as possible to the extension spindle and accessible through the
manhole.

Bill of material–supplied as a kit to be installed onsite, allowing flexibility in adapting to potential local constrains — includes:

All components are available in PLASSON catalogue or on the market, except the fitting for pressure gauge, which had to be co-engineered by the two teams.
After reviewing different alternatives, the best solution for fitting for pressure gauge was identified as a segment from a machined PE rod, bored with a 1/4” threaded nickel-plated brass insert and completed with a male plug with an O-ring, to seal the connection when not in use; the fitting comes with a protection cap, preventing sand/dust/etc. to affect the connection.
Unareti tested the fitting for pressure gauge by means of several decohesion tests, performed according to UNI 10521 standard, with a positive outcome.
