5.0 Preparatory Steps:
Select proper MDS Stopper from the sizing table in Section 4.0.
Select proper fitting from the sizing table in Section 4.0.
Attach selected fitting, based on pipe material, per company standards and specifications.
Before welding steel fitting on main, remove the blind flange, gasket, and plug from fitting.
Kleiss Gastool PE fittings use a 4.0 mm fusion pin. Ensure you have the appropriate tips/adapters on your
electrofusion processor that will fit the 4.0 mm pins.
When installing PE fittings, as part of the electrofusion process, make certain to allow the fitting to completely
cool down for the entire “cooling time” before tapping the main.
Pressure test attached fitting per company standards and specifications.
6.0 Tapping Operation:
Attach slide gate valve, with gasket in place, to
fitting outlet using nuts and washers.
Check gasket.
Attach pressure equalizing hose to slide gate
valve.
Use valve wrench to check if slide gate valve
opens and closes.
Take the tapping device out of the case and inspect
the device visually for irregularities. Make sure
the threads are clean and the device operates
freely.
