Application of Butt Fusion Joint at Sites

(3) Electro Fusion Joint Step: (Use Electro Fusion Welding Machine)

\odot Clean and mark ■ Clean up the connection part, mark the inserting depth.

② Scrape ■ Scrape and polish the joint surface.

③ Align and restrain the fittings to the pipes

\circledast Apply electric current

■Apply the electric current to the fittings; the joining parts will be heated and melted, turn off the current when there is melt flowing in the observation hole.

\circled{5} Cool ■Cool without movement or pressure.

Note:Whilconnecting,theheatingvoltage andtime should complywithmanufacture'stechnical stipulationf ElectroFusionWeldingMachine.

(4) Transition Joint

Join the PE pipe and the iron pipe by Flange Joint

① Preparation

Prepare thenecessarytoolsand accessories. ■Checkandcleantheaccessorie: ② Put the pipe in the flange tray. ③ Use socket fusion joint or butt fusion joint on the pipe and the flange stub. \circled{4} Put the rubber ring between the two flange stubs, and then tighten the bolts.
