constructed by transporting the half-pipe parts to the site, welding the parts into 3 m-long unit pipes and then into 15 m-long unit pipes in the temporary workshop at the site, and installing in the inclined shaft and welding the unit pipes. The installation of steel penstock in the inclined shaft was a critical path of the construction schedule.
HYDRO MECHANICAL EQUIPMENT SUPPLIER ATB groupThese penstocks can withstand very high heads using relatively thin plates that are easy to weld and install on-site. As an example, the penstock of the ENEL-San Fiorano hydropower plant, 2.15 m in diameter, resists a water head of 1,418 m.
