Some trends in the design and construction of steel penstocks at hydroelectric stations
Conclusions 1. Scientific-technical progress in the area of penstock construction should proceed in two directions: a) increasing the effectiveness of the designs of steel penstocks to provide a substantial increase of reliability and durability; b) creating a new mechanized technology for constructing penstocks with the use of modern pneumatic and hydraulic devices. 2. The technical and economic effectiveness of using high-strength steels in comparison with steels of ordinary quality and the usual low-alloy steels consists in the reduction of weight and increase in bearing capacity of the penstocks and their durability owing to less wear, increased strength, corrosion resistance, and cold strength. Along with a considerable saving of metal the labor intensity of manufacture and cost of the structures as a whole is decreased. The cost in this case decreases both as a result of the reduction in the consumption of steel and due to a decrease in the cost of transportation and assembly. 3. Of importance for penstocks embedded in rock in straight sections is the size of the rock-penstock space, which should be minimum, which will minimize the volume of rock excavation and concrete in this space.
