Metallographic Aspects Investigation of Penstock Materials in Hydroelectric Power Plants and Penstock Maintenance Methods
Öz
Hydroelectric power
plants are renewable energy sources and have little impact on the environment.
Therefore, it is one of the most preferred energy sources in the world. In
parallel with this situation, it is very important that the hydroelectric power
plants are maintained, their failures are prevented or permanently removed. One
of the most important parts of hydroelectric power plants is penstock pipes.
Along with the snail part of the power plant, the penstock supplies the
pressurized water to the turbine wheel for energy production. In the power
plants that have been producing energy for many years, the maintenance and
material properties of penstock are very important. In this study, one of the
most important equipment of hydroelectric power plants, pressurized water pipes
(penstock) and chemical components have been examined in macro and micro
structure and their maintenance is investigated. In the metallographic study on
the samples taken from two different regions of the penstock pipe; the perlitic
structure, which has a homogeneous distribution into the ferritic structure
forming the matrix, is determined and supported by analyzes. This study will
help to ensure that all hydroelectric power plants operate smoothly in terms of
penstock.
