Application
Repositioning of a series of flanges in the pipework of a cooling system (manufactured by others) in a combined cycle power station.
These flanges were left out of place after the laying of the concrete floor, resulting in difficulty with subsequent connections.
Characteristics
Specifically, these four flanges of 1350mm diameter, were displaced from their intended position by up to 115mm horizontally and 80mm vertically. Two separate inserts of 450mm diameter were also out of position.
PH Technology was responsible for repositioning the flanges and joining them to the pipes, leaving the system ready for subsequent hydraulic testing.
Operating Conditions
The hydraulic tests were fixed at a pressure of 6 bar.
Material
The repair was carried out using a bisphenol-A type vinylester epoxy resin FRP DERAKANE 411/350 throughout the laminate.
