| | Object: | Stone Press 3 | | Design pressure: | 230 barg | | Diameter: | Ø 880 mm |
Problem definition The tread of the valve (M470) turned out to be leaking after 30 years of produciton. During the repair a crack was discoverd. In short notice a repartion principle had to be proposed. So the standstill period could be as short as possible.
Contribution of Stemar Engineering In the first stage Stemar Engineering made a stress calculation with fatique incorporated.
After the crack was found we advised the Tata-project team with the possibilities for a durable repair. Because of the high amount of cycles and high pressure with large diameter, fatique and forces played an important role. Result After the successful repair press 3 is back in production.
