The client reported leakage from periphery and ID of Gas Turbine.
Diaphragms were installed in the valves, but there were minor leakages from periphery & ID
The client required – Diaphragms which could sustain 10-15 barg gauge pressure
The requirement had to be fulfilled during the Covid pandemic.
The below steps were followed to design and manufacture diaphragms that would prevent the leakage.
• We developed a new mold
• Used Viton (FKM) rubber which is suitable for gas application
• Used high tensile fabric for strength of diaphragm
• We maintained 70/75 Hardness for the application
After installing the diaphragm there were no leakages and diaphragm could sustain the pressure. The order processed included 6 Viton rubber diaphragms. The client was satisfied with the development made and the products supplied were approved without any rework.
