How to carry out on-site repairs for flanges with a diameter of DN3000 that have become deformed? One of our company’s devices has a pair of flanges that have become deformed; the specification of these flanges is DN3000； It is a pair of flanges manufactured to PN4.0 standard according to HG20597 MFM; various gaskets have been tried, but leaks still cannot be eliminated. Due to special installation constraints, it is not possible to disassemble them for maintenance, so repairs must be carried out on site. I want to handle it on-site now; how should I do that? If anyone is willing to discuss this with me, please contact me on QQ at 20494485; please leave your contact information when adding me.
Using a flange cutting machine, the flange sealing surface can be repaired to be flat without the need to disassemble or assemble the equipment, thereby ensuring proper sealing.
