[1771978]

Hi,

We have bucket type mesh filters installed at our plant after the furnace where we have VCM in addition to craked EDC , HCL and some amount of coke. Filters are of SS 304 and mesh size is 20, installed at pump suction. However, whenever we open them, mesh found dislodged from its body and damaged from various places in addition of coke in filters. Can anybody will help me out in this issue
