Re: [MW:9083] Re: Repair of Body cracks for A 217 Gr WC6

Dear All,

Thanks for the valuable suggestions. Looking to the risk involved and the time period required to carry out the repair we have decided to put in a globe valve to control flow temperorily (as process allows for it) and to procure new valve body.

Thanks again,

Vinod
