Hi Anant,

Yes, a wear plate is recommended on the core pipe where steam is entering from the jacket. This plate can be 3mm thick, 50mm X 50mm size. This plate shall be of the same material of the core and shall be welded before the hydrotest of the core.

Thanks Paul, you are really acting fast.

Regards,

GSN Murthy.
