Re: [MW:10396] Which is better material for Seat / Control Valves / Sour Service

Hi,

Stelliting is done for hardness purpose to avoid wear due to friction durings its operational life

Hence stelliting cannot be replaced with SS316

Dear Experts,

 

The Data sheet for Control Valve calls for Seat Material of Trim as Stellite 6 + ENP and Supplier is offering SS 316.

Whis is better - Is it Stellite 6 + ENP or SS 316?

 

Info: Service to be used is Sour Service.

Temperature : 60 Degree Centrigrade

Inlet Presure: Max. 0.5 bar g

Otlet Presure: Max. 0.3 bar g

 

Appreciate to see response ASAP.

 

Regards

VPV
