[MW:899] Re: Comparision of UT & RT ( Justifying UT )

His, Sachin

 

Thanks for reply.

 

There is requirments in contractual documnets of project. I am talking about Hydro power project. It include components like  Turbine,Generator, Valve etc..

 

Normaly the grade of material for plate - A516, A283,SS304 ( Thickness renging from 10 to 250mm ) & Casting - A743 CA6NM  

 

We never conduct RT in manufacturing yet. So to convince client we required general comoparison stating to UT against RT.

I am great thanksful if you can provide the comparision considering below factor. cost,time dellivery ( OTD ),Saftey,sensitivity etc..

 

Revert back soon , Queries are invite

 

Thanks,

 

Vikas Rana

Dear Vikas,

You have ask question in very broad prespective.

Their are many reason to say RT is better that UT.

But to convice exactly opposite to your client you need to give some more details like

1.Type of material i.e pipe or plate
2.Size-Thickness,Dia.....

Above all design code

Note that if design code ask for RT then in no way u can escape from RT unless code give relaxation in case of joint whose RT is not possible due to complex joint configuration.

Sachin
