[MW:3086] RE: 3083] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates

Dear friends ,

As per my suggestion, you better to select Co.60 only because the Ir -192 source is can do max .50 mm is sufficient but the code says can do upto 69mm .practically you can select the source Co -60 and you can save time as well as will achieve the sensitivity ,what the code and spec. recommended.

Nilesh, Why would you do these things? 1. No co60 for 69 mm SS? 2. High Strength and Low Strength Ir 192 are same in their pen power. 3. UT of 60 mm SS - well, can you please pass me the proc? I am curious. Twin crystal for what reasons?

But Ir 192 Penetration is same from Low and High. If am wrong correct me.   S.Senthilkumar --- On Sun, 30/8/09, Yadav Shiva <luvshiv2002@gmail.com> wrote: From: Yadav Shiva <luvshiv2002@gmail.com> Subject: [MW:3080] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates To: materials-welding@googlegroups.com Date: Sunday, 30 August, 2009, 2:38 PM hi,            you can go for high strength - 192, but dont go for cobalt 60 since we use for thickness ranging more than 100 to  & 150 mm above.

For RT you may need cobalt 60 or High strength iridium 192. For Ultrasonic Testing you shall use the RTD Twin crystal longitudinal wave Angle probes. Regards, Nilesh Pathare.
