Re: [MW:22711] Tube to tube sheet mock up qualification

Hi Silambarasan ,

If the welding is for ASME Sec VIII Div -1 Vessel, then test Macro ( for MLP check ) , PT, Visual. This is enough as per ASME-IX QW - 193 requirements.

Hardness & RT are Special Tests as per Client requirements only, inorder to judge the hardness value . Quite Stringent too.

Pull out & Tear tests are required for Sec VIII , Div-2 Vessels, If I am not mistaken.

Do you have Client Spec to weld this MockUp ?

Read again ASME-IX,  QW 193. 1 to 3 for MockUp testing requirements and you must read QW-288 for Essential Variables to follow during Qualification.

Regards,

Saravanan

Dear members,

We are going to carry out a Mockup Procedure qualification for T-TS joint as per ASME SecIX. what are the test required to carry for the qualification. I hear from a TPI that RT, Tear test & pull out has to be carried out, whereas ASME Sec IX & Tema class 'R' are not talking about the above said tests. 

Is the above said tests required? If so, the as per which standard?

Kindly advice
