Re: [MW:28583] golden weld joint require ments

Dear Gulam, 

There is No specific standard says that 100% DPT requirement for golden welds, Its a general Practice and also you may refer Project specification as Client Issued ..You have have found some criteria

Dear All,

 

In pipe line activities the joints which are not hydro tested are generally referred as golden joints.

These joints will come especially making tie-in's of for 2 hydro test of sections.

I was experienced with the section as follows….

 

100 % NDT Is must in this case.

 

Option 1

1.      Root 100% DPT

2.      Every layer of weld with 100%DPT.

3.      Final run 100% DPT.

4.      100 % UT.

 

Option 2

1.      Root 100% DPT

2.      100 % RT

 

This is my personal experience

 

Thanks & Regards

Mr Gulam

 

I could remember the following things for Golden weld.

 

a) It means , other than of fabrication shop welding, the balance welding which will  be done with only one joint at site welding( or) in a tie -in work process. This type of joints are confirmed by 100% RT or UT (NDT), since there may be  a practice problem in the hydro test depends with the pipe  length.

 

b)There is no specific code for Golden joint but most of the companies are follow  to perform a "golden weld", with 100% NDT by eliminating hydro test.

 

c) We can refer  ASME 31.4, and  it  permits a "waiver" of a hydro test on "tie-in" welds between two sections of piping , that the weld has already undergone 100% NDT (see Section 437.1.4 (b) Testing Tie ins, ASME B31.4 2002 Edition).
