RE: [MW:7939] golden weld joint require ments

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).

Dear all,

can any one explain the golden joint welding , NDT and inspection requirement with Code references.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change. Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
