Re: [MW:10540] Welder Qualification by UT

Dear Ramesh,
 
Find attached the file with description regarding the latest edition 2010 changes.
& also to qualify welders by UT in addition to the below points, a approved procedure for the same should be available.

Yes it is permitted from year 2010 edition (If you are asking for ASME BPV Sec IX).

Generally where the term "radiography" or its derivatives have been used in Section IX in the past, the phrase "or ultrasonic examination" has been added

or "volumetric NDE" is used. The acceptance criteria are similar to those for radiography. The big limit on using ultrasonic examination on performance qualification tests, however, is that the coupon or production weld must be ½ inch thick or thicker.

Forms QW-484A and QW-484B have been revised to add a check box choice of RT or UT when volumetric NDE is performed.

ِِAccording to ASME IX you have two options

1- By RT

2- By DT

No other option is permitted

Dear all experts,

 

Can we qualify welder by UT?


 

Thanks,

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, ...
