Re: [MW:35966] WPS requalification for repair weld ASME B31.3

By Materials & Welding
Greetings,
Thank you for your kind response.
In pur PQR, soaking time for repairs Welding not considered.

See snap shot below from ASME B31.3. No Repair procedure is required. But PWHT has to be performed after Repair. PWHT soaking time should have been added during the original PQR Qualification or Simulated test coupon including Repair soak time shall be included during Material testing.

Greetings,
Need expert opinion for the following query:
Construction Code ASME B31.3, Qualification ASME BPV Sec. IX.
One of the WPS is qualified for Low temperature Carbon steel with impact testing and PWHT. The qualification range is 20mm to 36mm. 
PWHT is applicable (Project specification). Soaking time was 1 hr 30 minutes.
Question: Is this WPS qualified for a repair weld with this soaking time? 
Is a new PQR to qualify the repair joint?

Best Regards,

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

By Materials & Welding
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

By Materials & Welding
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, ...
