Re: [MW:34905] Thickness range in WPS for Fillet

By Materials & Welding
Please refer ASME SEC. VIII Div. 1, Table UCS -56-1, PWHT requirements for CS & Alloy steel ( P- No. 1)
 General notes : (b) 1 & 2.

Dear Mr.Sudalai,

Thanks for your response at the right time.

if possible can you please point out in the ASME section where this point is mentioned. So it will be very helpful for me to share this knowledge with my reportees and team. 

Regards,

Dear Mr. Shivasankar,

The fillet weld size should be less than 38mm for the WPS which is qualified without PWHT or less than 38mm thickness. Otherwise, the WPS should be qualified with PWHT.

As per ASME SEC. VIII Div.1, PWHT is mandatory above 38mm Thickness.

With Thanks,
Sudalai. M

Dear team,

can anyone clarify my issue.

During the preparation of WPS & PQR of SA 516 GR 70 to SA 516 GR 70 - 10mm Plate Groove weld, my AI (Authorised Inspector) was insisted me to put the Thickness range for fillet weld as 38mm maximum in both WPS & PQR. 

I am unable to understand this. Because as per ASME Section IX Table QW451.4 - All groove weld tests can qualify "All fillet sizes on all base metal thicknesses and all diameters" So according to my understanding it should be unlimited but why my AI insisting me to put as 38 mm max..

Pls Clarify.

Regards,
Shivasankar A

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, ...
