Re: [MW:34199] Impact Testing requirements for PQR

By Materials & Welding
Dear all

Is it mandatory to do Impact Testing in PQR our clients doesn't approaching to us to do Impact Testing they only required impact Testing in Forging Material Tee and flanges.

That's why we are doing Impact Testing in PQR.

Thanks & Regards
Jack

in addition to above one may consider PWHT requirements if anything applicable as per the design and client spec, if PWHT applicable one may consider additional PQR's or based on the construction code exemption recommendations PQR's Can be avoided by following pre-heat requirements of the construction code.

Appreciate efforts and initiative from ENG.Ahmed.

Just to share. 2 PQR's 6mm & 23mm is sufficient.

There is an ASME Interpretation stating PQR qualified on 6mm and higher thickness qualifies in the range from 16mm.  Someone please share the Interpretation.

Thanks & Regards

3 PQR's may be sufficient , 6mm (3-12) 10mm (10-20) 23mm (16-46)

Dear all,

In Our project has 3 inch to 24 inch and it's thickness 5.49mm to 45.24mm and Impact Testing required for above thickness.
Please clarify how many PQR are required for this job 
Please consider the Impact Testing also mentioned each PQR thickness qualify 

Regards
JJ

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, ...
