Re: [MW:33545] Production Test Plate

By Materials & Welding
Dear Sir,

Our case is SA 516 Gr.70, 70 mm thickness, and the welding process is SMAW + SAW.
I believe 300 mm (w)  x 500 mm (L) dimension is enough. - Pls confirm

Thank You & Regards

Just for clarity.

Below mail on calculation gives you the Length of the Test coupon.

Width of the test coupon depends on thickness & welding process


Thanks & Regards

for thickness less than 10mm -300x350mm 
  thickness more than 10mm-300x400mm
PTC should be as per each wps used as per each seam.
if wps same for cat A and Cat B -1 ptc require
if wps use for dish head is same as cat A and B no ptc require extra
if wps use for dish head is diff as cat A and B  ptc require separate
refer below attach pic also

Dear Gerald Sir,
Greetings!!

Please advise the dimensions of the test plate.
300 mm (W) x 500 mm (L) is enough.

In our case one test plate is required for each welding procedure used for Cat. A & B Joints. 
80 mm thick dish heads are manufactured with a single joint - PTC is required for these joints.

That's why we subjected it to the impact test.
What I want to learn is how many samples should be taken from where in the sourced material I want to specify below?

I will be glad, if you inform me.

When Impact testing is a design requirement as per ASME Sec.VIII Div.I, production Impact testing is required. Only Impact test is the requirement as per ASME Sec.VIII Div.I unless other tests are required by your Client Requirement.


For production Impact test follow below section.

For any specific requirement as per below table, please describe in detail what clarification you require.

We design a pressure vessel according to ASME VIII Div.1 and our customer request shows "Production test plates according to Code requirements". Can you tell us the section showing where we can take samples from materials that vary according to their thickness. Or I need someone to contact me about the issue.

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, ...
