[MW:954] CC2235 UT in lieu of RT

By Materials & Welding
Dear Raghuram,

Generally we give marking as RT-1 only with a note in Manufacturer's
data book (MDR) that UT for so and so seams was carried out in lieu of
RT.

Dear Raghavendra
Since you are using CC2235, I have a doubt on Name plate marking as per
UG116 for div 1 vessels. In case when a portion of the vessel RT**ed as
per UW11(a) and the remaining portion UT*ed per CC 2235 in lieu of RT,
what will be the marking, is it RT-1?

Dear Rohit and Raghuram,
Thanks for the information related to Codes,standards and
Specifications.
Our Organisation has obtained 'N' Stamp from ASME during last year and
once the nuclear treaty is signed between India and USA, we have got
bright chances to get orders for manufacture of Nuclear power related
Equipments from abroad.
As we could successfully replace RT by UT as per CC2235 incase of
Sec.VIII vessels, I want the same trend to continue in case of Sec.III
of ASME as well, which are expected in future. But all nuclear new
construction codes of ASME are strong believers in Radiography. I am
looking for a hint to extend TOFD on nuclear new construction also.
That is why my query related to the same.
Hope I could convey.
regards,
Raghavendra

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, ...
