Re: [MW:26053] 100 % NDE when No possible to perform pressure test

By Materials & Welding
Sir

Please refer ASME B 31.3 below:


345.9 Alternative Leak Test
The following procedures and leak test method may be
used only under the conditions stated in para. 345.1(c).
345.9.1 Examination of Welds. Welds, including
those used in the manufacture of welded pipe and fittings,
that have not been subjected to hydrostatic or
pneumatic leak tests in accordance with this Code, shall
be examined as follows:
(a) Circumferential, longitudinal, and spiral (helical
seam) groove welds shall be 100% radiographed in
accordance with para. 344.5 or 100% ultrasonically
examined in accordance with para. 344.6.
(b) All welds, including structural attachment welds,
not covered in (a) above, shall be examined using the
liquid penetrant method (para. 344.4) or, for magnetic
materials, the magnetic particle method (para. 344.3).

Thanks & Regards

which send you back to 345.8, which includes pressure test at lower pressures, but pressure test anyway

Subject: [MW:26005] 100 % NDE when No possible to perform pressure test

Dear Expert,

  Where we can find that Full NDE Volumic & Surfasic NDE for welded joints when is not possible to perform Pressure Test.

Construction code ASME B31.1

Thank you very much.

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, ...
