Re: [MW:14081] Impact test report of PTC

By Materials & Welding
SA333-6 is a LTCS and must use a filler metal with Ni content eg. ER-80S-Ni2.

Dear Shadab, salam
 
We have welded PTC with qualified wps with E70S2 @ minus 48deg C,
 
Test was carried out for weld,

Dear Ali,
The consumable for tig Filler metal ER70S2 is not suitable for impact test @-48 degrees.
Also want to know the heat input and location of charpy impact test.

Regards
Shadab

Low temp vessel PTC for head to shell c-seam; Head : Cap SA420WPL6, Pipe: SA333 Gr 6; Filler metal ER70S2+ E7018-1; GTAW+ SMAW process.
 
PTC used as filler metal is not SFA classified for low temp -48deg C
 
Impact test results: 18, 14, 12 Joules test piece size 10 x 7.5 x 55 @ -48deg C;
 
Average value required for 10x 7,5x55 is 15joule; single specimen 2/3 x 15: 10joule
 
Reference ASME SEC VIII Div-1 2011a UG 84 & UCS 67
 
Dear Expert,
Let me have your advice whether these results are acceptable.
 
Thanks
Aly

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, ...
