Re: [MW:17517] WPS for A350 LF/2 forged flange

Dear rajagopal sir,

A350 LF/2  has group n0. 2 &  API 5l x42 has group n0.1.
for weldig of LTCS consumable should be impact tested with acceptable UTS and YS.and impact testing requirement group no. supplementary essential variable.
you can tell in your opinion in welding Of A350 LF/2 & API 5l x42

Thanks & regards,

Dear Hemal,
Can you say why?
What is stopping you welding the LTCS material with X 42?
Thanks and Best Regards,
K.Rajagopal

Dear raghuramji,

                  we cant weld A350 LF/2  material with API 5l x42 by using E-7018-1 only.you cant weld LTCS material with E-7018 and you cant use E-7018-1 in place of E-7018 as per
 QW-404.12(e)

Ezat Adel question is to use LF2 in place of A105 for normal use (not for low temp). why you would like to suggest low temp consumables?

Dear raghuramji,

      A350 LF/2 is LTCS material and WPS you have is CS to CS(A 105 N to API 5l x42) with full SLAW process (E-6010+E-7018),and if you want to weld CS to LTCS (A350 LF/2 to API 5l x42) it will be dissimilar metals,and if you want to  use full SMAW process then you should have  to compulsorily  go for E-7018-1 and ER80Sni-1 for full  GTAW.In both cases electrodes/fillerwire should be impact tested before use.and also  A350 LF/2 to API 5l x42 both has different group no,in both  SMAW and GTAW  processs group no. supplimentary essential variable.so you cant weld that both metals by your WPS CS to CS(A 105 N to API 5l x42).you should have to establish new WPS.

Dear Expert ,

Could you give me your opinion about my supplier send me A350 LF/2 forged flange instead of A 105 N forged flange and i have a WPS for welding A 105 N to API 5l x42 in your opinion this wps will covered  A350 LF/2 to API 5l x42 ?

as i know  A350 LF/2 is a low temp.carbon steel and A 105 N is a carbon steel and both material has the same P no.,Group no. and in my activities i do not need to use a low temp. CS but my question  if i accept this flanges  the wps i have will covered the case.

the WPS i have is E6010 for root pass and E7018 for filling and cap

Thanks in advance

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

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

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, ...
