Re: [MW:25443] 6GR Procedure Qualification - Does it cover CJP Butt Joints during production

Re: [MW:25443] 6GR Procedure Qualification - Does it cover CJP Butt Joints during production - WPS and NOT WELDER

Hi, Shashank,

Thanks for your feed back.

Do you mind sharing the code reference that permits me to do it.

I am just referring to Table 4.1 AWS D1.1 2010 Ed. note d, which takes me to 3.12 and 3.13 and then again to 4.10, 4.13.1 and 4.13.2 and 4.13.4

Appreciate your thoughts on this,

regards

rudolf

Dear folks,
I have a procedure which was qualified, tested and accepted as follows.

1. Position of Test - 6GR
2. Pipe Used 6" Sch 120 and XXS
3. Process - FCAW
4. CJP as per sketch 4.25 CJP without any backing or backgouging.


Query.

Assuming that the welder is qualified, all other things are within control, thickness, etc etc,

1. Can I weld a Plate to Plate in CJP Butt Joint which does not have access to back gouging or back welding.

2. Can I have either a Single V or Single Bevel

3. Can I use ceramic backing


Appreciate your advise,

Regards
Rudolf

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, ...
