Re: [MW:35706] Qualification of Square Tube As per ASME Section IX Edn 2023

By Materials & Welding
In my opinion square tube / pipe shall be considered as plate welding which involves overhead, vertical and flat welding. Procedures qualifying above 
Positions and required thickness may be used for welding. In pipe welding direction for welding is continuously changing and requires more skill hence diameter limits are given in code.

Dear Members,
I require Qualification of Square Tube as per ASME section IX.
for Butt Joint Can we Consider Square Pipe as Round Pipe or tube for Diameter Limits as per ASME section IX 
 
for T joint in Square Tube to Plate, Can we use Square Tube  instead of round pipe for procedure Qualification as shown in figure.QW 462.4(d) ASME Section IX 

If yes,Please mention Reference & Thk ,Diameter Limits for same.

Thanks

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, ...
