[MW:25784] RE: 25779] Limits of E6013 in pressure vessel (sec viii div 1)

Hi,

It is either 6013 or 7018 - whatever it may be, you have to establish a WPS and then qualify the PQR -

If all the particulars (mechanical, chemical and etc.) are complying to the specifications and to client requirements in the established PQR - then there will not be any issue of using any consumable.

Or...

If your client specification has called for any specific requirement of the electrode (say E 7018) then u have to qualify the PQR with that only.

Or...

If you have any constrain in using any electrode (practical problem, approach, easiness in welding, weld metal deposition rates, any power source limitations, any specific NDT requirement and many more particulars) then also, you may opt for 7018 or any other grade to suit requirement -

But in and overall - you have to qualify the PQR with all the variables...

Hope u understand...

Thanks & Regards,
Lakshman Kumar B,
Project Manager.

Dear sir,

In fabrication of pressure vessel from 10mm thk plate, would we allow to use E6013 electrode.

Is any where given in code of sec viii div 1, about limits of E6013, or only E7018 is allow.

Regards
Prasad Rode

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, ...
