RE: [MW:22974] PQR without impact test

I understand that you are changing the welding consumables to obtain better toughness but want only to do the Charpy tests in the new WPQR. This has to be a waste of time and effort. Do a complete new welding procedure qualification, otherwise you will be arguing with your client for evermore.

yes u can use the same PQR.........while welding the monitor the parameters nd ensure it shud be with in the limits as mentioned in WPS.  AND SENT FOR iMPACT TEST,..

asme sEC- IX also permit this.

 

If ur client dont agree for that , u can go for all the best , it will earn trust & confidence of your client..moreover tensile and bend tests are not costly.

 

For your information and persuation.

 Dear expert ;

 

we have a WPS and PQR for A333 Gr 6 welded with ER 70S-3 and E7018 , the mechanical test in the PQR are only tensile test and bend test.

 

Our client didn't accept the PQR because is missing impact test and he ask to repeat all the PQR with all mechanical test ( with ER70 S-6 for better impact test result ).

 

it's possible to keep the PQR and to make only the impact test ( we can weld a 6" pipe according the WPS but with ER 70 S-6 and take specimens for impact test ). ????

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, ...
