Re: [MW:13024] Subcontractor WPS

Hello,
 
Basically all welding qualification is for assuming responsibility of welding done by contractor.
 
In your case if Y is owner of the palnt and given complete EPC jobs to X, then it is up to X company to decide whether they will insist their subcontractor to qualify new WPS or may ask them to use their own WPS. Now if X has assumed all the responsibility of welding for the Y customer and Y do not have any problem as long as X assumes all responsibility then it works.
 
Now if X wants that their contractor should accept rersponsibility of welding done by them then X may ask his subcontractor to qualify new WPS.
If they insist them to use thier WPS it means he wants their subcontractor to supply welders only and wants to qualify using their existing WPS as reference documents.
 
Here in this case X (EPC Company) is reponsible for all welding done by them. Commercially they may hire their own welder or ask subcontractor to supply welders.
 
Hope this is clear to you.

Hi,
 
If a contractual item call for a specific WPS then you shall use it , other wise the contractual item should specify the aplicable standard for weldings and you shall use it and choose or qualify a WPS according to that standard.

Note: Generally the contractor write the WPS as a basic engineering deliverable.

Dear all, can anybody guide for following problem ?...................for example any EPC company has goven a contract for fabrication to a sub contractor....and that EPC company wants the contractor to follow their WPS only...and also they are forcing the contractor to conduct welder qualification tests only......my question is that can any contractor follow the WPS established by their client without further qualification from his side ?................

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, ...

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...
