Re: [MW:34331] Changing filler from er316l to er308

By Materials & Welding
Please check design temperature and fluid service, if impact test requirement you can not do. if impac test requirement you can do that.

Dear Experts

We have prepared SS PQR with 316 PIPE and ER316L filler

Right now we have project of SS304 to SS304 1 1/2"pipe welding for flocculant service.

As changing filler classification from PQR to WPS is supplementary variable as per ASME SEC IX.
 
Can I use my SS PQR 316 to prepare wps for ss304 to ss304 by changing only filler material to er308 (in pqr it is er316L) as both material falls in same P no and group no.

Can I strongly justify my point of changing filler classification er316L to er 308 in wps without undergoing any additional testing or procedures.

Kindly suggest the strong points with standards if any.

Thank you in advance

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, ...
