Re: [MW:34138] CLAD MATERIALS -WELDING WPS /PQR ERNiCrMo3 / 7018-1 Combination

By Materials & Welding
Hi everyone
For joining the C.S pipe that cladded with Inconel 625, it should be fully welded by NiCrMo-3 (SMAW or GTAW). welding the root pass with NiCrMo-3 and filling the join with 7018 or other C.S consumable material is big mistake. because during welding we'll have dilution and We'll have Cr3C2, this composition will be deposited in the grain boundary and make the alloy very brittle.
If weld a test coupon with ER-NiCrMo-3 and E7018 you can see how easily it will be broken during the bending test.
I have more experience in welding the claldded pipe together and overlaying the pipe so feel free to contact me for more information.

Hi experts,

 

CLAD MATERIALS -WELDING

 

We have the following Clad Pipe and we are preparing WPS /PQR to weld this SPOOL.

As I know we need to use ERNiCrMo3 / 7018-1 Combination (if GTAW+SMAW) to Complete weld.

But if anyone is having experience with this, please advise whether we will go with

 

GTAW - ER NiCrMo3 ( Root & Hot )

 

SMAW – E7018-1 (Balance Filling /Capping).

 

Please Explain any troubles may have happened regarding dilution or not.

 

Need Aramco and International code reference? If any one has a sample WPS/PQR Please share with us.

 

Any corrosion test or NDT

 

Waiting for your scientific and specific reply.

 

Thanks in Advance.

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, ...

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...
