Re: [MW:19367] Re: API 650 RT repair %

By Materials & Welding
Dear,
You are lucky that this % is based on length and not joints.
General repair % action criteria is this: 
< 1% Tolerable
Up to 1.5% Caution level
1.5 -2.5% Welder needs to be warned
>2.5% Welder to be withdrawn from job and sent for practice
 
With Best Regards,
Shashank C Vagal

Sunil,

No need to worry abour porosity or TI..length of repair how much they excavate for repair.is it clear

take welder wise length of welder welded divided by length of repair of that welder.

Length wise repair is best way to avoid confusion between plates and pipe welding by welders.

Rejection rate/repair allowed is defiantly mentioned in your project spec.


regards,
mohd.

Dear All,

Kindly share infos about the weld repair percenatge / rejection rate
with respect to API 650 tank construction. sub-con is calculating on
the basis of repair length divided by total weld length. but the
repairs amy be porosity, tungsten inclusion or other rounded
indications as the case may be. in such cases how we could calculate
the length exactly. also please share why it is not possible by
individual welders too (or how their % can be calculated). i beleive
it is not mentioned by 650.
Thanks in advance,
Kumar

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
