Re: [MW:8521] 2"pipe repair..... Partial

By Materials & Welding
Follow the following steps:
 
There is nothing wrong with partial RT or partial welding repair, it is well established practice in fabrication industry.
 
1. Mark the defect area as per the RT tracing
2. Remove the defective weld with the help of grinding (Groove shall be in boat shape to fecilitate the proper welding)
3. Carry out PT of the groove and RT in groove condition to ensure that defect is completely removed
4. Clean the groove properly to remove the PT residues (otherwise it will cause further defect in subsequent welding)
6. Carry out weld fill-up with the qualified procedure and WPS.
7. Carry out the PT and RT as final NDE.

Dear All,

   Here I have a doubt regarding 2"pipe welding . While  work with 2" pipe, if repair comes and founded in Rt. What we have to do as per ASME SEC VIII Div.1. I found one company is doing partial repair and taking Partial RT. Whether it is correct? I couldn't conclude with this. Please suggest a good answer.

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...
