Pls explain in brief about Acceptance criteria comparison for RT,UT, PT (Casting/ Forging) as per ASME, EN,ASTM standards?

There is specifically requirments of NDT method RT for all weld joint ( i.e for all class of joint ).   We never used RT in normal practice for all project. Now for convince to client We required comparision sheet between RT & UT to justifying UT is better than RT.   Request to send Comparision of RT & UT. Please send comparision & revert back soon. We have to submitt QAP urgentely.     Regards,   Vikas Rana   -- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Dear,   Depend on your description, I can't tell which degree of corrosion in your plant, but I try to give you some advices.   First, try to find the root cause about corrosion, such as, whether it is materials selection issue, or the plant locate in coast, or not good insulation work, etc.   Second, according to accurate root cause, plant decide to do painting. Then, you should find the qualify supplier of painting, also, selection proper coating and  construction process is based on process service condition. So, clarify meeting of cross-displinary is necessary! Good luck!   Leon -- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Hello Dear, I think so you need to have HVOF high velocity oxygen fuel coating on those equipment's. It will be expensive but surely it can resist wear & tear done by sand. You can check more details. This is modern technique of painting may be the best one also.

Please give your advices on the following:- Best surface preparation where sand plasting can not be done. Best painting to be used in high humid areas and where surface preparation can not be done by sand plasting? After repairs and painting, rusting will take place within one year. Your input will be highly helpful.

For a short term exposure the specified temperature will not cause creep except overheating. In general the covection section tubes are designed for no flow condition for certain hours. Since your are measuring the skin temperature the tube inner wall temperature will be less than skin temperature. regards, Gopalsankar On 2014-09-30 07:45, pgoswami wrote: > Hi Jignesh and Dr Dilintas, > > A short note on this scenario, from Utility Operators point of view. > C.S will be pushed well above the upper limit and cause overheating of > SA 106 GrB.

  Nearest available electrode could be monel type with 70 Cu - 30 Ni. GMAW followed by SMAW is suitable GTAW. ECuNi- Coated Electrode Copper-nickel alloys and selected bronzes to themselves and to Alloy 400 or Alloy 200 Electrodes of the Copper-nickel classification are used for shielded metal arc welding or wrought or cast 70/30, 80/20 and 90/10 copper-nickel alloys to themselves or to each other. They also are used for welding the clad side of copper-nickel clad steel. Preheating is generally not necessary.   ERCuNi - Filler wire. Copper-nickel alloys and selected bronzes to themselves and to Alloy 400 or Alloy 200. In Copper-nickel filler metals, the nickel addition strengthens the weld metal and improves the corrosion resistance, particularly against salt water. The weld metal has good hot and cold ductility. Copper-nickel filler metals are used for welding most copper-nickel alloys. When using the...

No problem. You can grind portion where you get your hardness test . If you want to grind all around or removing the reinforcement, control the heat produce by grinding. Next time, do it before pwht.
