Hello All;
A pressure vessel was constructed with SA 516 Gr.70 has undergone PWHT initially in 1975.
How many times the vessel could undergo repair & PWHT in its lifetime? Are there any maximum times can anyone do PWHT?
Will metallurgical changes occur during subsequent PWHT?
Where I can find...
Hello All;
We had an average size of repair completed on an internal attachment to shell of a pressure vessel. The defect area was ground smoothly and filled with proper weld procedure.
Subsequently, the area was examined by 100% MPI. No defects were found. Hydro test was not done due to...
Hello everyone,
Vertical plates which supports downwards trend of the flow in digester (pulp and paper making) has been bulged. Those bulges are quite large. The plates made of 304L SS. The temperature in this area falls between 300 - 320 F. Can anyone tell me what was cause for bulging to...
Hello everyone,
I need to weld channels which hold the plate as shown in the picture to the Chiller support. The welding method is SMAW using 7018 rod. My concern, will there any damage to the CuNi 90/10 cooling tubes adjacent to welding of these channels?
Appreciate for early response.

Hello All,
I need to calculate output current of Mg anode which protects the pipeline.
I know the area of the anode. Where can I find current density for Mg (magnesium) to soil? (we know the soil resistivity)
Thanks for your help
To All;
Does anyone knows reasonable interval between calibrations of a torque wrench in a construction site? Some company specifications call for calibration twice a day which is impossible.
Thanks in advance
