Good Afternoon,
During a dye penetrant examination of Static package steam turbine blades, we found out several indications on blades foil.
Indications are rounded with several diameters 4 mm-16 mm and one is located on the weld toe (16 mm). I've being looking for a std to evaluate the severity...

Good morning everyone, perhaps someone may help to clarify a point
I´ve being inspecting some storage tanks welds, During our last inspection we found 2 mm undercut depth on the external surface of shell just besides the external fillet weld on the shell to bottom joint.
If you go on to API 650...
Good Morning,
Perhaps someone can be of assistance. I am qualifying a procedure to Butt weld steel which is under the specification API 5CT Grade K55. This is normally used in drilling and we use it in geothermal application for vapor under 300 psi and 180 C.
I´m trying to find an API RP or API...
Well not really, What we normally were doing is based our judgement on design conditions.
We were using formulas and the parameters of the plate to calculate minimum wall thickess.
One of the boilers actually is 0.250" inches thick for the wall tubes, we found very rare that only 0.017" were...
Good Morning Everyone, Perhaps somebody can be of assistance with the following issues
We have a situation with a power boiler evaluation, design conditions on plate are 72 kg/cm2 and 483 C.
Furnace tubes are 3" OD.
We would like to calculate the minimum required thickness per ASME CODE SEC 1...
Well You may see the attached picture, thereis actually a staright line in the center but there are no sign of depressions unless they are very fine and due to film sensitivity it can be shown on the radiograph.
Will do the micro as well as the X rays inspection when removing the reinforcement...
Thanks guys,
Actually we do the Dye check using fluorscent and it was ok, even we use a 20X magnifying and there were no indications.
Ed, are you aware if there is any available and approved reference to support your point? We actually deal with auditors and people that are not familiarized with...
Actually is X rays, we shot it with 70 kV 1.4 min using a D4 film. The film is very defined. We increase the kV and actually adjust the time and the indication still appears
This might be unsual and I will appreciate any opinion
We were qualifying a mmanual GTAW WPS to weld stainless steel sheet metal 0.040" thick. We use about 40 A and a travel speed range between 2-4 in/min. Gas flow used was about 20 CFH and we use also backing gas. Electrode used was 0.035"...
Hi Everyone,
Perhaps somebody can be of assistance. I'm evaluating if a WPS can be used for a specific procedure. In our country we normally use AWS and ASME, I have no Equivalencies for S700MC to an ASTM or AISI, I found on a web site that it might be equivalent to A514 but it doesn't match in...
Hi Everyone,
I will appreciate a lot if someone can provide an idea about how shoul I proceed in this case.
I have a customer that request to perform the evaluation of some pressure vessel for vapor service.
Neither his organization nor me were able to find documentation about the vessel such...
Hi everyone, perhaps somebody may be of assistance, I was inspecting a Ti weld Ti 6 AL 4V, I´m concern due that after repair it was cracked within the weld, it was repair and after another inspection it continues to crack and so on..I´m aware that some codes or spec. does not allow to repair...
I'd like to thanks all of you for this valuable information, we will proceed with hardness and UT, PT for the edges to ensure good quality, and also we wil get AWS D14.6 seems to have additional requirements.
Thanks again for your assistance
Hi everyone
I'd like to know your opinion for the following case:
I'm quite familiar with the elaboration of documents such as WPS or PQR and WPQR when using for example ASME code SEC IX or AWS D1.1 concerning pressure vessel or steel structure erection. I have a collegue that consult me what...
