I have just had an Eddy Current Inspection Carried out on some structural welds in a crane pedestal. There was 10.0mm crack reported in 2002 (before my time with the company) this was never verified with MPI and the NDT tech did not mark the location. During the subsequent years no one was...
The company I work for has had a refridgeration skid designed & buit by a vendor. The condenser design seems a bit unusual to me. The tubes are designed to 15barg pressure and the shell side is designed to 30barg. The wall thickness of the tubes appears to be within the stress limits. But...
I have a 12" dia 10.0mm WT gas line operating at 10barg, there is a Thread-o-let branch connection to a bleed valve, the branch is 1" SCH 80 and has been found to have severe external corrosion damage, Radiography has calculated the remaining WT to be approximately 1.5 to 2.0mm from the thread...
I have a pressure vessel that has corrosion damage on the sealing face. The flange face damage is not severe enough to warrant a replavement flange, we are planning on welding ou the corrosion damage and machining the face,
The fabrication company have provided a weld procedure for V butt...

I have a 30 year old pressure vessel constructed from BS-150-151-28A plate. The vessel is in good condition and is still at nominal wall thickness of 19.0mm.
During an operational upset the vessel was subjected to a temperature of -14 degrees C, it was only at this temperature for 10 minutes...
I have a carbon steel 75.0mm thick pressure vessel with a 3.0mm 904L overlay. Internal inspection has revealed a pit defect in the overlay with a diameter of 5.0mm and a maximum depth (taking account of measurement uncertainties) of 2.5mm.
The vessel was heat treated during construction.
I...
We have a leak on a Riser line that is held inside a J-Tube on one of our installations (pipe in pipe). The internal pipe is the one that has leaked.
The question is would long range Ultrasonics be capable of picking up a pin hole leak, ie 3mm diameter hole being the worst case. The defect...
I have a Shell & Tube Heat Exchanger that we have just found pitting corrosion in the tubes during an IRIS inspection.
What I am looking for help on is where can I find information on the tube minimum WT for pressure retention calculations that I should apply in this situation.
For information...
I have a Carbon steel vessel that has a Inconel 625 overlay. The Ultrasonic operator has reported wall loss in the vessel and the remaining thickness is that of the carbon steel section and my thinking is that there is an area of disbonding and that this should be easily determined by a good UT...
I have a closed drains system on my platform that is fully welded from start to finnish of diameters varying from 2" up to 10" diameter. There is approximately 5 miles of pipework in the system. It has multiple elbows and branches and has been in service for 23 years.
I know that...
Does anybody know of an effective technique for in service inspection of Globe Control Valves.
I have a problem with solids erosion on the outlet side of the valves that I need to keep an eye on whislt remaining on-stream. Radiography is effective on diameters up to and including 3", UT...
