PV vertical, approx 2m dia, A516-70 steel, WT in this area just under 30mm, temp ambient. we are an engineering contractor so don't have the original design calculations which are OEM proprietary, the design calcs for this part in this area would be far too complicated to replicate as we have no...
Hi Ed,
the material loss that we have is that the part has not been fabricated to drawing - so manufacturing error. the fab shop is looking to try and salvage the part rather than scrapping and so are proposing to build up the lost material with SAW bead. this is an accepted repair for a lot...
Hi all,
thank you for your replies. r6155 to answer your questions its a vertical PV which is part of a hydropower scheme so temperatures are very stable and around 15deg mark on average. the medium is only water, and sometimes small debris, but with it being below the water turbine it can be...
Hi all,
this question concerns a vessel that is in a high vibration area as it is sat immediately below a francis runner in a power scheme.
The wall thickness of the vessel has been measured and is 2mm below the drawing tolerances so the suggestion has been that it could be built back up...
Thank you to everyone for your input - appreciated :)
@SWComposites @Hydtools, yes this is a fuse pin to prevent overload being transmitted into an expensive, safety critical, section of the machine. The shear dia will indeed be set based on the critical force at which the pin needs to undergo...
Hi all,
I have been searching, fruitlessly, for good practice guidelines when it comes to shear pin design and the ratios to set the pin OD and shear dia to. We deal a lot with retrofitting solutions, so unless I can persuade the client to bush this particular lug the OD of the pin is set...
