I'm a little out of my element here and there is no-one on site to ask (i.e. no qualified person) -looking through info on API 650, API 2000 etc, what governs alterations to a tank, 9 metres high, 9 metres diamter that conatins a slurry ( non flammable. non toxic etc)? - there is a manhole for...
We regularly use Vic butterfly valves, but recently have had trouble with the larger sizes (10"Vic-300)-using them on compressed air lines- anybody use anything more robust
(10', 115 psi, steel pipe)-problem is after a short time finding them very hard to close
I was doing research into 'cooling' systems when I saw vortex tubes- although most of them are quite small, I was wondering if they have any applications for using them to cool a room? I have an abundance of compressed air-would rather not use standard air conditioners(as in a house)-
(drop in...
Not sure if this is the right forum- we use 12VDC strobe lights on vehicles , but also have electric detonators in use- someone heard throught the grapevine that the capacitors in strobe lights could cause detonation of blasting caps? I guess same theory as radio tramsmitters on construction...
We recently completed our annual oil analysis on seven transformers- 4 of them showed a significant rise in dissolved gases from last years results. We were somehat baffled because we've never seen a sudden increase like this. Someone then mentioned that several months ago the utility increased...
Does anyone know of a source for 4160v, dry capacitors?
We wanted to install capacitors but manufacturer only has oil filled ( these will be us in an underground mine). We could use the oil filled but need to enclose in a vault but there is not enough room in the intended location.(have tried a...
We are investigating using cone sumps ( rather than trditional cleanwater/dirty water decant sumps)- the plan is to divert the water to the top of the cone, and clear water decants off to the clean water sump- the 'fines' will settle to the bottom of the cone & will be drawn off into'slime cars'...
We're in the process of planning a new loading station ( conveyor loading transfer car ,measuring bins then into skips)- the current layout had two conveyors because of the orientation of the existing ore/waste passes- to eliminate one belt we asked engineering to look at the layout again- now...
I posted this in another forum but maybe you guys can help- I 've been asked to find a way to monitor temperatures on brake linings- I see there's been work done on tractor/trailer brake/wheel systems but are there commercial systems out there ?- my application is somewhat different- the system...
Does anyone know of any refernces for monitoring brake lining temperature on hoists? We've been asked to provide constant monitoring since the hoists run from a remote location- we had one instance where a small piece of brake lining became wedged between lining & brake path- created a small...
Just looking for general comments on a problem we are having with aluminum cast fan blades. Without getting into a lot of fan details, we've had 4 recent failures ( catastrophic) of the blades. Visual inspection of the blades looks like there are large cavities or pockets in the casting (...
Wondering how other places handle human waste? port-a-potties? RBC's ? We are a combination track/trackless- have a honeywagon for track areas but it can't go to trackless areas- suggestions are honeywagon for forklift orscoop forks? composting toilets?
We are undergoing an expansion at our plant - we were discussing the requirements for backing up PLC's (4) with UPS's - our IT guys want to use one large one, other people would prefer a separate one for each PLC - another suggestion if we went to one large one was a UPS backing up a UPS but...
Just looking for thoughts on using a 'control choke' as a pressure reducing valve- max pressure expected to be 475 psi
in and 90 psi out- clean water ( not oil or gas)- the usual PRV's have been a problem & these look to be more robust, although I haven't seen any applications outside the oil &...
First time I've ever asked for help here- imagine a 'cave' that holds 60,000 gals of dirty water. Cave is divided in two - a 50,000 gal side and 10,000gal side- by a 'weir' extending almost to the ceiling.The fine particles in the water are supposed to settle on the large side and the 11 stage...
