New from Old / Re: Resurrection of a CFEI 100 KVA Induction Furnace
« Last post by awemawson on Today at 06:56:54 AM »Glad to say UPS delivered my B.E.S. plumbing order nice and early so I was able to get on with putting it all back together.
A bit of heat released the Loctite holding the 1" BSP elbow to the various other fittings and having replaced the elbow with a Tee, the ballcock with one without a burst bit, and installed the 1/4" BSP air ball cock and PCL fitting I was able to put it all back on the wall. I took great care to mark the blue MDPE pipes for insertion depth and seat them firmly as both have to go on as an assembly - if I've got it right it wont leak . . time only will tell !
Then I removed the old nylon reinforced umbilical pipes that take the feed from the borehole to the heat exchanger, and the return that goes eventually to the stream via our land drains. I had bought some much more substantial stainless steel wire reinforced rubber 'Neptune' hose quite a long time ago as the nylon was a temporary solution - it had worked OK but wouldn't take kindly to a splash of molten metal. So now was the time to uses it.
All went well and I'm now waiting a few hours for the Loctite 542 to cure before I pressurise and test it.
The split / self fixing 1/2" wall insulation for these pipes has also arrived but the trace heating cable hasn't so I can't wrap up the umbilicals just yet. It's going to be great fun installing the trace heating. I've ordered a single 14 metre length the mains 'start of which will begin at the wall panel, wrap in a spiral round the return pipe, enter the chassis of the chiller wrapping round its internal pipes and exit wrapping around the flow pipe ending back at the panel. Or that's the theory - I can imagine quite a tangle during the wrapping !
