Pipe Taps

[Chillylulu]

In a past life i did a lot of steel pipework manifolds that were manufactured to fit then Galvanised. All threaded outlets on the manifolds had to have the threads re-cut to remove the Zinc build up from the galvanising process. Hence the collection of BSP taps 1/8" to 2". The threads were easier to clean out if they were heated gently before the tap was run in & out of the fitting several times.

Nothing 6heeds like 6hest, right?

If you're responding to mine, I was attempting a pun on "nothing succeeds like success."

I'm thinking Chilly had his fingers on the wrong part of the keyboard and didn't realize it before posting.  But, you know, ya can't just leave something like that sitting there; gotta do something.

Don't take offense at our fun, Chilly ! We know about your troubles with your hands and fingers.

Where's Aunt Phil with "I Hate puns"?? :-)

Ugh. Nothing worse than mistakenly trying to crank an NPT fitting into a BSP threaded hole. For each diameter, the thread pitch differs by only one or one-half tpi. By the time you realize something is wrong, everything is bound up tight. And leaking like a sieve.

I know , nothing like an ABC when you meant to have a 123

I've no idea what that says.

I would say that we would heat up the galvanizing and wire brush it out or off. We would use old wire brushes for cleaning copper fittings. Cut them off and put them in a drill. Cleans the galvanizing right off to the metal.

I once got a piece of pipe back that had been hot dipped. It was an 8" × 12' or so long piece.  It had been fabbed with a flange on one end,  but the shop had threaded the flange on instead of welding one on. The galvanizing melted all the teflon pipe dope off the threads.  All pipe threads have a little helix shaped tunnel at the top of the male thread and the bottom of the female thread.  Pipe dope fills thst spot.

It wouldn't hold water. I spent a couple of hours with a 1/4" cold chisel and some lead wool packing that thread. It held the 200 psi test.
