The New “What did you do with your Z today” (with off topic replies) XXXIV

Rusty

7/8 fine thread roughly gets torqued from 501 to 668 ft lbs depending on grade. Biggest torque wrenches are about 600 ftlbs. So you use a torque multiplier for anything over 600 ftlbs.

Choose your multiplier.

I think the lug nuts on my motorhome get torqued to 600 ftlbs. That's what the shop said when i got new tires on it last year.

They’re over torquing them, newest specs on the M22x1.5 studs w/the nuts that have swivvlers washers behind them are a couple drops of 30wt. oil on threads & on nut@washer - then torque to 500#
Older books say 450-550, some said 450-500
I still use my 1” Ingersoll Rand, fed by a small 1/2” line w/120 psi & do my thing.....just been doing it too long

We had a few big nuts and bolts on the oil pumps we machined.

Rusty

Let me know when you start playing around with 6" and bigger diameter bolts, nuts, and studs. Where you measure torque in the stretch of the stud. Measure the length. Heat it up. Measure again. Keep heating unit you get the length you want. Then screw the nut down.

Another one was to use a stud heater to heat the stud up after you had screwed the nut down tight. Then once the stud grew in length from the heat. You turned the nut down again. Counting the number of flats on the nut you turned. If you couldn't turn the number of flats needed. You kept heating the stud up until you could.

It's always fun when the nuts and bolts weight more than you do.

What was the driver for that pump?

Steam turbine, gas turbine, electric motor. Either direct drive, or through a reduction gear box. I've played with this stuff more than once.

Also, change a few things and it could be a compressor.

I deal in offshore O&G. I know all about large pumps. Just curious what the driver was for this pump.

I am woefully ignorant of that as those was manufactured, I believe in Australia.
I did find a picture for you though.

Disappointing.. I had a wonderful vision of a BFTW, one that God would use to tighten an axis nut for the Earth.
