steel conduit help

[h901]

hi everyone

i've recently started using steel conduit and so far most of the jobs where i've used it have been fairly simple (straight runs). i've got a job that requires quite a few 90 bends to be made (i've bought a hilmor bender and have been practising using it) i've just got a few questions which i'm hoping the members with more experience than me can help with. any other tips and tricks will be very helpful too

1) should the saddles be installed first?

2) how would one connect conduit with a 90 bend to a straight piece, if for example the run is quite long - something like - I________I
is this done before or after fitting it to the wall, as i tried doing it once when it was already fitted to the wall and couldn't get the couplers to hold (before fitting to the saddles), as i was screwing one side on, the other side of the coupler was screwing off the other conduit

3) what are conduit nipples used for exactly?

4) when trying to make a 90 bend at around 1.5m in the conduit, i wasn't able to do it with the hilmor shorty as the conduit hit the floor before the bend reached the correct angle, so instead i cut off the top of the conduit and then re-attached it later with couplers (was this correct)

apologies for the long questions and thanks in advance

Can some tell what a 20mm nipple looks like

Don't forget it is critical to paint the exposed threads after making the running coupler.

Oh ok, is there any specific paint to use to keep the look consistent?

I've tried to understand what you meant but for some reason still don't fully understand. I appreciate your help though.

Could somebody possibly show me a picture of how a fitted running coupler looks (whenever you get a chance) thanks again

A "chapel hat-peg",is the answer to that question

A 20mm nipple is a coupler sized threaded piece of conduit, an example of the uses of a nipple would be to screw into an unused conduit box out let that you wished to add some extra conduit. 20mm Conduit Nipple - https://www.tlc-direct.co.uk/Products/CO20NIP.html

Or to use a runner on, through box etc.

Oh yeah Running couplers I do miss those beauties

A good electrician should never have to do a running coupler anyway
