Bending 20mm Round Electrical Conduit
wrote in message

I've seen installations where this type of conduit has been bent at
90
degree's and at various angles.
My question is how is this done ? Do you have to gently warm the
conduit to do this ? Must the conduit be supported on the inside so
that it doesn't collapse ?
It must be possible but I need to know how ?
TIA

A conventional pipe bender can be used on black metal or galvanised
conduit - (you need the correct sized former though). Plastic conduit
comes in two 'weights' thick and thin walled. The thick walled variety
can be bent with a pipe bender, but the thin walled variety needs an
internal spring. With either weight of plastic conduit you get far
more 'spring back' than with metal conduit, and it varies quite a bit
from make to make, so you have to 'bend further' than you would for
metal. Be aware that the thin walled type will often show the spring
pattern on the outside after bending.
