water line layout

[jtb503]

I feel dumb asking this, but i am having such a hard time picturing and drafting this. I am trying to layout a waterline, and rather than a 45 degree bend, it is typical to use two 22 degree bends. Does anyone have an example of this drawn so i can see it? Every time i draw it, it looks wrong to me.

It is not uncommon to use two 22.5 deg bends in a water line layout. Unfortunately I cannot provide you with a drawing of this. Are you doing this as a single line or double line drawing?

[jtb503]

single line drawing currently, but i will be showing double line in the future.

The one or two times I've actually seen it done in the field was NOT as a substitution for a single 45 deg bend. It was to make an offset.

Well, remember you do not have to use 22.5 bends, the water can be bent. When using D.I. or Blue Brut, you would stick the pipe straight in and then pull the pipe a little, not pitching the o-ring. So in sweeping turns no bends are needed. Just don't draw the water line as a curve, we always laugh at the engineers who draw a curve for d.i. water line.

There is less force with 22.5 bends... but with a 45 its not bad, ive used 2-45's instead of a 90 but not 22.5's for a 45.... The pipe can deflect 6 degrees, but we did a max of 3 degrees to allow vertical deflection along with horizontal. Just draw 20' pieces of pipe and rotate 3 degrees to get around bends...
