Deflection in DIP
Deflection in DIP
(OP)
I was curious what is considered the maximum deflection allowable for construction/design of DIP water mains. I know this will vary by location, but I'm just looking for some general idea. I'm talking about standard AWWA C900 DIP. I've heard from 2-5 degrees. Does that sound about right?

If I need to make a 9 degree bend, is there any way to introduce another 2.25 degrees into the bend to use a standard 11.25 degree bend?
I'm just a little confused. Having never worked on pipe installation in the field, I'm unsure how they go about achieving bends that are outside of the standard bend range. Are there smaller bends? Do they fit the pipes at a slight angle (this is what I meant by "deflection", my bad), if so how large can this angle be? Etc?
Anyway, I asked the wrong question. Hopefully this will clarify what I'm asking. Any help would be much appreciated. Oh yeah, also it's polyethylene-encased (not lined) and lined with standard cement.
