Thanks

RE: maximum pipe deflection
If you have a 20 foot span, 1/2 inch is equal to L/240, a common limit for beam deflection where too much liquid pooling is avoided.
L/180 is a typical deflection limit for beams under motion sensitive floors and equipment.
L/360 is a typical maximum deflection limit for normal use floors.

RE: maximum pipe deflection
I guess aesthetics, stability or dynamics, as well as effects on specific coatings or linings involved might also be considerations in some at least local stipulations with regard to mid-span deflection.
RE: maximum pipe deflection
It creates far fewer questions if the deflection is kept below limits where people don't really notice it.

NOTE: In most cases deflection will determine the span length. These span lengths are acceptable for horizontal runs of carbon, alloy or stainless steel pipe with the same O.D., equal or greater pipe wall thickness and for temperatures up to 750 degrees Fahrenheit. Piping with concentrated weights and risers require lesser span lengths and then allowables for stress and suggested deflection given in B31.1 Power Piping Code govern.
Span lengths may be found by inserting data in the unshaded areas.
