First pipe bend paranoia assurance

[MeldrewsMate]

Circulators are so powerful now(a)days and fittings so cheap that few bother pulling bends unless it's for aesthetic reasons.

...and for keeping down system noise.
...and for keeping down the dynamic pressure drop in gas systems.

(but apart from that Reg, what HAVE the benders ever done for us?)

 

[Gasguru]

You design the system accordingly....

When pipe benders were the norm and before building regs floor boards and joists were butchered to accommodate the long radius bends.
