Example

Rattay stainless steel corrugated hose DN 50 Type HR I/S, on both sides screw connections made of stainless steel, Fig. 114.

Operating data

  • = 48°

Calculation:

l = 111 mm
r = 310 mm see hose table
z = 100 mm see table
a = 360 (1 - cos 48°) + (111 + 100) sin 48° = 276 mm
NL = 360 mal w mal 48 durch 180  + 2 (111 + 100) = 723 mm (Order length NL = 730 mm)

E = 310 · sin 48° + (111 + 100) · (1 + cos 48°) = 620 mm
