Safety factor for dynamic demand.

* Flows above a Reynolds figure of 5 x 104 can create harmful turbulences in corrugated hoses. Please contact our engeneering department.

Calculation example

Tuboflex® Stainless steel corrugated hose material 1.4301, MW 22 U 1 - DN 50 is installed at temperature of 300°C. It is exposed to low vibration and frequent uniform motion with pulsating and swelling flow.
