La longueur de la portée d´un tube   

Calcul de la longueur de la portée




Calculation of Pipe Span with Beam Theory

  1. Determine the weight of the medium by entering its density.
  2. Determine weight, geometry, flexibility and strength of the pipe. The pipe takes all forces.
  3. Determine the weight of the shell by entering is thickness and its density
  4. Last but not least choose the maximum deflection you would accept. Calculation will show the corresponding bending stress.

Deflection L and pipe span will be calculated for the one span beam tilt mounted (worst case) and the one span beam fixed at both ends (best case). Values will be calculated for 10%, 50% and 100% of the maximum bending stress.
