4.1 Piping. Hoses. Fittings. Rotating joints
Generally speaking, connections between components must satisfy the following two rules:
absolute tightness up to very high pressures ;
minimum pressure drop for a given size or price.
For all these elements, we find the notions of :
safety coefficient for pressure resistance ;
permeability or equivalent cross-section for head losses.
The safety factor is the ratio of the burst or leak pressure at ambient temperature to the working pressure. The usual coefficient is 3.5,...
