- Werecommend
for the calculation of the operating
pressure in piping systems to multiply
the in the table contained operating
pressure with a system reduction
coefficient fs=0.8 (this value contains
installation-technical influences
such as welding joint,flange or
also bending loads.).
- These operating
pressure have to be reduced by the
corresponding reducing coefficients(see
page 19-23)for every application.
