2.1 Different positions

The codes are divided into two distinct sections.

The first, common to all circuits, concerns the determination of the thicknesses to be given to the constituent elements of a piping network as a function of the pressure-temperature couple. The procedure is as follows:

• choice of material (if not imposed) according to conditions of use (temperature, fluid, environment);

• determining the permissible stress value in service ;

• determining the thickness of straight elements ;

• Determining the thickness of curved elements ;

• determination or verification of bypass...
