4. Quality selection
The grade chosen guarantees the static strength of the construction. There are two main reasons for adapting steel quality to a given application:
the severity of implementation,
the risk of breakage in service.
The notion of quality corresponds to specified property requirements in terms of toughness, grain size and/or formability.
The first reason may be the severity of forming or welding operations, which require greater ductility or weldability. This is achieved by lowering impurity, carbon or alloying element contents.
The second reason is to guarantee toughness. The grade chosen guarantees the static strength of the construction, which is assumed to be perfect. The safety coefficients take...

Codes
CODAP is the French pressure equipment code, available from CETIM in Senlis. However, there is now a standardized European code in 4 parts:
NF EN 12952 Water-tube boilers ;
NF EN 12953 Fire tube boilers ;
NF EN 13445 Unfired pressure vessels ;
NF EN 13480 Industrial piping.
