INstallation
Example:
- Specification: if the nominal flow rate is 10 m
3
/hthe ideal flow velocity is between
2 and 3 m/s
- Solution: intersection between flow rate and flow velocity in the graph gives the
appropriate pipe diameter, DN40 (or DN50 for the asterisked fittings).
* For the fittings:
- with external thread connections acc. to SMS 1145 ;
- with weld end connections acc. to SMS 3008, BS 4825 / ASME BPE
or DIN 11850 Range 2;
- with Clamp connections acc. to SMS 3017 / ISO 2852,
BS 4825 / ASME BPE or DIN 32676.
