During duct fitting the duct should be supported as follows:
1. 100 Dia - 250 Dia on 7 metre centres.
|
2. 315 Dia - 900 Dia on 5 metre centres.
| ||||||||||||||||
Supports should be installed to provide lateral stability to the entire piping system. Each installation is unique and should be evaluated.
