Dear Suphasin
Dear Surin
The installed piping keeps it.
About uninstalled piping or unmanufactured piping, Guardfire must modify the MH checked drawings at site with
considering the interference or valve operability.
Examination and decision about route for pipe connected to the pipe which has been already installed at site shall be done by Guardfire.
When Guardfire examine and decide the piping route, the piping route drawings by Guardfire shall be based on MH checked drawings.
Best Regards
