Is it necessary to use hole reinforcement for the DN350 hole drilled in the DN1800 circulating water pipe? The pressure is 1.0 MPa
I’m not sure, but it seems it’s necessary. A pipe of this size used for circulation can be considered as equipment; a DN350 hole should be created in this equipment as well. The pressure is quite high, so reinforcement is necessary.
It is necessary to check the thickness of the circulating water pipeline with DN1800.
It should be necessary; as for the exact size required, one can check the provisions in Article 6.4 of GB50316-2000, the \"Code for Design of Industrial Metal Piping\"
It depends on the wall thickness of the main pipe and branch pipes; in my experience, reinforcement is necessary
