Can’t manholes be installed on storage tanks for flammable and explosive materials? To reduce the possible number of leakage points
Shouldn’t more measures be put in place for flammable and explosive materials? It is necessary to enter the equipment regularly for inspections. The standards require that horizontal storage tanks over 6m in length must also be equipped with two.
Manholes are designed according to the size of the storage tank and inspection requirements
HG/T20583 does not contain such provisions regarding the installation of manholes and inspection holes. Reducing leakage points should be done while complying with design requirements, standards, and specifications
I haven’t seen any standards stating that manholes cannot be installed on storage tanks for flammable and explosive materials.
Chemical plants and refineries still mainly handle explosive materials! Storage tanks all have manholes, right!
The hydrogenation reactor also has manholes
