Note: ① The height H of the manhole is determined by the diameter of the equipment being not less than the nominal diameter of the manhole. If there are special requirements, it is allowed to change, but the changed H size must be indicated and the total weight of the manhole must be verified.
② The nominal diameters in brackets in the table should not be used as much as possible. Marking example:
Nominal pressure Pg6, nominal diameter Dg450, H, = 280, using Class I material, A-type sealing surface horizontal cover manhole, its specified marking symbol is:
Manhole AI'Pg6, Dg450, JB583-79 (Note) H, = 270 (non-standard size) of the above example manhole, its specified marking symbol is: Manhole AIPg6, Dg450, H = 270, JB583-79 (Note) Note: Write the construction drawing number in the equipment assembly drawing. 2. The technical conditions should comply with the provisions of JB2555-79 "Classification and Technical Conditions of Carbon Steel and Low Alloy Steel Manholes". 39
