Note: ①Manhole size H is determined based on the true diameter of the equipment being not less than twice the nominal diameter of the manhole. If there are special requirements, changes are allowed, but the changed size must be indicated and the total weight of the manhole must be corrected.
②The nominal diameters in brackets in the table should not be used as much as possible. Page 5 of 7
Marking example:
JB584-79
Nominal pressure P.25, nominal diameter D. 450, H, 250, using Class IV materials, C-type sealing surface of the rotating blue butt welding flange manhole, the specified marking symbol is:
manhole CIVPg25, Dg450, JB584-79 (Note) H1 = 280 (non-standard size) of the above example manhole, the specified marking symbol is: manhole CIVP.25, Du450, H, = 280, JB584-79 (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 and Handholes". 46
