Note:

(1)The Flange connection size is according to JB/T81-1994 or JB/T79-1994(PN1.6、PN2.5)\GB/T9119-2000(PN4.0).

 

(2)Nominal diameter DN10~50mm,flange dimension at a nominal pressure of PN4.0 Mpa.

 

(3)Of the flange dimensions in the range of nominal diameterDN65~150..The item bearing parentheses is the flange dimension for a nominal pressure of PN2.5Mpa and PN4.0Mpa.

 

(4) Of the flange dimensions for nominal diameter DN200~300,items bearing

parentheses is the flange dimension for a nominal pressure of PN25Mpa.

 

(5)In normal cases, flanges are manufactured as per 1.6Mpa.
