The JIS B2220 slip on flange in our company could be divided two different types:JIS B2220 slip on hubbed flange,JIS B2220 slip on plate flange.The JIS B2220 slip on plate flange is just like a ring with bolt holes,the JIS B2220 slip on hubbed flange is like a plate flange with a neck or hub,the cost is higher than the slip on plate flange,but slip on hubbed flange can supply a better joint quality and reinforcement.
The JIS B2220 slip on hubbed flange has three types in the nominal pressure 20K and 30K,as follows:
|Classification of flange||Type||Figure|
|JIS B2220 Slip On Hubbed Flange||Type A|
The JIS B2220 slip on hubbed flanges size are according to the pressure,different pressure the nominal size are different,as follows:
|Pressure||JIS B2220 SOH Flange Size|
Type B: 10A-50A;
Type C: 65A-600A
Type B: 10A-50A;
Type C: 65A-400A
