Hebei Haihao Group can manufacture the JIS B2220 slip on flange in high quality,which 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 | |
Type B | ||
Type C |
In the different pressure the JIS B2220 slip on hubbed flange has different size,as follows:
Pressure | JIS B2220 SOH Flange Size |
5K | 450A-1000A |
10K | 250A-1000A |
16K | 10A-600A |
20K |
TypeA: 10A-600A; Type B: 10A-50A; Type C: 65A-600A |
30K |
TypeA: 10A-400A; Type B: 10A-50A; Type C: 65A-400A |
