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.
JIS B2220 Slip On Hubbed Flange
The JIS B2220 slip on hubbed flange has three types in the nominal pressure 20K and 30K,as follows:
| Classification of flange | Type | Figure |
