| Bellows Expansion Joints are used in almost all industries and especially in the following : |
| |
| » Steel Plants ::.. |
In Blast Furnaces in Tuyere Stock high-pressure hot air ducting and pipelines, in other plant e.g. Sinter plants, Fume gases sulphurisation, Captive Boilers, Coke Oven Batteries, B.F. Gas, Furnace exhausts, Fume extraction systems etc. |
| |
| » Petroleum Refineries ::.. |
Apart from the standard applications, the Bellows Expansion Joints are used in pipelines, Heat Exchanger Shell, Reactors, Columns etc. and in FCC units in Refineries. |
| |
| » Cement ::.. |
| All the major hot air ducting carrying dry cement, Preheater, Boiler, Kiln, Hooper, Tertary Air Duct (T.A. Duct), R.A. duct, ESP use large diameter circular and rectangular Bellows. |
| |
| » Power Plants ::.. |
In Thermal Power plants piping & duct connections, Ash Handling plants and Economiser, Turbines and steam carrying ducting. In Nuclear Power plants, usage of Bellows is much greater, e.g. in Pipe penetration, Fan Isolators, Chimney seals etc. |
| |
| » Other Industries ::.. |
Apart from the above major industries, others viz. Chemicals & Fertilizers, Ship buildings, small power plants, Diesel Locomotives etc. use Bellows Expansion Joints for connecting equipment to pipelines and ducting for correcting misalignment and as vibration isolator.
Highly critical application Bellows are being imported by the major industries which are now being indigenized.
