A Flange is used for connecting pipes, valves, pumps and other equipment to form a Pipe work system. It also facilitates easy access for cleaning, inspection or modification. Flanges are usually welded or screwed into such systems and then joined with bolts. 
The basic types of flanges used in Sugar plants, Water, Sewage, ETP plants, Fire Fighting system, HVAC plant, Cooling towers and Utility plants pipelines are: 

• Slip-on raised face (SORF) or Slip-on flat face (SOFF) or Ring flanges or Collars 
  
• Blind raised face (BLRF) 
  
• Non-radius / radius screwed flanges 
  
• Threaded Flanges 
  
• Hot Dip Galvanized Flanges /GI Flanges 
  
• lap joint flanges
