Expansion Bellows

We offer a wide range of expansion bellows that are manufactured to provide better security & flexibilty. Our bellows are extensively used for absorbing the movement in pipes that are caused because of the thermal expansion and vibrations.  These are fabricated by using annealed  321 stainless steel sheet stock that is rolled into a tube and seam welded. Besides this, titanium and 316 stainless steel are also used to fabricate the bellows as per the client’s requirements. our expansion bellows are used for the following:
  • Diesel generator exhuast and boiler fuel
  • High and low-pressure turbine piping
  • Main feed pump suction
  • Propeller shaft air system
  • Condensate pump suction
  • Saturated and superheated steam
