B. D. Fans And Enviro Engineering

Non Metallic expansion bellows are designed, manufactured and supplied by ‘B.D.FANS’, for high temperatures and pressure, upto 3000mm of water column, to handle air and hot gases.

Non-metallic expansion joint has high temperature resistance, corrosion resistance and also has superior performance of acid and alkali resistance. Non-metallic bellows are fabricated with heat and erosion resistant flexible material, which can be a single ply of rubberized material or a composite made of multiple layers. Non-metallic expansion joints do not need maintenance in normal service life cycle. Non-metallic expansion joint can be assembled directly on installation location. If replacement is required, without removing the metal frame the fabric components can be easily wound up.

Rectangular bellows and circular bellows can be metallic or non- metallic joints.
