TUBE EXPANSION

TUBE EXPANSION

Abstract:

Tube expansion means elimination of diameter differences between two pipe end and are joint with welding .The process is carried out to prevent stress induced in the tubes due to expansion and contraction. The process is also useful to avoid misalignment.

In this process tension is created between tube and tube sheet to make the joint leak proof. In some cases buckling and bends are induced in the tubes, which are minimized by tube expansion.

Tube expansion have minimum distortion of tube sheet and have high reliability and reduces stress corrosion.
