3. 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 has minimum distortion of tube sheet
and has high reliability and reduces stress corrosion.
4. DEFINATION OF TUBE EXPANSION
Definition:-Elimination of diameter difference between
the two pipe ends to be joined with welding (girth weld).
