Advantages, disadvantages and applications of Double pipe heat Exchangers

Advantages, disadvantages and applications of Double pipe heat Exchangers

Advantages:

·         Very simple to construct

·         Very easy of operation

·         U-type or hairpin constructions handle differential thermal expansions.

Disadvantages:

·         The use of two single flow areas leads to relatively low flow rates and moderate temperature differences.

Can’t be used in handling dirty fluids. (Choking problem)(Used for only clean fluids)

Why we use U-type or hairpin construction in double pipe heat Exchanger? Why do not we use straight double pipe heat exchanger?(Click Here)
