Lekage heat transfer can be varied by refactory brick on the inner and outer surface of the steel pipe ?

Question

Assertion (A): The leakage heat transfer from the outside surface of a steel pipe carrying hot gases is reduced to a greater extent on providing refractory brick lining on the inside of the pipe as compared to that with brick lining on the outside.                               (IES-00)

Reason(R): The refractory brick lining on the inside of the pipe offers a higher thermal resistance.
