Finned Tubes By Pishori Lal Refrigration & Engg. Co.

We are involved in providing fine quality Finned Tubes which are used in applications involving the transfer of heat from a hot fluid to a colder fluid through a tube wall. The rate at which such heat transfer can occur depends on three factors:

(1) the temperature difference between the two fluids;
(2) the heat transfer coefficient between each of the fluids and the tube wall; and
(3) the surface area to which each fluid is exposed.

In the case of a bare (unfinned) tube, where the outside surface area is not significantly greater than the inside surface area, the fluid with the lowest heat transfer coefficient will dictate the overall heat transfer rate. When the heat transfer coefficient of the fluid inside the tube is several times larger than that of the fluid outside the tube (for example steam inside and oil outside), the overall heat transfer rate can be greatly improved by increasing the outside surface area of the tube. In mathematical terms, the product of heat transfer coefficient for the outside fluid multiplied by outside surface area is made to more closely match the product of the inside fluid heat transfer coefficient multiplied by tube inside surface area.

We offer these Finned Tubes at most affordable prices to our precious customers.
