THE WORKSHOP

" To deliv er to cust omer s onl y quality pr odu cts w hi ch mee t the ir r equi r em en t an d ar e to th eir sa tisf acti on. "

The Quality Department, working under the above philosophy, has been assigned the following responsibilities: -- Inspection of raw material. -- Inspection at different stipulated stages of manufacture. -- Laying down testing procedures and assisting external inspection agencies. -- Prescribing and maintaining quality documents. The external agencies of inspection are inspectors appointed by the customers, including third party inspectors like RITES, LLOYD, PDIL etc.

Desig n Dep ar tm en t. The group has expertise of designing all types of heat exchangers as per national and international standards including IS, TEMA, ASME and any other standard specified by the customers. Design department initiates and supervises the required R & D work. A state of art Computer - Aided Design (CAD) facility has been installed for designing and drafting of heat exchangers.

Testi ng an d I nsp ec tion. As a part of stringent and systematic quality control check, all raw materials are inspected and test certificates are obtained for each and every supply.

We have both pneumatic and hydraulic pressure testing set up for all heat transfer equipment manufactured by us. The range of pneumatic testing is upto 20 BARS and hydraulic testing upto 50 BARS .

A hea t exchan ge r is a device for transferring heat from one fluid to another, where the fluids are separated by a solid wall so that they never mix. They are widely used in refrigeration, air conditioning, space heating, power production, and chemical processing. One common example of a heat exchanger is the radiator in a car, in which the hot radiator fluid is cooled by the flow of air over the radiator surface.

Heat exchangers may be classified according to their flow arrangement. In parallel-flow heat exhangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side. In counterflow heat exchangers the fluids enter the exchanger from opposite ends. The counter current design is most efficient, in that it can transfer the most heat. See countercurrent exchange. In a cross-flow heat exchanger, the fluids travel roughly perpendicular to one another through the exchanger.

For efficiency, heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger. The exchanger's performance can also be affected by the addition of fins or corrugations in one or both directions, which increase surface area and may channel fluid flow or induce turbulence.

A typical heat exchanger is the shell and tube heat exchanger which consists of a series of finned tubes, through which one of the fluids runs. The second fluid runs over the finned tubes to be heated or cooled.

Another type of heat exchanger is the plate heat exchanger. It directs flow through baffles so that the fluids are separated by plates with very large surface area. This plate type arrangement can be more efficient than the shell and tube. Advances in gasket technology have made the plate type increasingly practical.

Condition monitoring of heat exchanger tubes may be conducted through eddy current inspection. This is often simulated through the use of computational fluid dynamics or CFD. of whales. Arteries to the skin carrying warm blood are intertwined with veins from the skin carrying cold blood causing the warm arterial blood to exchange heat with the cold venous blood. This reduces overall heat loss by the whale when diving in cold waters.
