AAHANA GIFFARD SYSTEMS

Double tube heat exchangers (also known tube-in-tube) are designed whereby one tube is concentrically positioned within a larger tube. The double tube composition allows for unrestricted flow of product, making it the ideal heat exchanger for viscous products. The product flows through the inner tube and the service fluid flows through the surrounding shell.

Recuperator systems are heat exchangers that produce hot air by utilizing the energy of high-temperature waste flue gas generated in furnace systems, boiler systems and various processes. Recuperators various heating needs of facilities such as combustion air preheating and ambient heating are met and energy consumption is minimized. Compared to economizers, they have larger surface area and dimensions at the same heat capacity. They can be manufactured as finned tube and straight tube. Recuperator heat exchangers can be made from numerous materials steel, stainless steel and other special materials.

We are specialized to design and fabricate carbon, stainless or exotic steel pressure vessels mainly for oil&gas, petrochemical and power industries in accordance with ASME Sec VIII Div.1 and EN Norms with CE mark. Most of the industrial processes need to store fluids and materials of different kinds and with different purposes.

We design and manufacture products based on the project sent by our customers or according to customer requirements. Calculations, designs and projections according to customer demand and in accordance with ASME Code Section VIII Div 1 and 2 (American Society Mechanical Engineers), API 661, API 650 (American Petroleum Institute), TEMA (Tubular Exchanger Manufacturers Association), AD-MERKBLAATTER, CODAT, DIN, EN 13445, PED 2014/68 / AB and TSE. The most common processes in the Oil & Gas, Petrochemical & Chemical, Food & Beverages and Heavy & Light Industry require a significant number of equipment to exchange heat or to storage different fluids or components. The fluid can be either liquid or gas, and one of each flows into the tube and the other flow out of the tube is used to boil, condense or cooling the fluid.
