Heat Exchanger Manufacturing
Optimum Heat Transfer and High-Efficiency Process Solutions
DRS Makina manufactures high-efficiency, long-lasting heat exchangers fully compliant with international standards (TEMA, ASME, EN) for industrial processes where heat transfer is critical, such as the petrochemical, energy, chemical, food, and paper industries. The thermal and hydraulic requirements of your system are analyzed by our expert engineering team, and the mechanical design and production of the most suitable shell and tube heat exchangers for the process are ensured.
Design Accuracy and Full Compliance with TEMA Standards The performance of heat exchangers depends on accurate thermal calculation and flawless mechanical design. The optimum surface area is calculated by the DRS Makina design department according to fluid phases (liquid, gas, steam), operating temperatures, and corrosion rates. Mechanical designs executed in accordance with TEMA (Tubular Exchanger Manufacturers Association) classifications (Class R, C, B) and ASME Section VIII rules are verified with advanced engineering software prior to production.
Advanced Production Techniques and Precision Craftsmanship Tube-to-tubesheet connections, the most critical point of heat exchangers, are executed with great precision targeting zero leakage. Depending on project requirements, tube expansion, automatic orbital welding, or a combination of both methods are applied by our certified experts. A wide manufacturing range is offered in the following heat exchanger types:
- Fixed Tubesheet Heat Exchangers
- U-Tube Heat Exchangers
- Floating Head Heat Exchangers
- Kettle Type Reboilers and Condensers
Material Variety and Corrosion Control Accurate material selection is implemented against the severe corrosive effects encountered during heat transfer. In our manufacturing processes, a wide range of materials such as Carbon Steel, 304L/316L/316Ti Stainless Steel series, Duplex, Superduplex, Copper Alloys, Brass, and Titanium are processed with full traceability certificates.
Performance and Leak Tightness Testing Each completed heat exchanger is subjected to rigorous testing by our quality control department to ensure maximum field performance. In addition to hydrostatic and pneumatic tests performed separately for the tube bundle and shell sides, equipment reliability is certified through precise gas leak tests and non-destructive testing (NDT) prior to delivery.
