ASME Certificated Shell And Tube Type Heat Exchanger Fixed Tubeplate Type for Water Heater
YUHONG GROUP specializes in the manufacturing of TEMA C type heat exchangers. Our expertise is exemplified in units designed for water (shell side) and steam (tube side) service, operating at 29.5/50°C and 154/295°C respectively, with design pressures of 7 kg/cm². We ensure robust construction with a 1.5mm corrosion allowance and strict adherence to test pressures (10.5 kg/cm²). The TEMA C classification allows for flexible, efficient, and reliable design, making our heat exchangers ideal for critical applications in power generation and process industries.

Testing Requirements
Pressure Testing: This unit will be subjected to a test pressure of 10 kg/cm² for shell and steam.
Radiography: Radiographic tests will be performed to detect any hidden flaws or discontinuities in welds, ensuring structural integrity.
Heat Treatment: Post-fabrication heat treatment is essential to relieve stresses introduced during manufacturing and improve the overall mechanical properties of the materials.
Corrosion Testing: Specific tests will be conducted to evaluate the resistance of materials to corrosive elements.
Specifications
Fluids Processed: The heat exchanger manages two primary fluids: water and steam.
Operating Temperature: The service temperature for water ranges from 29.5°C to 50°C, while steam can reach temperatures as high as 295°C.
Operating Pressure: The operating pressure for water is designed at 3.5 kg/cm², and for steam, it is 10 kg/cm².
