Shell and Tube Heat Exchanger Feed Water Heater Sectional Assembly for Oil and Gas Industry

Shell and Tube Heat Exchanger Feed Water Heater Sectional Assembly for Oil and Gas Industry

YUHONG is a premier manufacturer specializing in the custom engineering and fabrication of robust, high-performance Shell and Tube Heat Exchangers. With a foundation built on decades of mechanical engineering excellence, we serve as a critical partner for industries requiring reliable thermal management under demanding conditions. Our commitment extends beyond manufacturing; we provide comprehensive thermal solutions from initial design consultation to after-sales support.
Our certified workshops are equipped with heavy-duty machinery for rolling, welding, and tube bundling, ensuring precision in every component. We adhere to stringent international design and fabrication codes, including ASME Section VIII Division 1, TEMA standards (R, B, and C classes), and the PED 2014/68/EU. Every unit undergoes rigorous quality checks and non-destructive testing (NDT), such as radiography and ultrasonic testing, to guarantee safety, durability, and leak-free operation. At YUHONG, we build heat exchangers that are engineered to last, delivering consistent performance and maximizing your return on investment.
