Wuxi Yiteng Pressure Vessel Co., Ltd. specializes in the design and manufacturing of high-performance ASME U Tube Heat Exchanger solutions for industries requiring reliable heat transfer under high temperature, high pressure and severe thermal expansion conditions.
Compared with conventional heat exchanger designs, the U tube heat exchanger adopts a U-shaped tube configuration that allows the tubes to expand freely under thermal stress, making it an ideal solution for applications with large temperature differences between shell-side and tube-side fluids.
As an experienced heat exchanger manufacturer, we provide customized U-tube solutions according to customer process requirements, including heat transfer area, pressure rating, material selection and mechanical design.
Our ASME heat exchanger products are manufactured according to international standards such as ASME VIII Division 1, TEMA and GB/T151, ensuring excellent mechanical strength, corrosion resistance and long-term operational reliability.
The removable Tube bundle design enables easier inspection, cleaning and maintenance, while the precision tube-to-tubesheet connection technology improves sealing performance and prevents leakage during continuous operation.
