| High Light | U Shell Tube Heat Exchanger ，Floating Head Tube Heat Exchanger ，Tail Gas Heater Tube Exchanger | ||
YUHONG Shell and Tube Heat Exchanger – Floating Head Type, designed and fabricated in compliance with ASME Section VIII Div. 1 and certified with the ASME U Stamp. The floating head design allows for easy disassembly, cleaning, and maintenance, making it ideal for handling tail gas heating in demanding industrial applications.
While this product is a floating head type, it is worth noting the advantages of fixed tube sheet heat exchangers, which are often suitable for less complex applications:
The production of the Shell and Tube Heat Exchanger Floating Head Type involves the following key steps:
| Step | Description |
|---|---|
| Design | Custom design is created using advanced software (e.g., HTRI, PV Elite) to meet ASME and client requirements. |
| Material Cutting | High-precision cutting of raw materials (shell plates, tubes, tube sheets) using CNC plasma or laser cutting machines. |
| Shell Rolling | Shell plates are rolled into cylindrical shapes using hydraulic rolling machines and welded longitudinally. |
| Tube Sheet Fabrication | Tube sheets are drilled with high precision to align with the tube arrangement and center distances. |
| Tube Insertion | Heat exchange tubes are inserted into the tube sheets according to the specified arrangement. |
| Tube Expansion | Tubes are expanded into the tube sheets using mechanical or hydraulic tube expansion tools to ensure a leak-free seal. |
| Head Assembly | Floating heads and stationary heads are fabricated and assembled, ensuring alignment with the shell and tube bundle. |
| Sandblasting | All components are sandblasted to remove surface contaminants and prepare for coating or painting. |
| Welding | Critical welds (e.g., head-to-shell, nozzle connections) are completed by qualified welders following ASME standards. |
| Testing | Hydrostatic, pneumatic, and nondestructive testing (NDT) ensure the exchanger meets pressure and quality requirements. |
| Final Assembly | Components are assembled, and final inspections are carried out before delivery. |
The tube arrangement and center distance tolerances are critical to the heat exchanger's performance.
| Parameter | Details |
|---|---|
| Tube Arrangement | Common layouts include triangular (30°) and square (90°) for optimal heat transfer and flow. |
| Tube Pitch (Center Distance) | Typically 1.25x the tube outer diameter (OD) to ensure proper fluid flow and mechanical strength. |
| Tolerances | Tube-to-tube spacing tolerance: ±0.5 mm. Tube sheet drilling tolerance: ±0.2 mm. |
