Alloy Steel Tubular Heat Exchanger

Product Introduction

Alloy Steel Tubular Heat Exchanger is a heat exchange device made primarily of alloy steel, designed for high-temperature or corrosive working conditions.

Core Structure

1. Tube Bundle: Seamless or welded tubes made of alloy steel (such as 304/316L stainless steel, duplex steel, Inconel, Hastelloy, etc.).
2. Tube Sheet: Typically made of alloy steel or composite materials compatible with the tube bundle (alloy steel overlay).
3. Shell: Depending on the design pressure and cost, the shell can be made of carbon steel lined with alloy, composite plates, or a full alloy structure.
4. Tube Box and End Caps: For distributing the flow medium; can use a structure similar to the shell.
5. Baffles: Optimize the shell-side flow field and improve heat transfer efficiency.
6. Expansion Joint (Optional): Used to compensate for the thermal expansion difference between the tube bundle and the shell caused by temperature differences.

Product Features

High Temperature and High Pressure Resistance: 15CrMo, 12Cr1MoVG alloy steel materials, long-term operation under 450°C/10MPa conditions.
Corrosion Resistance: Cr and Mo alloy elements form a dense oxide film, effectively blocking the penetration of corrosive media.
Customized Design: Heat exchange area, number of tube passes, baffle spacing, nozzle orientation, and other parameters can be customized.
Easy Disassembly Structure: The tube bundle adopts a floating head structure and can be wholly withdrawn, facilitating quick cleaning and maintenance.
