Stainless Steel Shell-and-Tube Heat Exchanger

Stainless Steel Shell-and-Tube Heat Exchangers | Shell-and-Tube Heat Exchange and Cooling Equipment

💡Stainless steel shell-and-tube heat exchangers feature a shell-and-tube design, with hot and cold media exchanging heat through a partition. Available in 304 or 316L stainless steel, they are used for heating, cooling, condensing, and waste heat recovery of pharmaceutical, food, and chemical process fluids.

I. Product Introduction

A stainless steel shell-and-tube heat exchanger consists of a tube bundle, a shell, tube sheets, and heads. One medium flows through the tube side, while the other flows through the shell side, and heat is transferred through the tube walls. It is widely used for heating, cooling, condensing, and evaporating process media.

II. How It Works

Hot fluids (such as steam or heat transfer oil) enter the tube side or shell side, while cold fluids (such as water or process fluid) enter the other side; heat is transferred through the tube walls. The unit can be designed with a single-pass or multi-pass configuration, and baffles can be added to the shell side to enhance turbulence and improve the heat transfer coefficient.

III. Main Structural Components

✅ Housing (carbon steel or stainless steel)

The pressure-bearing components of the equipment are made of carbon steel or 304/316L stainless steel, depending on the operating conditions of the medium.

✅ Heat exchange tubes (seamless or welded, SUS304/316L)

A heat transfer medium for both hot and cold fluids, offering corrosion resistance and excellent thermal conductivity.

✅ Tube sheet (fixed or floating head)

Fixed tube bundle; the floating-head design allows for free expansion and contraction, facilitating tube removal for maintenance and cleaning.

✅ End cap (elliptical or flat)

A flow-guiding medium that ensures uniform distribution of the fluid in the tube side.

✅ Baffles (single-arch, double-arch)

Disturbing the shell-side fluid creates turbulence, thereby improving heat transfer efficiency.

✅ Connections (inlet, outlet, drain, vent)

Dedicated ports for media inlet and outlet, drainage, and venting.

✅ Expansion joints (for large temperature differences)

Compensate for thermal expansion and contraction, and eliminate thermal stress in the equipment.

✅ Insulation layer (optional)

Reduce heat loss through the outer walls to conserve energy and lower consumption.

IV. Core Advantages

✅ Corrosion-resistant: All-stainless-steel construction, suitable for acids, alkalis, and organic solvents.

304/316L grades are suitable for a wide range of corrosive liquids and solvents.

✅ High heat transfer efficiency: Turbulent flow in the tube side and baffles in the shell side enhance heat transfer, with a K-value ranging from 500 to 2000 W/(m²·K).

The flow-diverting disturbance enhances heat transfer, resulting in a high heat transfer coefficient and a compact design.

✅ High pressure rating: Design pressure up to 4.0 MPa or higher.

Excellent pressure resistance, suitable for high-pressure steam and high-pressure process fluids.

✅ Easy to clean: The tube side can be cleaned mechanically, and the shell side can be cleaned chemically.

The floating-head, removable tube bundle facilitates internal descaling and cleaning.

✅ Long service life: Fully welded construction with no gasket leaks (except for the tube sheet).

Welded parts offer excellent sealing performance, a low failure rate, and a long service life.

V. Typical Use Cases

✅ Pharmaceutical manufacturing: Heating purified water, cooling water for injection, and preheating feed solutions.

Temperature-controlled heat exchange for extraction and solution preparation production lines.

✅ Food: Pasteurization of milk, cooling of syrup, heating of beer wort.

Sterilization and cooling equipment for dairy beverage production lines.

✅ Chemical Industry: Solvent condensation, reactor heating/cooling, and waste gas heat recovery.

Heat and mass transfer in fine chemical reaction systems.

✅ Environmentally Friendly: Wastewater cooling, steam condensate recovery.

Recover and utilize waste heat to reduce energy consumption from heat sources.

✅ Bioengineering: Cooling of fermentation tanks and cooling of culture media after sterilization.

Heat exchange equipment for temperature control in fermentation systems.
