High-Efficiency Shell and Tube Heat Exchanger for Industrial Processes

Overview

Engineered with precision-welded tube bundles and a heavy-duty shell, this exchanger features a modular design for easy maintenance and customizable configurations. Available in carbon steel, stainless steel (304/316L), and exotic alloys (Hastelloy, Inconel), it balances thermal performance with corrosion resistance, making it ideal for chemical, petrochemical, and power generation industries.

Features

Enhanced Thermal Performance

Tubular Design: Triangular/tri-square tube layouts increase heat transfer area by 20% compared to square layouts, achieving NTU (Number of Transfer Units) up to 8.

Baffle Configuration: Segmental or orifice baffles optimize fluid turbulence, reducing fouling and improving overall heat transfer coefficient (up to 450 W/m²K for liquid-liquid applications).

Durable Construction

Material Options: Shell and tubes available in carbon steel (for general use), 316L stainless steel (corrosive environments), and nickel-based alloys (high-temperature/high-pressure scenarios).

Pressure Ratings: Designed for shell-side pressure up to 100 bar and tube-side pressure up to 200 bar, compliant with ASME BPVC Section VIII Div. 1.

Modular & Maintenance-Friendly

Floating Head Design: Eliminates thermal stress in high-temperature applications, allowing tube bundle expansion without deformation.

Quick Access Ports: Large manways and flanged connections enable easy tube cleaning (mechanical or chemical) and bundle replacement.

Customization Capabilities

Tube Sizes: 10-50mm outer diameter with wall thickness 1-5mm, customizable for viscous or particulate-laden fluids.

Nozzle Configurations: Radial or tangential nozzles optimized for laminar/turbulent flow requirements.

Application

Chemical Processing:

Cooling/heating of reactor feeds, distillation column overheads, and solvent recovery systems.

Heat recovery in waste heat boilers and steam generators.

Petrochemical & Refining:

Crude oil preheating, lube oil cooling, and condenser applications in refinery units.

Heat exchange in ethylene plants and catalytic reforming processes.

Power Generation:

Steam condensation in power plants, geothermal heat transfer, and turbine oil cooling.

Food & Beverage:

Pasteurization systems, milk cooling/heating, and syrup concentration processes (316L stainless steel models compliant with FDA 21 CFR Part 177).

FAQ

Q: What is the typical fouling resistance of the exchanger?

A: Smooth tube surfaces and baffle spacing minimize fouling; optional titanium tubes or anti-fouling coatings further enhance resistance in scaling environments.

Q: Can the exchanger handle 两相流 (two-phase flows)?

A: Yes, specially designed for gas-liquid or vapor-liquid flows with optimized baffle spacing and tube support plates.

Q: What is the lead time for custom material configurations?

A: Standard models ship in 4-6 weeks; custom alloys or configurations require 8-12 weeks due to material sourcing and engineering validation.

Q: How is the tube-to-tube sheet joint tested?

A: All joints undergo hydraulic pressure testing (1.5x design pressure) and liquid penetrant inspection to ensure leak-tight integrity.
