Are you facing efficiency losses due to a fouled or corroded exchanger core? Replacing the internal components is the most cost-effective way to restore your system.
As a leading global manufacturer, Yuhong Group supplies fully assembled, ready-to-install carbon steel heat exchanger tube bundles designed to TEMA and ASME Section VIII standards. We provide direct-replacement cores that fit seamlessly into your existing shell, reducing downtime by up to 60% compared to buying a complete new heat exchanger.

Every carbon steel tube bundle we fabricate is custom-engineered to match your exact operational parameters or original equipment drawings (OEM specs).

• Tube Material: ASME SA179 seamless, cold-drawn carbon steel (offers optimal thermal conductivity and precise outer diameter for rolling).

• Tubesheet Material: High-strength ASME SA266 Gr.2 forged carbon steel or SA516 Gr.70 plate.

• Baffle Configuration: Customized SA516 Gr.70 segment baffles, precision-drilled to prevent tube vibration and optimize shell-side fluid turbulence.

• Tube Layout & Pitch: Optimized triangular ($30^circ$ or $60^circ$) or square ($90^circ$) pitch arrangements based on your thermal design and cleaning requirements.

• Tube-to-Tubesheet Joints: High-precision hydraulic expansion (rolling) with optional seal welding or strength welding for high-pressure or lethal gas applications.

In heavy industries like petrochemical refining and power generation, time is money. Ordering a replacement core offers distinct financial and operational advantages:

• Significant Cost Savings: A replacement tube bundle typically costs only 30% to 50% of a brand-new shell-and-tube heat exchanger.

• Drastically Reduced Lead Times: We deliver custom carbon steel bundles in 4 to 6 weeks, compared to 12 to 20 weeks for a complete pressure vessel.

• Zero Piping Modifications: The new bundle is reverse-engineered to slide directly into your existing shell. No need to modify inlet/outlet nozzles, foundations, or structural steel.

• Immediate Efficiency Restoration: Eliminates fouling resistance, instantly restoring your original heat transfer coefficients ($U$-values) and reducing energy consumption.

Choosing the correct metallurgy is critical for the lifespan of your equipment. While Yuhong Group supplies premium alloys, ASME SA179 Carbon Steel remains the industry gold standard for specific process environments.

1. Closed-Loop Cooling: Ideal for treated industrial water, steam condensation, and boiler feedwater circuits.

2. Non-Corrosive Hydrocarbons: Widely used in oil and gas refineries for crude preheaters and gas aftercoolers.

3. Moderate Temperature Limits: Excellent mechanical properties for continuous operation under 400°C.

To ensure your replacement shell and tube bundle fits perfectly on the first try, our engineering team requires one of the following:

1. Original Manufacturer Drawings (As-Built Drawings): The most reliable method to duplicate tube counts, baffle pitches, and tubesheet thicknesses.

2. Physical Sample (Old Bundle): You can ship your fouled bundle to our facility. We will reverse-engineer all dimensions using precision laser scanning.

3. Shell Internal Dimensions: If drawings are lost, we can assist you in calculating the exact outer bundle diameter (OटीL) based on your shell ID.

⚠️ Critical Engineering Tip: When ordering, always verify your baffle orientation (horizontal vs. vertical cut) to ensure proper fluid drainage, and state whether you require an impingement plate to protect outer tubes from high-velocity inlet erosion.

Beyond fully assembled tube bundles, Yuhong Group is a single-source manufacturer for individual pressure vessel components:

• Heat Exchanger Tubes: Seamless stainless steel tubes, nickel alloy tubes, copper alloy tubes, and carbon steel boiler tubes cut-to-length.

• Extended Surface Tubes: High-fin and low-finned tubes for air-cooled heat exchangers.

• Machined Components: Drilled and grooved tubesheets, baffles, tie rods, and structural spacers.
