Yuhong Group Co., Ltd. designs and manufactures complete thermal systems - shell & tube heat exchangers (TEMA heat exchanger designs), pressure vessels, and air coolers - while also supplying the critical internal parts that keep them running: Fin Tube, Furnace Tube, Heat Exchanger Tube, Stainless Steel Seamless Tube, Nickel Alloy Tube, Copper alloy tube, heat exchanger tubesheet, and heat exchanger tube bundle. Whether you need a new exchanger or a replacement bundle, we deliver ASME‑compliant solutions.
Our carbon steel shell & tube heat exchanger is the workhorse of non‑corrosive and mildly corrosive services - water, steam, oil, gas, and many hydrocarbons. Fabricated from ASME SA179 seamless tubes and SA266 Gr.2 forged tubesheet, it provides efficient heat transfer, long service life, and easy maintenance. The entire heat exchanger tube bundle can be extracted (in floating head or U‑tube designs) for cleaning or replacement, minimizing downtime.
| Component | Role in the Heat Exchanger | Why Material Selection Matters |
|---|---|---|
| Heat Exchanger Tube | Primary heat transfer surface; carries one fluid inside, while the other flows outside | ASME SA179 carbon steel offers excellent thermal conductivity and formability for rolling into tubesheet. |
| Fin Tube | Optional add‑on to increase surface area; used when gas or low‑HTC fluid is on the outside | Fins boost heat transfer by 200‑400%; available in carbon steel, aluminum, or stainless steel. |
| Furnace Tube | Heavy‑wall tube for high‑temperature service (e.g., fired heaters, waste heat recovery) | Chrome‑moly alloys (P5, P9, P11) resist creep and oxidation at >500°C. |
| Stainless Steel Seamless Tube | For corrosive or high‑purity services (chemical, food, pharma) | Grade 304/304L or 316/316L resists chloride pitting and general corrosion. |
| Nickel Alloy Tube | Extreme environments - seawater, acids, high‑chloride, high‑temperature | Alloys like Monel 400, Incoloy 825, Hastelloy C276 provide unmatched corrosion resistance. |
| Copper Alloy Tube | Seawater and brackish water coolers (power plants, ships, offshore) | C70600 (90/10 Cu‑Ni) resists erosion, biofouling, and impingement attack. |
| Heat Exchanger Tubesheet | Holds all tubes, seals the tube side from the shell side | Forged SA266 Gr.2 (carbon steel) or stainless steel cladding for corrosive tube fluids. |
| Heat Exchanger Tube Bundle | Complete assembly of tubes, tubesheets, baffles, tie rods; the removable core | Floating head or U‑tube bundles allow full withdrawal for mechanical cleaning or retubing. |
Not every project needs a complete exchanger. Many customers only require replacement tube bundles, a new tubesheet, or a shipment of fin tubes for field maintenance. By offering both full equipment and individual parts, Yuhong Group serves:
A heat exchanger tube bundle is subject to gradual degradation - corrosion, pitting, erosion, or vibration fatigue. Plant operators face a choice:
| Condition | Recommended Action | Cost Consideration |
|---|---|---|
| <10% of tubes plugged or leaking | Retube only the damaged tubes (if accessible) | Lower short‑term cost, but requires skilled labor and same tube material. |
| 10‑30% of tubes affected | Replace the entire tube bundle | Eliminates future failures; new bundle matches original design. |
| >30% tubes damaged, or tubesheet corroded | Replace complete bundle, possibly with upgraded material | Most cost‑effective long‑term solution, especially if upgrading to stainless steel or alloy tubes. |
| Shell side also corroded or leaking | Consider complete exchanger replacement | Avoid repeated repairs and downtime. |
Send your inquiry to jimmy@steelseamlesspipe.com. Provide a drawing, a list of failed tubes, or your process conditions. Yuhong Group will quote you either a complete carbon steel shell & tube heat exchanger or the specific components you need - tube bundle, tubesheet, fin tubes, seamless tubes - all with full material traceability and ASME compliance.
