Carbon Steel Heat Exchanger Tube Bundle | ASME SA179 Tubes & SA266 Gr.2 Tubesheet | Direct Replacement for Shell & Tube Heat Exchangers – Easy Maintenance
Complete Heat Exchanger Solutions

Yuhong Group Co., Ltd. supplies high-quality thermal equipment including shell & tube heat exchangers (TEMA heat exchanger designs), pressure vessels, air coolers - and every critical internal component. We deliver ASME-compliant parts that restore performance and extend equipment life.

Product Focus: Carbon Steel Tube Bundle

The carbon steel tube bundle is the removable core of a shell & tube heat exchanger, consisting of ASME SA179 seamless tubes, SA266 Gr.2 forged tubesheet, baffles, tie rods, and spacers. Designed as a direct drop-in replacement for existing units in non-corrosive or mildly corrosive services.

Key Components & Their Roles
Component Material (Typical) Role in Equipment Performance
Heat Exchanger Tube ASME SA179 (carbon steel) Carries tube-side fluid; primary heat transfer surface. Typically hundreds of tubes per bundle.
Fin Tube (optional) Carbon steel + aluminum fin Increases surface area by 3-5* for gas or low-HTC fluids, boosting heat transfer without resizing the shell.
Furnace Tube Heavy-wall chrome-moly (P5, P9) For high-temperature sections; resists creep and oxidation in waste heat recovery applications.
Heat Exchanger Tubesheet SA266 Gr.2 forged Holds all tubes; separates shell-side from tube-side fluid. Precision-drilled for leak-tight tube rolling.
Baffles SA516 Gr.70 Direct shell-side flow across tubes, support tubes against vibration, increase turbulence.
Tie Rods & Spacers Carbon steel (SA193 B7) Hold baffles at correct spacing; ensure bundle rigidity during shipping and operation.
Sealing Strips Carbon steel Block shell-side fluid from bypassing the bundle periphery; maximize thermal efficiency.
Benefits of New Carbon Steel Tube Bundles
  • Restores original heat duty after years of fouling, corrosion, or erosion
  • Eliminates costly repairs of old bundles with plugged tubes or damaged components
  • Upgrade opportunity - improved materials or enhanced fin tubes for higher capacity
  • Fast turnaround - manufacturing to your specifications in 4-6 weeks
Technical Excellence
  • Precision tube-to-tubesheet joints: Hydraulic rolling + optional seal welding for leak-proof connections
  • Impingement protection: Stainless steel impingement plate for high-velocity inlet streams
  • Vibration-resistant design: Optimized baffle spacing to prevent tube fretting and fatigue
  • Full material traceability: Mill Test Certificates (MTC) for all components
When to Replace Your Tube Bundle
Situation Repair Viable? Why Replace Instead
<5% tubes plugged Yes, repair acceptable Replacement not yet justified
5-15% tubes plugged Borderline Loss of surface area reduces duty; replacement restores original performance
>15% tubes plugged No Significant duty loss; future plugging will accelerate
Tubesheet face corroded/grooved No New tubes will not seal properly against old tubesheet
Frequent tube leaks near inlet No Impingement erosion - design flaw requiring proper impingement plate
Proactive Replacement Indicators
  • Rising pressure drop (tube side or shell side) by >30% above clean baseline
  • Exit temperatures moving away from design values despite normal flow rates
  • Visible weeping at tube-to-tubesheet joints (dye penetrant test)
  • Vibration noise or tube fretting marks at baffle supports
Carbon Steel Advantages
  • Most economical material for clean water, steam, light hydrocarbons
  • Easy to fabricate - short lead times
  • Fully repairable - carbon steel tubes can be re-rolled or seal-welded in the field
  • Proven longevity - 15-20 years with proper water treatment
Customization & Component Supply

We provide individual parts for your own assembly:

  • Tube bundles - any material (carbon, stainless, nickel alloy, copper alloy, finned tubes)
  • Heat exchanger tubes - cut-to-length, with or without end preparation
  • Fin tubes - extruded or wrapped fins for air coolers or waste heat recovery
  • Tubesheets - drilled, grooved, ready for tube expansion
  • Baffles & tie rods - machined to your exact pattern
Typical Applications
  • Power plants: Generator air cooler bundles, lube oil cooler bundles
  • Petrochemical refineries: Crude preheat exchanger bundles, gas cooler bundles
  • Compressor stations: Intercooler and aftercooler bundles
  • HVAC: Steam-to-water converter bundles, condenser bundles
  • Marine (closed loop): Central cooler bundles (freshwater side)
Request a Quotation - With or Without Drawing

Send your old bundle drawing, field sketch, or heat exchanger model number to jimmy@steelseamlesspipe.com. We will:

  • Review dimensions, tube count, and baffle layout
  • Propose equivalent or upgraded materials
  • Provide firm price and delivery schedule
  • Optionally supply individual components like fin tubes or tubesheets
