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
