Yuhong Group Co., Ltd. specializes in the design and supply of ASME-coded heat exchange equipment, pressure vessels, and air coolers for demanding industrial services. Our comprehensive product portfolio includes complete shell-and-tube heat exchangers, replacement tube bundles, U-tubes, heat exchanger tubes, finned tubes, and all supporting components including tube sheets, baffles, channels, and flanges. With extensive experience in refinery and petrochemical applications, we provide engineered solutions backed by ASME U-Stamp certification and full material traceability.
Product Overview
The ASME SA179 Tube Bundle is a pre-assembled, removable core designed for installation into shell-and-tube heat exchangers, condensers, and similar heat transfer apparatus. Manufactured in full compliance with ASME BPVC Section VIII, Division 1 and TEMA standards, this bundle utilizes seamless cold-drawn low-carbon steel tubes for efficient thermal conductivity and structural integrity. The design supports continuous operation in non-corrosive and mildly corrosive services at temperatures up to 400°C and pressures up to 206.8 bar (3000 psi).

Inspection Objective
Hydrostatic Test
ASME Section VIII UG-99
Verify tube-to-tubesheet joint tightness and pressure boundary integrity
Mechanical Testing
Tensile, flattening, flaring, expanding tests per SA-450
Petrochemical Processing: Heat exchange equipment for hydrocarbon and steam services
Power Generation: Steam turbine condensers, district heating water heaters, lube oil coolers
General Industrial: Compressor aftercoolers, heat recovery systems, hydraulic oil cooling
Service Limitation: SA179 carbon steel tube bundles are not recommended for direct service in acidic media (high H₂S content without inhibitors) or aggressive chlorides unless additional protective coating or cladding is applied.
Engineering Advantages and Customization Services
ASME U-Stamp Compliance: Equipment fabricated with ASME U-Stamp certification is accepted for installation in the United States and Canada without additional jurisdictional inspection requirements. The certification remains valid for three years with mandatory AIA audits.
Stress-Relieved Tube Construction: After the final cold-drawing pass, SA179 tubes undergo heat treatment at a minimum temperature of 650°C (1200°F) to eliminate residual stresses from the manufacturing process, ensuring dimensional stability and consistent mechanical properties.
Full Customization: Each tube bundle is engineered to customer-provided specifications, including:
Tube count, layout, and pitch
Baffle spacing and cut percentage
Tube sheet thickness and bolt hole configuration
U-bend radius, straight leg length, and tube pitch for U-tube bundles
Post-bending heat treatment and additional NDE requirements
Material Documentation: A complete documentation package is available, including:
Material Test Certificates (MTC) with heat number traceability
Chemical and mechanical test reports
Dimensional inspection reports
Hydrostatic and NDE test reports
Heat treatment records
Third-party inspection documents (when required)
Frequently Asked Questions
What is the standard outside diameter range for ASME SA179 tubes in a tube bundle?
ASME SA-179/SA-179M covers seamless tubes 1/8 to 3 inches [3.2 to 76.2 mm] in outside diameter. Common stock sizes include 19.05 mm × 1.65 mm, 25.4 mm × 2.11 mm, and 38.1 mm × 3.05 mm, though sizes can be customized to meet specific design requirements.
Can a tube bundle be replaced without replacing the entire heat exchanger?
Yes. Tube bundles are designed as removable, replaceable components. When the existing bundle reaches its service life due to corrosion, erosion, or thermal fatigue, a replacement bundle manufactured to the original dimensions and specifications can be installed, extending the overall equipment service life.
What is the difference between ASTM A179 and ASME SA179 for heat exchanger tubes?
ASTM A179 and ASME SA179 share the same material and dimensional requirements. The ASME SA179 designation indicates that the material is manufactured to ASME BPVC Section II, Part A specifications and is qualified for use in ASME-code construction projects. For ASME-stamped equipment, SA179 is the required designation.
