Product Description

ASME SA179 U Bend Tube SA266 Grade 2 Tubesheet Tube Bundle for Heat Exchangers

 

Yuhong Holding Group Co., Ltd is a world-renowned manufacturer and supplier of industrial equipment, specializing in heat exchangers, fired heaters, air coolers, and related components. With decades of experience and a commitment to quality, we provide high-performance products tailored to the needs of various industries. One of our premier offerings is the ASME SA179 U Bend Tube SA266 Grade 2 Tubesheet Tube Bundle, designed for use in heat exchangers. These tube bundles are manufactured with precision and undergo rigorous testing to ensure maximum reliability in demanding applications.


1. ASME SA179 Chemical Composition and Mechanical Properties

 

ASME SA179 is a high-quality carbon steel widely used for heat exchanger and condenser tubing due to its excellent thermal conductivity, durability, and corrosion resistance. Its low carbon content ensures superior ductility, making it ideal for U-bending and other manufacturing processes.

Chemical Composition of SA179

Element Composition (%)
Carbon (C) ≤ 0.06
Manganese (Mn) 0.27–0.63
Phosphorus (P) ≤ 0.035
Sulfur (S) ≤ 0.035

Mechanical Properties of SA179

Property Value
Tensile Strength ≥ 325 MPa (47,000 psi)
Yield Strength ≥ 180 MPa (26,000 psi)
Elongation ≥ 35%
Hardness ≤ 72 HRB

These properties, combined with the material's excellent heat transfer capabilities, make SA179 a preferred choice for heat exchanger tubing.


2. Common Outer Diameter (OD) and Wall Thickness (WT) of Heat Exchanger Tubes

 

Heat exchanger tubes are manufactured in a variety of sizes to meet specific application requirements. Below is a table showcasing the most common tube dimensions for SA179 U Bend Tubes:

Outer Diameter (OD) (mm/inch) Wall Thickness (WT) (mm/inch)
12.7 mm (1/2") 1.24 mm (0.049")
15.88 mm (5/8") 1.65 mm (0.065")
19.05 mm (3/4") 1.65 mm (0.065")
25.4 mm (1") 2.11 mm (0.083")
38.1 mm (1-1/2") 2.77 mm (0.109")

These dimensions ensure flexibility in design while maintaining optimal thermal performance.


3. Testing Requirements for Heat Exchanger Tube Bundles

 

To guarantee the quality and performance of our ASME SA179 U Bend Tubes with SA266 Grade 2 Tubesheets, we perform comprehensive testing on each product. At Yuhong Holding Group, we adhere to stringent industry standards to ensure our products perform flawlessly under the most challenging conditions.

Key Tests Performed

  1. Hydrostatic Testing: Verifies the tubes' ability to withstand high pressures without leakage.
  2. Penetrant Testing (PT): Ensures the surface of the U bend tubes and welds is free from cracks, pinholes, or other defects.
  3. Eddy Current Testing (ECT): Detects any material discontinuities within the tubes.
  4. Ultrasonic Testing (UT): Ensures the integrity of the tube material and welds.
  5. Dimensional Inspection: Confirms the accuracy of U bends, tube lengths, and wall thickness.
  6. Hardness Testing: Ensures the mechanical properties meet ASME SA179 specifications.
  7. Visual Inspection: Detects any visible defects or irregularities on the surface of the tubes and tubesheets.

Each tube bundle is supplied with a complete set of test certificates and inspection reports, ensuring full traceability and compliance with customer requirements.


4. Applications of SA179 U Bend Tube Bundles

 

The ASME SA179 U Bend Tube Bundles with SA266 Grade 2 Tubesheets are widely used in various industries where efficient heat transfer is critical. Key application areas include:

  • Petrochemical Industry: For heat exchangers in refineries and chemical plants.
  • Power Generation: Used in condensers, feedwater heaters, and other heat exchangers in power plants.
  • Oil and Gas Industry: For offshore and onshore processing systems requiring high-performance heat exchangers.
  • HVAC Systems: In refrigeration and air conditioning systems for efficient heat exchange.
  • Food and Beverage Industry: For sanitary heat exchangers used in pasteurization and processing.

These products are valued for their durability, performance, and ability to withstand harsh operating environments.
