ASME SA179 Carbon Steel Boiler Tube For Pressure Vessel

ASME SA179 Carbon Steel Boiler Tube For Pressure Vessel

ASME SA179 is a specification under the ASME Boiler and Pressure Vessel Code that covers seamless cold-drawn low-carbon steel tubes designed for heat exchangers, condensers, and similar heat transfer applications. These tubes are widely used in industries such as power generation, petrochemical, and oil refining due to their excellent heat transfer properties and mechanical performance.

Chemical Composition:

• Carbon: 0.06–0.15%
• Manganese: 0.27–0.63%
• Phosphorus: ≤ 0.035%
• Sulfur: ≤ 0.035%
• Silicon: 0.10–0.35%

Mechanical Properties:

• Tensile Strength: 45,000–70,000 psi (310–480 MPa).
• Yield Strength: 25,000 psi (172 MPa).
• Elongation: Minimum of 30% in 8 inches (200 mm) of gauge length.
• Hardness: Relatively low, contributing to its good formability and resilience in heat transfer applications.

Key Features:

• Material: Low-carbon steel, providing good ductility and weldability.
• Manufacturing Process: Cold-drawn seamless process, which ensures high dimensional accuracy and a smooth surface finish.
• Heat Transfer Efficiency: Thin wall thickness and excellent thermal conductivity make them ideal for heat exchangers and condensers.
• Compliance: Manufactured in accordance with ASME SA179/ASTM A179 standards, ensuring high-quality and reliable performance.

Dimensional Range

• Outer Diameter (OD): 1/8 inch to 3 inches (3.2 mm to 76.2 mm).
• Wall Thickness: 1.2 mm to 10 mm.
• Length: As per customer requirements (typically up to 12 meters).

Applications:

• Boiler systems.
• Heat exchangers.
• Condensers.
• Superheaters.

Advantages

• High heat transfer efficiency due to thin wall design.
• Excellent surface finish, suitable for critical heat transfer applications.
• High durability and corrosion resistance in high-pressure environments.
• Easy fabrication and welding.
