Product Description

ASTM A178 Electric-Resistance-Welded Tube Carbon Steel Tube

ASTM A178 is a resistance-welded carbon steel tube material specifically designed for boiler superheater tubes. Its manufacturing process and performance indicators comply with ASTM International standards, ensuring structural integrity and heat transfer efficiency under the high-temperature and high-pressure operating conditions of boilers.

Material and Specifications

The base material of this product is carbon steel, manufactured using the resistance welding process. This process melts the edges of the steel tube using heat generated by electric current and joins them under pressure, offering high production efficiency and good cost-effectiveness. Its specifications cover a wide range, with outer diameters typically from 1/2 inch (approximately 12.7 mm) to 4 inches (approximately 101.6 mm). The wall thickness is selected within the range specified by the standard according to the pressure and temperature requirements of the boiler design, to adapt to superheater systems of different power levels.

Chemical Composition

The chemical composition of ASTM A178 carbon steel must meet the requirements in the table below. The content of key elements such as carbon and manganese is strictly controlled to ensure the material's oxidation resistance and creep resistance at high temperatures.

Element	Content Range (%)
Carbon (C)	0.06 - 0.18
Manganese (Mn)	0.30 - 0.60
Phosphorus (P)	≤ 0.035
Sulfur (S)	≤ 0.035
Silicon (Si)	0.10 - 0.35
Copper (Cu)	≤ 0.08

Mechanical Properties

At room temperature, the mechanical properties of ASTM A178 steel tubes must meet the specifications in the table below, ensuring they can withstand temperature fluctuations and pressure loads during boiler startup, operation, and shutdown.

Mechanical Property	Requirement
Tensile Strength	≥ 330 MPa (48,000 psi)
Yield Strength	≥ 180 MPa (26,000 psi)
Elongation in 2 inches (50 mm)	≥ 28%

Applications

The core application of ASTM A178 steel tubes is as boiler superheater tubes, and they can also be used for heated surface components such as boiler reheater tubes. It is widely used in energy conversion equipment like thermal power plants, industrial boilers, and waste heat boilers to convey high-temperature and high-pressure steam. The welds formed by the resistance welding process have good density and strength, enabling adaptation to the operating conditions of high steam temperature and fast flow rate in superheaters. The carbon steel base ensures the material's thermal conductivity and cost-effectiveness, meeting the reliability requirements of boilers during long-term continuous operation.
