ASTM A178 GrA Heat Exchanger Tube ERW Carbon Welded Steel Tube For Heat Exchanger
Material
ASTM A178 Grade A tubes are electric-resistance-welded (ERW) carbon steel tubes specifically designed for use in heat exchangers, condensers, and similar heat transfer apparatus. These tubes are known for their durability, efficiency, and cost-effectiveness, making them a popular choice in various industrial applications.
Specification
ASTM A178 GrA tubes are manufactured to meet the standards set by the American Society for Testing and Materials (ASTM). These tubes are typically used in high-temperature environments and are designed to withstand the rigors of heat exchange processes. The specification covers the minimum requirements for the material, including its chemical composition, mechanical properties, and dimensions.
Key Features
- High Durability: Designed to withstand high temperatures and pressures.
- Corrosion Resistance: Offers good resistance to corrosion, ensuring longevity.
- Cost-Effective: Provides an economical solution for heat exchanger applications.
- Versatile: Suitable for a wide range of industrial applications.
- Consistent Quality: Manufactured to meet stringent ASTM standards.
Chemical Composition
The chemical composition of ASTM A178 GrA tubes is crucial for ensuring their performance in heat exchanger applications. Below is a table presenting the typical chemical composition:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.06 - 0.18 |
| Manganese (Mn) | 0.27 - 0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
Mechanical Properties
The mechanical properties of ASTM A178 GrA tubes determine their ability to withstand physical forces and high temperatures. The table below outlines these properties:
| Property | Value |
|---|---|
| Tensile Strength | ≥ 325 MPa (47,000 psi) |
| Yield Strength | ≥ 180 MPa (26,000 psi) |
| Elongation | ≥ 35% |
Steel Grade
ASTM A178 GrA is a specific grade within the ASTM A178 standard, which includes several other grades. Grade A is characterized by its specific chemical composition and mechanical properties, making it suitable for heat exchanger applications.
Application
ASTM A178 GrA tubes are primarily used in:
- Heat exchangers
- Condensers
- Boilers
- Superheaters
- Economizers
