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.
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.
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 |
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% |
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.
ASTM A178 GrA tubes are primarily used in:
These tubes are essential in industries such as power generation, petrochemical, and chemical processing, where efficient heat transfer is critical.
While ASTM A178 GrA is a popular choice, there are alternative grades that may be considered based on specific application requirements:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
