GB/T 28413 specifies the requirements for Electric Resistance Welded (ERW) steel pipes, primarily used in heat exchangers. They are made from high-quality carbon steel, which provides excellent thermal conductivity and structural stability, making them ideal for the rigorous demands of heat exchanger applications.
| Element | Minimum % | Maximum % |
|---|---|---|
| Carbon (C) | - | 0.20 |
| Silicon (Si) | - | 0.35 |
| Manganese (Mn) | 0.30 | 1.20 |
| Phosphorus (P) | - | 0.040 |
| Sulfur (S) | - | 0.040 |
Note: The exact chemical composition may vary slightly depending on specific grades and customer requirements.
| Property | Value |
|---|---|
| Tensile Strength (MPa) | 340 to 490 |
| Yield Strength (MPa) | ≥ 205 |
| Elongation (%) | ≥ 24 |
| Impact Energy (J) | ≥ 27 at 20°C |
The mechanical properties are indicative and may be subjected to quality tests.
Common steel grades for GB/T 28413 include Q195, Q215, Q235, Q345, tailored to meet varying mechanical and chemical demands. These grades provide different levels of strength and durability while maintaining compliance with industry standards.
ERW steel pipes under GB/T 28413 are widely used in:
Their adaptability makes them a preferred choice in sectors such as power generation, petrochemical, and manufacturing.
While GB/T 28413 covers specific requirements, alternative standards or grades can be used provided they meet performance criteria. Possible alternatives include:
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.
