GB/T 24590 Enhanced Alloy Seamless Tubes for Efficient Heat Exchanger
The GB/T 24590 standard specifies the requirements for enhanced alloy seamless tubes designed for use in efficient heat exchangers. These tubes are engineered to withstand high temperatures and pressures, making them ideal for demanding industrial applications. This article explores the material specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades of these seamless tubes.
Material Specification
GB/T 24590 seamless tubes are manufactured from high-quality alloy steels. These materials are selected for their excellent thermal conductivity, corrosion resistance, and mechanical strength, ensuring optimal performance in heat exchanger applications.
Key Features
- High Thermal Conductivity: Ensures efficient heat transfer.
- Corrosion Resistance: Suitable for use in corrosive environments.
- Mechanical Strength: Capable of withstanding high pressures and temperatures.
- Durability: Long service life with minimal maintenance requirements.
- Versatility: Applicable in various industrial sectors, including chemical, petrochemical, and power generation.
Chemical Composition
The chemical composition of GB/T 24590 seamless tubes is critical to their performance. Below is a typical composition table:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.05 - 0.15 |
| Silicon (Si) | 0.20 - 0.50 |
| Manganese (Mn) | 0.30 - 0.80 |
| Phosphorus (P) | ≤ 0.030 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 0.50 - 1.20 |
| Nickel (Ni) | 0.30 - 0.80 |
| Molybdenum (Mo) | 0.15 - 0.30 |
Mechanical Properties
The mechanical properties of these tubes ensure they can handle the rigorous demands of heat exchanger applications. Below is a table of typical mechanical properties:
| Property | Value |
|---|---|
| Tensile Strength | 450 - 650 MPa |
| Yield Strength | ≥ 240 MPa |
| Elongation | ≥ 20% |
| Hardness | ≤ 200 HB |
Steel Grade
The GB/T 24590 standard includes various steel grades, each tailored for specific applications. Common grades include:
- Grade 1: General-purpose applications with moderate temperature and pressure requirements.
- Grade 2: Enhanced corrosion resistance for more demanding environments.
- Grade 3: High-temperature applications with superior mechanical properties.
Application
GB/T 24590 seamless tubes are widely used in:
- Chemical Processing: For efficient heat transfer in reactors and condensers.
- Petrochemical Industry: In refineries and gas processing plants.
- Power Generation: In boilers and heat recovery steam generators.
- Oil and Gas: For offshore and onshore applications requiring robust performance.
Possible Alternative Grades
While GB/T 24590 tubes are highly effective, alternative grades may be considered based on specific requirements:
- ASTM A213: Suitable for high-temperature service.
- EN 10216-2: Offers similar mechanical properties with different chemical compositions.
- JIS G3462: Japanese standard for alloy steel tubes used in boilers and heat exchangers.
