The material used for the seamless steel tube, specifically designed for heat exchangers, is carbon steel. This type of steel is known for its excellent strength and durability, making it suitable for high-pressure and high-temperature applications.
The seamless steel tube is manufactured according to the ASTM A556 standard. This specification provides guidelines for the production of seamless cold-drawn carbon steel tubes for use in heat exchangers. It ensures the tubes meet the necessary requirements for chemical composition, mechanical properties, and dimensional accuracy.
The chemical composition of the seamless steel tube is as follows:
| Element | Composition (%) |
| Carbon | 0.17 max |
| Manganese | 0.37-0.64 |
| Phosphorus | 0.035 max |
| Sulfur | 0.035 max |
| Silicon | 0.10-0.35 |
The seamless steel tube exhibits excellent mechanical properties, allowing it to withstand the demanding conditions of heat exchangers. The following table outlines the typical mechanical properties of ASTM A556 carbon steel tubes:
| Property | Value |
| Tensile Strength | 325 MPa min |
| Yield Strength | 180 MPa min |
| Elongation | 35% min |
| Hardness | HRB 80-90 |
In addition to its chemical and mechanical properties, the seamless steel tube possesses certain physical characteristics. These properties include:
| Property | Value |
| Density | 7.85 g/cm³ |
| Melting Point | 1420-1460°C |
| Thermal Conductivity | 51.9 W/m·K |
| Electrical Conductivity | 1.45 MS/m |
| Modulus of Elasticity | 200 GPa |
The seamless steel tube is produced using a cold-drawn process, which involves pulling the tube through a die to achieve the desired dimensions. This manufacturing technique ensures the tube's excellent surface finish, dimensional accuracy, and enhanced mechanical properties. The cold-drawn process also enhances the tube's resistance to corrosion and provides better tolerance control.
The ASTM A556 seamless steel tube is specifically designed for use in heat exchangers. Heat exchangers are widely used in various industries, including power generation, chemical processing, oil and gas, and HVAC systems. The seamless carbon steel tube's high strength and resistance to high temperatures make it ideal for transferring heat between two fluids while maintaining structural integrity.
