Hot rolled seamless steel pipes are widely used in various industries due to their high strength, durability, and resistance to high pressure. In this article, we will explore the GB 6479 standard for hot rolled seamless steel pipes used in high-pressure fertilizer equipment. We will discuss the material, specification, chemical composition, mechanical properties, steel grade, and application of these pipes.
The material used for manufacturing hot rolled seamless steel pipes according to GB 6479 standard is carbon steel. Carbon steel offers excellent mechanical properties and is suitable for high-pressure applications.
The specification of hot rolled seamless steel pipes under GB 6479 standard includes the following parameters:
The chemical composition of hot rolled seamless steel pipes must conform to the requirements specified in GB 6479. The following table presents the typical chemical composition of these pipes:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.07-0.13 |
| Silicon (Si) | 0.17-0.37 |
| Manganese (Mn) | 0.35-0.65 |
| Phosphorus (P) | ≤0.030 |
| Sulfur (S) | ≤0.025 |
| Chromium (Cr) | ≤0.25 |
| Nickel (Ni) | ≤0.25 |
| Copper (Cu) | ≤0.25 |
| Molybdenum (Mo) | ≤0.10 |
The hot rolled seamless steel pipes under GB 6479 standard exhibit excellent mechanical properties to withstand high pressure and ensure reliable performance. The following table outlines the typical mechanical properties of these pipes:
| Property | Value |
|---|---|
| Tensile Strength | ≥600 MPa |
| Yield Strength | ≥320 MPa |
| Elongation | ≥20% |
| Hardness (HB) | ≤197 |
| Impact Toughness | ≥27 J/cm² (at 20°C) |
The steel grade specified in GB 6479 for hot rolled seamless steel pipes is 20G. This grade represents a low carbon steel with excellent weldability, high toughness, and good mechanical properties.
Hot rolled seamless steel pipes conforming to GB 6479 standard and made from 20G steel grade are primarily used in high-pressure fertilizer equipment. These pipes are commonly employed in the manufacturing of urea reactors, high-pressure piping systems, and other components involved in fertilizer production. The pipes' superior strength, chemical resistance, and reliability make them ideal for handling the demanding conditions encountered in fertilizer manufacturing processes.
