Product Description
The GB/T 20409 standard specifies the use of internally threaded seamless multi-rifled steel pipes for high-pressure boilers. These pipes are made from specific materials that meet the requirements outlined in the standard. The main material used for these pipes is high-quality carbon structural steel.
The specification of GB/T 20409 Internally Threaded Seamless Multi-Rifled Steel Pipes for High-Pressure Boilers is as follows:
These specifications ensure that the pipes are suitable for use in high-pressure boiler applications, providing durability and reliability.
The chemical composition of the GB/T 20409 Internally Threaded Seamless Multi-Rifled Steel Pipes is as follows:
| Element | Composition (% by weight) |
|---|---|
| Carbon (C) | 0.27 - 0.35 |
| Silicon (Si) | 0.17 - 0.37 |
| Manganese (Mn) | 0.70 - 1.00 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
These specifications ensure the pipes have the necessary chemical properties for high-pressure boiler applications.
The mechanical properties of the GB/T 20409 Internally Threaded Seamless Multi-Rifled Steel Pipes are as follows:
| Property | Value |
|---|---|
| Tensile Strength | ≥ 410 MPa |
| Yield Strength | ≥ 245 MPa |
| Elongation | ≥ 25% |
| Impact Toughness | ≥ 34 J/cm² |
| Hardness (HB) | ≤ 179 HB |
These mechanical properties ensure that the pipes can withstand high-pressure environments and provide sufficient strength and toughness.
The GB/T 20409 standard defines the following steel grade for the internally threaded seamless multi-rifled steel pipes: 20G.
The GB/T 20409 Internally Threaded Seamless Multi-Rifled Steel Pipes are primarily used in high-pressure boiler systems. These pipes are designed to withstand high temperatures and pressure conditions, making them suitable for use in various industries including power generation, chemical plants, and heating systems.
By utilizing the internally threaded design, these pipes offer enhanced heat transfer capabilities, improving the overall efficiency of high-pressure boilers. The excellent reliability and durability of these pipes ensure safe and efficient operation in demanding boiler applications.
