The pipes conform to the GB/T 30059 standard and are manufactured using corrosion-resistant alloys designed to withstand harsh environments, particularly in heat exchanger systems.
The chemical composition of the alloys used in these pipes is detailed below:
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 50–55 |
| Chromium (Cr) | 18–21 |
| Iron (Fe) | Balance |
| Molybdenum (Mo) | 8–10 |
| Copper (Cu) | ≤1.00 |
| Carbon (C) | ≤0.10 |
The mechanical properties of these pipes are crucial for their performance. Below is a table summarizing the key mechanical properties:
| Property | Value |
|---|---|
| Tensile Strength | ≥620 MPa |
| Yield Strength | ≥275 MPa |
| Elongation | ≥35% |
| Hardness (HB) | ≤180 |
Other standards and steel grades that are similar to GB/T 30059 include:
These standards and grades offer comparable or enhanced properties for corrosion-resistant alloy pipes.
These pipes are primarily used in:
Their ability to resist corrosion and maintain performance under demanding conditions makes them ideal for these applications.
