ASTM A105 Blind Flange Element Composition
| Element | Carbon (C) | Silicon (Si) | Manganese (Mn) | Sulfur (S) | Phosphorus (P) | Copper (Cu) | Nickel (Ni) | Molybdenum (Mo) | Vanadium (V) | Chromium (Cr) |
| Content Range (%) | ≤ 0.35 | ≤ 0.35 | 0.60 – 1.05 | ≤ 0.050 | ≤ 0.040 | ≤ 0.4 | ≤ 0.4 | ≤ 0.12 | ≤ 0.08 | ≤ 0.3 |
A105: Carbon steel material conforming to ASTM A105 standard, suitable for high-temperature and high-pressure environments.
Chemical composition: The main components are carbon (C), manganese (Mn), silicon (Si), etc., and the specific components meet the ASTM A105 standard.
Advantages of A105 Blind Flange
- High strength: Carbon steel material provides good strength and durability.
- Corrosion resistance: Although the corrosion resistance of carbon steel is not as good as stainless steel, it performs well in many non-corrosive or slightly corrosive environments.
- Cost-effective: Compared to other high-grade materials such as stainless steel or alloy steel, A105 blind flanges are less expensive and suitable for large-scale applications.
- Easy to install and maintain: The simple design allows for easy installation and disassembly, facilitating maintenance and repairs.
Application of A105 Blind Flange
Oil and gas: used for high-pressure pipelines.
Chemical industry: used for pipelines carrying corrosive media.
Electric power: used for high-temperature and high-pressure steam pipelines.
Shipbuilding: used for ship pipeline systems.
