About Custom Flanges
Below is the typical chemical composition for custom (carbon steel) flanges manufactured to the ASTMA105 specification. Custom flanges in low pressure piping systems are most often made from this grade:
| Element |
ASTMA105 (%wt) |
| Carbon (C) |
0.35 |
| Manganese (Mn) |
0.60 1.05 |
| Phosphorus (P) |
0.035 |
| Sulfur (S) |
0.040 |
| Silicon (Si) |
0.10 0.35 |
| Copper (Cu) |
0.40 |
| Nickel (Ni) |
0.40 |
| Chromium (Cr) |
0.30 |
| Molybdenum (Mo) |
0.12 |
| Vanadium (V) |
0.08 |
| Iron (Fe) |

Key Points:
-
ASTMA105 is the standard for carbon steel forgings used in piping components (flanges, fittings, valves) for ambient and elevated temperature service
-
Trace elements (Cu, Ni, Cr, Mo, V) are strictly limited to ensure weldability and toughness, while the bulk is iron and manganese with controlled carbon for strength and machinability.

FAQ's of Custom Flanges:
Q: How are custom MS flanges typically installed in industrial piping systems?
A: Custom MS flanges are installed by aligning their round bolt holes with those on the pipe ends and securing them with bolts to form a tight, pressure-resistant seal. Compliance with ANSI standards simplifies integration into various industrial systems.
Q: What benefits do A105 grade mild steel flanges offer in industrial applications?
A: A105 grade mild steel flanges provide outstanding strength, durability, and resistance to high pressure, making them suitable for rigorous industrial environments and ensuring longevity with minimal maintenance.
Q: When is it advisable to use custom flanges over standard fittings?
A: Custom flanges are recommended when your application requires specific dimensions, unique pressure requirements, or compatibility with specialized equipment, offering tailored solutions for non-standard industrial installations.
Q: Where are these custom flanges primarily utilized?
A: These flanges are primarily used in industrial sectors where robust and pressure-resistant connections are essential, such as oil & gas pipelines, chemical plants, and power generation facilities.
Q: What is the manufacturing process for custom mild steel flanges?
A: The process involves cutting and shaping A105 mild steel to precise standards, followed by machining, surface finishing (often in black), and rigorous quality checks to ensure compliance with ANSI specifications and pressure ratings.
Q: How can these flanges enhance the safety and reliability of piping systems?
A: Their durable construction and high-pressure resilience (up to 2500 PSI) provide secure, leak-proof joints, reducing the risk of failures and enhancing the overall reliability and safety of critical industrial pipelines.
