What is an MS Flange Adaptor?

MS (Mild Steel) flange adaptors are mechanical fittings made from carbon steel (Q235/A3) with a fixed flange on one end and a socket/spigot on the other. They enable quick, weld-free connection of plain-end pipes to flanged components, ideal for water, irrigation, and low-pressure industrial systems.

Coated with fusion-bonded epoxy (blue/black) for corrosion protection; compatible with steel, DI, PVC, and PE pipes (with inserts for PE).

Key Features & Advantages

  • Cost-Effective: Mild steel construction significantly cheaper than stainless or DI alternatives.
  • Corrosion Protection: Epoxy coating (250-400 μm) for extended outdoor/indoor life.
  • Easy Installation: No welding required; quick bolt-up assembly.
  • Flexibility & Tolerance: Accommodates misalignment, axial movement, and pipe OD variations.
  • Reliable Sealing: EPDM gasket ensures leak-tight performance up to PN16.

Advantages

At Sunny Steel, we are guided by three fundamental core values that shape our approach and drive our success.

1. Versatility

Flange adapters allow for the connection of different types of flanges, such as ANSI, DIN, or JIS flanges, enabling compatibility between different flange standards. This versatility makes it easier to connect and integrate various components and piping systems.

2. Flexibility

Flange adapters provide flexibility in adapting flanged components to non-flanged equipment or systems. They allow for the connection of flanged pipes to valves, pumps, or other equipment that may not have flanged ends, eliminating the need for extensive modifications or welding.

3. Easy installation and removal

Flange adapters simplify the installation and removal process compared to welding or other permanent joining methods. They can be easily aligned and bolted together, reducing downtime during maintenance or repairs.

4. Leak-proof connections

The use of gaskets or sealing elements with flange adapters ensures a tight and leak-proof connection between flanged components. This helps prevent fluid or gas leakage, promoting safety and efficiency in the piping system.

5. Cost-effective

Flange adapters can be a cost-effective solution compared to welding or using custom-made flanged components. They eliminate the need for complex fabrication, reduce labor costs, and enable faster installation and disassembly.

6. Durability and reliability

Flange adapters are typically made from sturdy and corrosion-resistant materials, ensuring long-lasting performance and reliability in demanding environments. They can withstand high pressures, temperature variations, and chemical exposures.

7. Modular design

Flange adapters allow for modular construction and easy reconfiguration of piping systems. They can be easily disconnected and reused, offering flexibility in system design, modification, or expansion.
