Steel Flange Adaptor
Steel flange adaptor is a specialized fitting used in piping systems to connect pipes or other components that have different end types, such as a plain end or a grooved end, to a flanged end. These adaptors are made of steel, which provides strength, durability, and resistance to high pressures and temperatures.
Compared to cast iron flange adaptors, carbon steel flange adaptors can withstand higher pressures such as PN40, PN63 or PN100 which is impossible for cast iron flange adaptor to afford.

What is the difference for steel flange adaptor and iron flange adaptor ?
The primary differences between a steel flange adaptor and an iron flange adaptor are based on the materials they are made from, which affect their properties and applications. Here are the key differences:
- Material Composition:
Steel Flange Adaptor: Made from various grades of steel, typically carbon steel or stainless steel.
Iron Flange Adaptor: Made from cast iron or ductile iron.
- Strength and Durability:
Steel Flange Adaptor: Generally stronger and more durable than iron. Steel has better tensile strength, making it suitable for high-pressure applications.
Iron Flange Adaptor: Cast iron is brittle and can break under high stress, while ductile iron is more flexible and stronger than cast iron but still generally not as strong as steel.
- Corrosion Resistance:
Steel Flange Adaptor: Stainless steel flange adaptors offer excellent corrosion resistance, especially in harsh environments. Carbon steel flange adaptors may require protective coatings to resist corrosion.
Iron Flange Adaptor: Cast iron has limited corrosion resistance and can rust without proper coatings. Ductile iron has better corrosion resistance than cast iron but still require protective measures.
- Weight:
Steel Flange Adaptor: Generally lighter than iron for the same dimensions, which can make installation easier and reduce transportation costs.
Iron Flange Adaptor: Heavier, which might make handling and installation more difficult.
- Cost:
Steel Flange Adaptor: Typically more expensive due to the higher cost of steel and the processes involved in manufacturing.
Iron Flange Adaptor: Generally less expensive than steel, making it a cost-effective option for many applications.
- Applications:
Steel Flange Adaptor: Used in applications requiring high strength, durability, and corrosion resistance, such as in chemical plants, oil and gas pipelines, and marine environments.
Iron Flange Adaptor: Commonly used in water supply systems, sewage systems, and other applications where high strength is not the primary requirement.
- Fabrication:
Steel Flange Adaptor: Can be fabricated into complex shapes and sizes with precision, making them suitable for custom applications.
Iron Flange Adaptor: Typically cast, which can limit the complexity of shapes and sizes that can be produced.
These differences determine the suitability of each type of flange adaptor for specific applications and environments.
