ASTM A105 Mild Steel Flange

A mild steel flange is a type of connector used in piping systems to join sections of pipes or valves together. It is typically made from mild steel, which is a type of carbon steel known for its relatively low carbon content and easy formability.

Mild Steel Flanges come in various shapes and sizes, but they generally consist of a flat, circular disk with evenly spaced holes for bolts to secure it to another flange or to the end of a pipe. The flange's flat surface allows it to be bolted securely against another flat surface, creating a tight seal to prevent leaks in the piping system.

Mild Steel flanges are commonly used in a wide range of industries, including construction, oil and gas, petrochemical, water treatment, and more. They are preferred for their affordability, ease of machining, and suitability for many applications where moderate strength and corrosion resistance are sufficient.

Mild steel flanges are preferred for their affordability, ease of machining, and suitability for many applications where moderate strength and corrosion resistance are sufficient. They also offer good weldability and ductility.
Mild steel flanges are widely used in industries such as construction, oil and gas, petrochemical, water treatment, HVAC, and plumbing for connecting piping systems, valves, and equipment.
Yes, mild steel flanges can be used with a variety of piping materials, including mild steel pipes, stainless steel pipes, and non-metallic pipes such as PVC or CPVC. Compatibility with the piping material and the application's requirements should be considered when selecting flanges.
