Mild Steel Flanges are used extensively in industries such as oil and gas, construction, water treatment, shipbuilding, and power generation. They are essential components in piping systems, serving to connect pipes, valves, pumps, and other equipment securely and efficiently. Their robust structure and weldable nature allow for custom fabrication to meet specific system requirements. These flanges also find use in HVAC systems, chemical plants, and manufacturing setups, where they provide reliable sealing and support in fluid handling and structural frameworks, particularly in low to moderate pressure environments.
Mild steel flanges are widely employed in piping systems for piping fittings, valves, pumps, and other equipment. They provide a strong, resilient, and low-cost solution for creating leak-proof assemblies. These flanges are suitable for low-pressure applications and are commonly used in water treatment, construction, HVAC systems, and automotive sectors. Mild steel flanges possess average pressure and temperature ratings, therefore are suitable for general use in applications where corrosion resistance is not much. They are also used because of their ease of assembly and maintenance in pipes.
Samuel Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products. Our extensive product range includes Pipes, Tubes, Flanges, Pipe Fittings, Forged Fittings, Sheets and Plates, catering to various industries in Abuja, Nigeria.
