Kabby Flanges is a well-respected manufacturer and supplier located in Abuja, Nigeria, specializing in top-notch Carbon Steel Weldneck Flanges. These flanges are celebrated for their remarkable strength, durability, and precision engineering. They’re crafted to create a secure, leak-proof connection in piping systems that operate under high pressure and temperature. With state-of-the-art manufacturing facilities and rigorous quality control measures, Kabby Flanges guarantees reliable products that adhere to international standards. Their Carbon Steel Weldneck Flanges are a go-to choice in the oil and gas, petrochemical, and power generation sectors, thanks to their robustness and long-lasting performance.
These flanges are primarily made from carbon, manganese, silicon, and small amounts of sulfur and phosphorus. The carbon boosts tensile strength and hardness, while manganese enhances toughness. With a tensile strength ranging from 485 to 620 MPa and a yield strength of about 250 MPa, they offer excellent load-bearing capabilities. Plus, they resist deformation under pressure, boast good weldability, and are built to last, making them perfect for high-stress and high-temperature industrial applications.
