Carbon Steel Flanges are essential components in industrial piping systems, designed to connect pipes, valves, pumps, and other equipment to form a sealed and robust pipeline. At Grafton Pipe Fittings, we specialize in the manufacturing and global supply of Carbon Steel Flanges conforming to the highest industry standards, including ASTM A105 and UNS K03504. These flanges are widely used in oil and gas, petrochemical, power generation, water treatment, and shipbuilding industries due to their strength, durability, and resistance to high pressure and temperature environments.
Our ASTM A105 Carbon Steel Flanges offer excellent mechanical properties and forgeability. They are manufactured using high-quality raw materials under stringent quality controls to ensure reliability and long service life. The chemical composition of UNS K03504 provides enhanced tensile strength and toughness, making it an ideal choice for pressure systems and high-temperature service. These flanges are available in various types, including slip-on, weld neck, blind, socket weld, lap joint, and threaded flanges, each suited to specific industrial applications.
At Grafton Pipe Fittings, each Carbon Steel Flange is precision-engineered to meet universal standards such as ANSI, ASME B16.5, B16.47, DIN, BS, and EN. Our flanges are rigorously tested to ensure they meet required pressure ratings (Class 150 to Class 2500) and dimensional tolerances. We also provide material test certificates and third-party inspection reports with every supply, ensuring complete transparency and trust.
Grafton Pipe Fittings is committed to providing reliable piping solutions with timely delivery, competitive pricing, and superior customer support. Our in-house machining and heat-treatment capabilities ensure that all flanges are ready for installation with precise dimensions and surface finish. Whether you need standard sizes or custom-fabricated Carbon Steel Flanges, we can deliver solutions that align with your project requirements.
