Carbon Steel Forged Socket weld, Threaded Fittings, Carbon Steel Flange
Carbon Steel Pipe Fittings are integral components in piping systems, designed to connect, change direction, reduce size, or terminate the flow of fluids or gases. Renowned for strength, durability, and cost-effectiveness, these fittings are widely used in industries such as oil and gas, petrochemical, power generation, construction, and shipbuilding. Available in various grades like ASTM A234 WPB, WPC, and WP11, they offer excellent performance under high-pressure and high-temperature conditions. Carbon steel fittings come in diverse types, including elbows, tees, reducers, caps, and flanges, with options for seamless and welded construction. Their adaptability to different applications and compliance with international standards ensure their reliability in critical operations.
Carbon Steel Flange is a key component in piping systems, designed to connect pipes, valves, pumps, and other equipment to form a secure, durable joint. Made from high-quality carbon steel, these flanges offer excellent mechanical strength, toughness, and resistance to wear, making them ideal for high-pressure and high-temperature applications. carbon steel flanges are valued for their reliability and cost-effectiveness. They are available in various types, including weld neck, slip-on, blind, threaded, and lap joint, to suit different piping configurations. Manufactured to meet global standards like ASME, ASTM, and DIN, carbon steel flanges ensure compatibility, durability, and superior performance in demanding environments.

Carbon steel flanges are used to connect pipes, valves, pumps, and other equipment in a piping system. They create a secure, leak-proof connection between components and are often used in high-pressure and high-temperature systems.
Pipe fittings are used to connect or redirect pipes in a system, while flanges are used to connect piping to valves, pumps, or other piping sections. Fittings typically provide directional changes, while flanges ensure secure connections at system joints.
Common grades for carbon steel fittings and flanges include ASTM A105 (for flanges), ASTM A234 WPB (for fittings), and ASTM A350 LF2 (for low-temperature applications). These grades provide a balance of strength, toughness, and corrosion resistance.
