Product IntroductionCarbon Seamless Steel Pipe / Tube
Seamless carbon steel pipes are crafted from steel ingots or solid billets, transformed into capillaries through precise perforation, followed by hot-rolling, cold-rolling, or cold-drawing processes. Starting with a round tube blank as the raw material, it's expertly cut into billets approximately one meter long, which are then ushered into a furnace via a conveyor belt for optimal heating. Within the furnace, these billets are heated to an impressive 1200 degrees Celsius, utilizing either hydrogen or acetylene as fuel. Meticulous control of the furnace temperature is paramount for quality assurance. As the round tube blank exits the furnace, it undergoes pressure punching through an efficient conical roller punching machine, well-regarded for its outstanding production efficiency and superior product quality. This method accommodates a wide range of perforation and diameter expansion, adeptly handling various steel grades. Post-perforation, the round tube blank undergoes further transformation by cross-rolling, continuous rolling, or extrusion using a three-roll process.
1. Seamless steel pipe for structure (GBT8162-2008). Primarily utilized in general structural and mechanical frameworks, showcasing the durability and strength of materials like carbon steel, 20, 45 steel; and alloy steels such as Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, among others.
2. Seamless steel pipes for conveying fluids (GBT8163-2008). These pipes excel in transporting fluids across engineering ventures and large-scale equipment, crafted from high-grade materials like 20, Q345, ensuring reliability and performance.
3. Seamless steel pipes for low and medium pressure boilers (GB3087-2008) are ingeniously designed for various configurations of low and medium pressure boiler systems, including superheated steam pipes, boiling water conduits, and locomotive boilers' architectural elements like large and small smoke pipes, and arch bricks. These pipes, made from high-quality carbon structural steel, are available in both hot-rolled and cold-drawn (rolled) varieties, with 10, 20 steel as the representative materials.
