ASTM A106 A53 Seamless Steel Pipe 32-630mm Diameter 3-60mm Wall Thickness for Industrial Applications
Carbon seamless steel pipes feature hollow cross-sections and are widely used for transporting fluids like oil, natural gas, water, and certain solid materials. Compared to solid steel sections, these pipes offer superior bending strength with reduced weight, making them an economical choice for structural and mechanical applications including oil drill pipes, construction scaffolding, and bicycle frames.
Seamless steel pipes are manufactured from solid, round steel billets that are pierced through the center with a mandrel. The billet is rolled and stretched through a hollow billet until it meets customer specifications. This process ensures uniform shape and excellent pressure and heat resistance.
Available in diameters ranging from 32mm to 630mm with wall thicknesses from 3mm to 60mm. Standard lengths of 2-16 meters.
Our hot-rolled seamless steel pipes are produced using advanced three-roll mill technology, ensuring high precision wall thickness control and eliminating defects like scratches and ears.
We maintain extensive stock of carbon seamless tubes, alloy seamless tubes, and precision tubes. Our cold-rolled precision bright tubes feature smooth surfaces, uniform wall thickness, and high dimensional accuracy.
Every pipe undergoes rigorous inspection to ensure surface perfection and consistent wall thickness. We utilize both cold drawing and hot rolling processes to meet diverse application requirements.
Suitable for low/medium pressure boilers, high-pressure boilers, shipbuilding, petroleum cracking, fertilizer equipment, and structural applications across multiple industries.
