Q345B Seamless Steel Pipe
According to the GB/T 8162-2018 standard, it is divided into three types based on manufacturing processes: hot rolling, cold drawing, and hot expansion. Hot rolled pipes are suitable for specifications above Φ 325mm, with a wall thickness tolerance of ± 10% for cold drawing processes and a diameter expansion rate of no more than 40% for hot expansion processes.
The alloy composition of the steel pipe contains niobium, vanadium, and titanium elements, with a tensile strength of 470-630MPa and an elongation rate of ≥ 21%. The production process adopts three roll oblique rolling forming technology, with a rolling speed of 1200 revolutions per minute. The cold drawing process can reduce the diameter of 108mm steel pipes to 89mm, and the single pass deformation exceeds 30%. Widely used in oil and gas pipelines (pressure up to 15MPa), superheated steam pipes for power plant boilers, and hydraulic cylinders for engineering machinery (wall thickness 20-50mm)
Our company's products have obtained ISO9001 certification, ensuring product quality
