An extruded seamless steel pipe is a pipe made by heating a round steel billet to a certain temperature and extruding it through multiple passes in an extruder. Extruded seamless steel pipe has the following functions and characteristics:
1. Improve the strength and hardness of the steel pipe: Extrusion processing can refine the grains of the steel pipe and make the structure closer, thereby improving the strength and hardness of the steel pipe and increasing its load-bearing capacity.
2. Improve the surface quality of the steel pipe: Extrusion processing can eliminate internal defects of the steel pipe, improve the surface finish and dimensional accuracy, and make the steel pipe smoother and smoother.
3. Change the inner and outer diameter dimensions of the steel pipe: Extrusion processing can effectively control the inner and outer diameter dimensions of the steel pipe to achieve precise dimensional requirements and is suitable for various engineering and manufacturing needs.
4. Save raw materials: Extrusion processing can increase the utilization rate of steel, reduce waste, and save costs.
5. Improve production efficiency: The production process of extruded seamless steel pipes is relatively simple, has high production efficiency, and is suitable for large-scale production.
In general, extruded seamless steel pipes can improve the performance and surface quality of steel pipes, achieve precise dimensional control, save raw materials, and improve production efficiency through extrusion processing. They are widely used in petroleum, chemical industry, machinery, construction, and other fields.
