Extruded seamless steel pipes are produced by heating round steel billets to a certain temperature and then extruding them through multiple passes in an extruder. Extruded seamless steel pipes have the following functions and characteristics:
1. Improving the strength and hardness of seamless steel pipes: Extrusion refines the grain size and creates a denser structure, thereby increasing the strength and hardness of seamless steel pipes and their load-bearing capacity.
2. Improving the surface quality of seamless steel pipes: Extrusion eliminates internal defects, improves surface finish and dimensional accuracy, and makes seamless steel pipes smoother and flatter.
3. Changing the inner and outer diameters of seamless steel pipes: Extrusion effectively controls the inner and outer diameters of seamless steel pipes, achieving precise dimensional requirements and meeting various engineering and manufacturing needs.
4. Saving raw materials: Extrusion increases steel utilization, reduces waste, and saves costs.
5. Improving production efficiency: The production process of extruded seamless steel pipes is relatively simple, resulting in high production efficiency and suitability for large-scale production.
In general, extruded seamless steel pipes can improve the performance and surface quality of seamless steel pipes through extrusion processing, achieve precise size control, save raw materials, and improve production efficiency. They are widely used in petroleum, chemical, machinery, construction, and other fields.
