Model 426 Spiral Welded Pipe

426 national standard spiral welded pipe is a steel pipe with steel as raw material, made by hot rolling or cold drawing process. Among them, the hot rolling process is to heat the billet to a certain temperature and press it into a continuous cylinder through the rolling machine, and then through the cooling and cutting processes to make spiral welded pipe. The cold drawing process is to place the billet on the tube drawing machine, and gradually thin it by rotating and drawing, and finally form a spiral welded pipe. Because the hot rolling process has the advantages of high production efficiency and low cost, the current market mainly uses the hot rolling process to produce 426 national standard spiral welded pipe.

Secondly, the 426 national standard spiral welded pipe has many excellent performance characteristics. For example, its high strength, good toughness, corrosion resistance, easy processing and other characteristics make it widely used in various engineering fields. In addition, 426 national standard spiral welded pipe also has good sealing and pressure capacity, can withstand greater pressure and temperature changes, suitable for high-pressure gas and liquid transportation and other occasions. At the same time, due to its smooth appearance and high surface accuracy, it is also often used in the manufacturing of parts in precision instruments and equipment.
