In recent years, automotive manufacturers are under increasing pressure to improve fuel efficiency as more attention is paid to environmental issues. Stricter and more stringent regulations are creating technical challenges for industrial production and material processing. Among these trends are lower emissions, lighter bodies and longer part life.
Do you know the ways to make spiral steel pipes last longer?
Advances in materials processing technology present good opportunities for the production of spiral steel pipes. Specifically, manufacturers are being asked to produce such parts that are lighter in weight, yet still have corrosion-resistant properties and meet strength requirements. In addition, the space limitations of the body emphasize the importance of formability. Typical applications include exhaust pipes, fuel lines, nozzles and other components.
In spiral steel pipe, flat steel strips are formed first, followed by circular strips. Once formed, the joints of the spiral pipe are welded together. This welding affects the formability of the part. Therefore, it is very important to choose the right welding process to obtain a weld shape that can meet the strict testing requirements of the manufacturing industry. Undoubtedly, tungsten gas shielded welding (GTAW), high frequency (HF) welding and laser welding have been used in the manufacture of stainless steel tubes.
