Production process of welded pipes
1. Material preparation: The initial stage involves selecting premium materials such as wide steel strips, hot-rolled steel strips, and cold-rolled steel strips, ensuring the foundation for exceptional quality. These materials undergo precise cutting, leveling, and thorough cleaning, meticulously tailored to meet stringent process requirements for superior finished welded pipes.
2. Curling forming: The expertly treated steel strip is elegantly molded into a compact diameter tube, shaped flawlessly by advanced curling machinery.
3. Welding process: Utilizing state-of-the-art high frequency induction welding or resistance welding technology, the curled tube is seamlessly transformed into a robust long welded pipe.
4. Steel annealing: The annealing process significantly softens the steel pipe, effectively minimizing hardness while alleviating stress levels and internal tension in the finished welded pipe.
5. Size cutting: The elongated welded pipe is meticulously cut to specified lengths, adhering strictly to process requirements for precise dimensions.
6. Fine repair process: The cut welded pipe undergoes a refined repair process, incorporating straightening, trimming, and additional precision techniques, enhancing its overall quality.
7. Coating treatment: To suit varied usage environments, the welded pipe's outer wall is expertly coated, significantly boosting its resistance to corrosion, abrasion, and environmental degradation.
Application fields of welded pipes
1. Construction field: As a cornerstone building material, welded pipes are indispensable in structures, steel frameworks, pipelines, power poles, and highway guardrails, offering strength and reliability.
2. Automotive manufacturing field: Welded pipes prove crucial in the automotive sector, utilized extensively in constructing frames, chassis, exhaust systems, and more, showcasing durability and versatility.
3. Industrial manufacturing field: Valued for their strength and resistance to corrosion, welded pipes are vital in machinery, shipbuilding, aerospace, and various industrial applications.
In short, welded pipes represent a critical metal material, celebrated for their diverse production processes and extensive application possibilities. The meticulous manufacturing process of welded pipes demands rigorous quality control, ensuring that each finished product meets the highest standards. In their application domain, the reach of welded pipes continues to broaden, promising a vibrant and expansive market potential.
