Production Process of Welded Pipes
1. Material Preparation: The creation of our welded pipes begins with exceptional materials including wide steel strips, hot-rolled steel strips, and cold-rolled steel strips. These superior materials are meticulously cut, leveled, and cleansed to align with stringent process requirements, ensuring the supreme quality of the finished welded pipes.
2. Curling Forming: Once processed, the steel strip is elegantly shaped into a small diameter tube by a sophisticated curling machine.
3. Welding Process: Utilizing advanced high-frequency induction welding or resistance welding processes, the curled tube is expertly transformed into a seamless long welded pipe.
4. Steel Annealing: Through precise annealing treatment, we reduce the hardness, stress level, and internal stress of the steel pipe, enhancing its overall durability.
5. Size Cutting: The long welded pipe is precisely cut to the desirable length according to detailed process requirements, ensuring fit-for-purpose solutions.
6. Fine Repair Process: The cut welded pipe undergoes a refined finishing process, including straightening, trimming, and additional meticulous preparations to ensure perfection.
7. Coating Treatment: Tailored to the intended usage environment, the pipe's outer wall receives a specialized coating to enhance its resistance against corrosion, wear, and additional environmental challenges.
Application Fields of Welded Pipes
1. Construction Field: Renowned in construction, our welded pipes are integral to building structures, steel frameworks, pipelines, power poles, and highway guardrails, proving their versatility.
2. Automotive Manufacturing Field: In automotive manufacturing, welded pipes are indispensable, skillfully incorporated into frames, chassis, and exhaust systems.
3. Industrial Manufacturing Field: With robust strength and corrosion resistance, welded pipes are extensively utilized in the manufacturing of machinery, ships, and airplanes.
In essence, welded pipes, as a cornerstone metal material, boast diverse production processes and versatile applications. The meticulous process of manufacturing welded pipes demands rigorous control to guarantee impeccable quality in the final product. Across various fields, the scope of welded pipe applications is ever-expanding, revealing expansive market prospects.
