Production Process of Welded Pipes
1. Material Preparation: Our welded pipes are crafted from premium materials such as wide steel strips, hot-rolled steel strips, and cold-rolled steel strips, ensuring superior quality and durability. These materials undergo precise cutting, leveling, and cleaning to adhere to stringent process requirements, guaranteeing the excellence of the finished welded pipes.
2. Curling Forming: The meticulously processed steel strip is expertly formed into tubes of optimal diameter using advanced curling machines.
3. Welding Process: Utilizing cutting-edge high frequency induction welding or resistance welding, the curled tubes are seamlessly transformed into long, robust welded pipes.
4. Steel Annealing: Our precise annealing treatment reduces the hardness of the steel pipes, alleviating stress and enhancing the structural integrity of the finished product.
5. Size Cutting: The extended welded pipes are meticulously cut to precise lengths, tailored to meet specific process requirements.
6. Fine Repair Process: Each cut welded pipe undergoes meticulous fine-tuning, involving straightening, trimming, and precise processing to ensure flawless quality.
7. Coating Treatment: Tailored to the intended environment, the outer surface of the welded pipe is expertly coated to boost its resistance to corrosion, wear, and environmental factors.
Application Fields of Welded Pipes
1. Construction Field: Our welded pipes play a pivotal role in the construction industry, finding widespread use in building structures, steel frameworks, pipelines, power poles, and highway guardrails.
2. Automotive Manufacturing Field: In the automotive industry, welded pipes are essential for the production of frames, chassis, exhaust systems, and more, offering both resilience and reliability.
3. Industrial Manufacturing Field: Widely employed in industrial sectors including machinery, shipbuilding, and aerospace, our welded pipes deliver robust strength and exceptional corrosion resistance.
In summary, welded pipes stand as a critical metal material, characterized by diverse production processes and an expansive array of application fields.
