Stainless Steel Welded Tubes
Our stainless steel tubular products, crafted from stainless steel strips, are roll-formed and longitudinally fusion-welded. Daxun's welding technique does not utilize any filler metal, ensuring the highest purity and integrity.
Daxun ensures swift and timely delivery of 304 stainless steel pipe products. Our efficiency is driven by a robust system encompassing production capacity, seamless information flow, logistics, and financial operations. Real-time data integration with our logistics system, strategic proximity of processing centers to ports, and efficient scheduling and storage mechanisms guarantee on-time completion of tasks.
Stainless Steel Drawn TubeOur stainless steel tubular products undergo rolling and re-drawing to achieve the final size. This process is optimal for manufacturing thick-walled, large-diameter tubes that cannot be directly rolled to size, offering cost efficiency compared to seamless tubes. Each stainless steel drawn tube is bright annealed for superior quality.
