Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling varied pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, it excels in strength and oxidation resistance, formability, and moderate machinability. For superior resistance to intergranular corrosion, our 304L stainless steel is the ideal choice in highly corrosive environments. We offer 304 stainless steel pipes in both seamless and welded forms, available in a variety of diameters. Additionally, we provide precise pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to source. Contact us today.

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 Tube

Our 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.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, we provide an extensive range of sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether you need seamless or welded steel pipes, our stainless steel pipes can cater to your specific project needs.

• Custom Orders: Seeking unique sizes of stainless steel pipes? We offer a wide array of customization options, competitive pricing, and convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are drawn from hollow sections made via piercing or hot extrusion processes. Ideal for large diameter-to-wall thickness ratios, they boast exceptional external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun conducts rigorous quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These evaluations ensure the material's suitability for its intended application.
• Throughout production, we meticulously measure diameter, thickness, and surface quality. Our standard delivery timeframe is 7-15 days, extending to 20 days for special sizes.
  We strictly adhere to contractually agreed delivery times.
