Detailed Photos

Daxun Alloys takes pride in being a premier supplier of stainless steel tubing, expertly meeting diverse pipe demands. Our 304 stainless steel is an austenitic nickel alloy with exceptionally low carbon, perfect for welding applications. Known as '18/8' stainless steel, it boasts 18% chromium and 8% nickel content, offering exceptional strength, oxidation resistance, superb formability, and moderate machinability. For enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, ideal for highly corrosive environments. Our 304 stainless steel pipes are available in both seamless and welded forms, with a variety of diameters to choose from. We also provide precise pipe cutting services, ensuring your products meet exact length requirements. 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 fusion-welded along the longitudinal seam. Daxun's advanced welding process is filler metal-free, ensuring seamless strength and durability.

Daxun ensures timely and rapid delivery of 304 stainless steel pipe products. This efficiency is backed by robust systems, from production capacity to logistics and capital flow. For instance, our real-time order data integration with the logistics system ensures seamless data flow. Proximity to ports, rivers, and seas, coupled with efficient scheduling, storage, transportation, and loading, allows us to meet deadlines flawlessly.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are rolled, then re-drawn to the final size. This process is ideal for manufacturing thick-walled, large-diameter tubes that can't be rolled directly to size, offering cost savings over seamless tubes. All drawn tubes undergo bright annealing for optimal quality.

Daxun Advantages

• Varieties: We offer a comprehensive range of sizes and grades, from small to large diameter stainless steel pipes, including 304L, 316L, and more.
• Flexibility: Our stainless steel pipes, available in seamless and welded forms, are tailored to meet your specific project requirements.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unmatched reliability and performance.
• Custom Orders: Need special sizes? We provide a variety of stainless steel pipe customization options at competitive prices and convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are drawn from the hollow section of the tube, created through piercing or hot extrusion processes. Ideal for large diameter to wall thickness ratios, these tubes offer excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun conducts extensive quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These evaluations guarantee material suitability for any application.
• Throughout production, we meticulously measure the diameter, thickness, and surface of each product. Our standard delivery time is 7-15 days, extending to 20 days for special size products.
  Our delivery time strictly adheres to contract terms.
• We support third-party agency inspections at our factory.
• We offer free samples for customer testing.
• We support on-site or video factory inspections.
