Detailed Photos

Daxun Alloys proudly stands at the forefront as a premier supplier of stainless steel tubing, adept at satisfying a diverse range of piping needs. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, is particularly suited for welding applications. This alloy, known as '18/8' due to its 18% chromium and 8% nickel content, boasts exceptional strength and oxidation resistance, excellent formability, and moderate machinability. For applications demanding heightened resistance to intergranular corrosion, we recommend 304L stainless steel, offering superior immunity in highly corrosive environments. At Daxun Alloys, you'll find 304 stainless steel pipe available in both seamless and welded forms, spanning a broad range of diameters. Additionally, we provide precise pipe cutting services to meet your exact length specifications. Specializing in stainless steel pipes, we invite you to reach out to Daxun for all your piping needs.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strip, are roll-formed and fusion-welded along the longitudinal seam with precision. Daxun employs a welding technique that eschews the use of any filler metal, ensuring the highest quality welds.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products. This speed is backed by robust system support, encompassing production capacity, information flow, logistics, and capital flow. For example, our order data is instantly pushed to the logistics system, ensuring seamless data integration. Strategically located processing centers near ports and waterways allow for optimal scheduling, rapid response, synchronized storage and transport, and efficient loading. This comprehensive system ensures timely completion of all tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and then re-drawing to achieve final size. This process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size while still offering cost savings compared to seamless tubes. Every stainless steel drawn tube is bright annealed for superior quality.

Daxun Advantages

• Varieties: We offer an extensive array of sizes and grades, from small to large diameter stainless steel pipes, including 304L, 316L, and more.
• Flexibility: Whether your project calls for seamless or welded steel pipes, our versatile stainless steel pipes can fulfill your specific requirements.
• Quality Standards: Our stainless steel pipes adhere to stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring their reliability and high performance.
• Custom Orders: Need special sizes of stainless steel pipes? We provide a wide range of customization options at competitive prices with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel tubular products are meticulously drawn from the hollow section of the tube, created by piercing or hot extrusion processes. The seamless tubes are perfect for applications requiring large diameter-to-wall thickness ratios and feature 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 rigorous tests ensure that our materials meet all application requirements.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface of each product. Our standard delivery time ranges from 7 to 15 days, extending to 20 days for special size products.
