Detailed Photos

Daxun Alloys is renowned for being a premier supplier of stainless steel tubing, adept at meeting diverse pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy with exceptionally low carbon content, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy offers outstanding strength and oxidation resistance, excellent formability, and moderate machinability. For settings requiring heightened resistance to intergranular corrosion, we recommend 304L stainless steel, renowned for its superior immunity in highly corrosive environments. Daxun Alloys provides 304 stainless steel pipe in both seamless and welded forms, available in a broad spectrum of diameters. To tailor your order precisely to your needs, we also offer bespoke pipe cutting services. Specialising in stainless steel pipes, Daxun Alloys is your go-to partner-reach out to us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strips, our stainless steel tubular products undergo roll-forming and fusion welding along the longitudinal seam. Daxun's advanced welding technique eschews the use of any filler metal, ensuring superior quality and structural integrity.

Daxun guarantees the prompt and efficient delivery of our 304 stainless steel pipe products, backed by an integrated system encompassing production capacity, information flow, logistics, and capital flow. For instance, our order data is instantly relayed to the logistics system, ensuring seamless data integration. Situated near ports, rivers, and seas, our processing center enables efficient scheduling, rapid response, coordinated storage and transportation, and quick loading, all of which assure timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are first rolled and then re-drawn to their final size. This method is optimum for producing tubes with thick walls and large diameters that cannot be directly rolled to size, offering cost advantages over stainless steel seamless tubes. All our stainless steel drawn tubes undergo a bright annealing process.

Daxun Advantages

• Varieties: We provide a broad range of sizes and grades, from small to large diameter stainless steel pipes, including 304L, 316L, and more.
• Flexibility: Whether you require seamless or welded steel pipes, our stainless steel pipes are designed to meet your specific project needs.
• 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: Seeking special sizes of stainless steel pipes? We offer extensive customization options at competitive prices, along with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel tubular products are derived from the hollow section of the tube, produced through piercing or hot extrusion processes. The stainless steel seamless tube is ideal for applications requiring large diameter-to-wall thickness ratios and boasts excellent external dimensional tolerances.

Quality, delivery, inspection

• Daxun executes a comprehensive range of quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These rigorous evaluations ensure the material meets the precise requirements of its intended application.
• Throughout production, we meticulously measure the diameter, thickness, and surface of our products. Our standard delivery timeframe is 7-15 days, extending to 20 days for certain custom sizes.
  We strictly adhere to contractual delivery schedules.
• We welcome customer third-party agencies to conduct factory inspections.
• We offer free samples for customer testing.
• We support both on-site and video factory inspections.
