Detailed Photos

Daxun Alloys takes pride in being a top supplier of stainless steel tubing capable of meeting a wide range of pipe demands. Type 304 stainless steel is an austenitic nickel alloy with extremely low carbon content, making it ideal for welding applications. It is essentially an austenitic chromium alloy, sometimes known as "18/8" stainless steel because it contains 18% chromium and 8% nickel. Our 304 stainless steel pipe boasts exceptional strength, outstanding oxidation resistance, superb formability, and moderate machinability. For environments requiring enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, which offers superior immunity in extremely corrosive conditions. Daxun Alloys provides 304 stainless steel pipe in seamless or welded forms and a wide range of diameters. We also offer precise pipe cutting services to match your exact length specifications. Specializing in stainless steel pipes, contact Daxun Alloys today.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process excludes any filler metal, ensuring the highest quality bonds.

Daxun guarantees timely and swift delivery of 304 stainless steel pipe products. Our rapid service is supported by an integrated system encompassing production capacity, information flow, logistics, and capital flow. Order data is instantly transmitted to our logistics system, ensuring seamless integration. Strategically located processing centers near ports, rivers, and seas facilitate efficient scheduling, rapid response times, and effective storage and transportation coordination, assuring that all tasks are completed punctually.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling followed by re-drawing to achieve their final size. This process is ideal for manufacturing thick-walled, large-diameter tubes that can't be directly rolled to size, offering cost advantages over seamless tubes. All our stainless steel drawn tubes are bright annealed for superior quality.

Daxun Advantages

• Varieties: Ranging from small to large diameter stainless steel pipes, we offer an extensive array of sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether you need seamless or welded steel pipes, our stainless steel pipes can be 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 reliability and superior performance.
• Custom Orders: In need of special sizes for your stainless steel pipes? We offer a variety of customization options at competitive prices with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are crafted from the hollow section of the tube, produced through piercing or hot extrusion processes. They are ideal for applications demanding high diameter-to-wall thickness ratios and exhibit excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun conducts comprehensive quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These rigorous tests guarantee that our materials meet the precise requirements for your applications.
• During production, we meticulously measure the diameter, thickness, and surface of each product. Our standard delivery time is 7-15 days; however, for special size products, delivery may extend to 20 days.
  We strictly adhere to the delivery times specified in our contracts.
• We welcome third-party agencies to conduct factory inspections.
• We offer free samples to customers for testing purposes.
• We support on-site or video factory inspections.
