Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adeptly fulfilling a diverse array of pipe requirements. Type 304 stainless steel, an austenitic nickel alloy, boasts an extraordinarily low carbon content, making it perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy offers remarkable strength, oxidation resistance, superior formability, and moderate machinability. For heightened resistance to intergranular corrosion, we recommend 304L stainless steel, which thrives in highly corrosive environments. At Daxun Alloys, we provide 304 stainless steel pipes in both seamless and welded forms across a wide range of diameters. Additionally, our pipe cutting services ensure your products meet precise length specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to partner for all your piping needs. Contact us 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 ensures no filler metal is used, maintaining the purity and integrity of the stainless steel.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products. This speed is underpinned by a robust system of production capacity, streamlined information flow, and efficient logistics and capital management. For instance, our real-time order data integration with the logistics system ensures seamless data connectivity. Strategically located processing centers near ports, rivers, and seas facilitate optimal scheduling, rapid response, coordinated storage and transportation, and efficient loading, ensuring timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo an additional rolling and re-drawing process to achieve their final size. This method is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering significant cost savings over stainless steel seamless tubes. All stainless steel drawn tubes are bright annealed for a superior finish.

Daxun Advantages

• Varieties: Our extensive range of stainless steel pipes includes sizes and grades from small to large diameters, featuring 304L, 316L, and more.
• Flexibility: Whether your project demands seamless or welded steel pipes, our stainless steel pipes are tailored to meet your specific requirements.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards, including ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unparalleled reliability and performance.
• Custom Orders: Seeking special sizes of stainless steel pipes? We offer a variety of customization options at competitive prices, along with convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are meticulously drawn from the hollow section of the tube, produced through piercing or hot extrusion processes. Ideal for large diameter-to-wall thickness ratios, these tubes offer exceptional 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 evaluations ensure that our materials are perfectly suited for your applications.
• Throughout production, we consistently measure the diameter, thickness, and surface quality of our products. Our standard delivery time is 7-15 days. For special sizes, delivery extends to 20 days, ensuring timely completion.
  Our delivery schedule strictly adheres to the contractual agreement.
• We support customer-initiated third-party inspections at our factory.
• Daxun offers free samples to customers for testing purposes.
• We facilitate on-site or video factory inspections for our customers.
