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 and oxidation resistance, great formability, and moderate machinability. For applications requiring increased resistance to intergranular corrosion, we propose 304L stainless steel, which has superior immunity in severely corrosive situations. Daxun Alloys offers 304 stainless steel pipe in seamless or welded forms. Available in a range of diameters, we also provide pipe cutting services to ensure your pipe products are the exact length you require. Specializing in stainless steel pipes, contact Daxun today.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strip, are roll-formed and fusion-welded along the longitudinal seam. The advanced welding process used by Daxun ensures no filler metal is needed, guaranteeing superior quality.

Daxun ensures timely and fast delivery of 304 stainless steel pipe products. This efficiency is backed by robust system support encompassing production capacity, information flow, logistics, and capital flow. For instance, our order data integrates seamlessly with the logistics system in real-time, ensuring swift transitions; our logistics center's proximity to ports and rivers facilitates efficient scheduling, rapid responses, storage and transportation coordination, and swift loading, ensuring tasks are completed on time.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and then re-drawing to achieve their final size. This method is ideal for thick-walled, large-diameter tubes that cannot be rolled directly to size but still offer cost savings over seamless tubes. All stainless steel drawn tubes are bright annealed, ensuring premium quality.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, we offer a comprehensive range of sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether you need seamless or welded steel pipes, our stainless steel pipes are tailored to meet your specific project requirements.
• Quality Standards: Our stainless steel pipes adhere to stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring outstanding reliability and performance.
• Custom Orders: Seeking special sizes of stainless steel pipes? We provide a variety of customization options at competitive prices and convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel tubular products are drawn from the hollow section of the tube, made by piercing or hot extrusion processes. Ideal for very large diameter-to-wall thickness ratios, stainless steel seamless tubes offer excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun conducts rigorous quality assurance tests, including flattening, pitting, resistance, mechanical, hardness, material positive identification, and expansion tests. These ensure the material's suitability for the required application.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface of the product. Our standard delivery time is 7-15 days. For special size products, delivery may extend to 20 days.
  Our delivery schedule strictly adheres to the contractual agreement.
• We support third-party agencies to inspect our factory.
• We offer free samples to customers for testing.
• We support on-site or video factory inspections.
