Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling a diverse array of pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-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 exceptional strength, oxidation resistance, excellent formability, and moderate machinability. For enhanced resistance to intergranular corrosion, we recommend our 304L stainless steel, ideal for highly corrosive environments. At Daxun Alloys, we provide 304 stainless steel pipes in both seamless and welded forms, available in various diameters. Additionally, our pipe cutting services ensure your products are tailored to your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to expert. Contact us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strips, our tubular products are roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process eliminates the need for any filler metal, ensuring impeccable quality.

Daxun ensures prompt and reliable delivery of 304 stainless steel pipe products. Our efficient system, which seamlessly integrates production capacity, information flow, logistics, and capital flow, supports this speed. For instance, our order data feeds directly into our logistics system in real-time, ensuring seamless operation. Strategically located processing centers near ports, rivers, and seas facilitate rapid response, efficient scheduling, and effective storage and transportation. This streamlined process guarantees timely completion of tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are rolled and subsequently re-drawn to their final size. This combined rolling and drawing process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size. This method offers cost advantages over seamless tubes while ensuring all drawn tubes are bright annealed for superior finish.

Daxun Advantages

• Varieties: We offer an extensive range of stainless steel pipes, from small to large diameters, in various grades including 304L, 316L, and more.
• Flexibility: Whether you require seamless or welded steel pipes, our versatile stainless steel pipes can be customized to meet your specific project needs.
• Quality Standards: Our stainless steel pipes comply with rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring exceptional reliability and performance.
• Custom Orders: Need special sizes of stainless steel pipes? We provide a variety of customization options at competitive prices, with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are drawn from the hollow section of the tube, created via piercing or hot extrusion processes. These tubes are perfect for applications requiring very large diameter-to-wall thickness ratios and exhibit excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun conducts multiple quality assurance tests including flattening, pitting resistance, mechanical, hardness, material positive identification, and expansion tests. These rigorous assessments ensure our materials meet the highest standards for your applications.
• During production, we meticulously measure the diameter, thickness, and surface of each product. Our standard delivery timeline is 7-15 days, with some special size products extending to 20 days.
  We strictly adhere to the delivery schedules outlined in our contracts.
• We welcome third-party inspections at our factories.
• We provide free samples for customer testing.
• We support both on-site and video factory inspections.
