Detailed Photos

Daxun Alloys proudly stands as a leading provider of stainless steel tubing, addressing an extensive range of pipe requirements. Our Type 304 stainless steel is an austenitic nickel alloy with a remarkably low carbon content, making it perfect for welding applications. Known as "18/8" stainless steel due to its 18% chromium and 8% nickel composition, it boasts exceptional strength, oxidation resistance, superior formability, and moderate machinability. For enhanced resilience against intergranular corrosion in harsh environments, we recommend our 304L stainless steel. Available in both seamless and welded forms, our 304 grade pipes come in various diameters. Additionally, we offer precise pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is ready to serve you.

Stainless Steel Welded Tubes

Crafted from stainless steel strip, our stainless steel tubular products are roll-formed and fusion-welded along the longitudinal seam. Daxun's innovative welding process omits the use of any filler metal, ensuring superior weld integrity.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products. Our speed is supported by a robust system encompassing production capacity, seamless information flow, and optimized logistics. Real-time data integration ensures swift order processing, while our strategically located processing centers-near ports, rivers, and seas-facilitate rapid response, efficient storage, and timely delivery, enhancing our commitment to punctuality.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are meticulously rolled and then re-drawn to their final dimensions. This rolling and drawing process is perfect for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering significant cost savings over seamless tubes. All our stainless steel drawn tubes undergo bright annealing for enhanced quality.

Daxun Advantages

• Varieties: Daxun offers an extensive range of stainless steel pipes, from small to large diameters, including grades such as 304L, 316L, and more.
• Flexibility: Whether your project requires seamless or welded steel pipes, our diverse stainless steel pipe options can meet your exact needs.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards like ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, guaranteeing reliability and top-tier performance.
• Custom Orders: Need specific sizes for your stainless steel pipes? We provide a range of customization options at competitive prices, along with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Produced by drawing from the hollow section of the tube, our stainless steel seamless tubes are created through piercing or hot extrusion processes. These tubes are ideal for large diameter-to-wall thickness ratios and offer excellent external dimensional tolerances.

Quality, delivery, inspection

• At Daxun, we perform a series of stringent quality assurance tests to ensure material suitability for all applications. These tests include flattening tests, pitting and resistance tests, mechanical tests, hardness tests, material positive identification, expansion tests, and more.
• Throughout production, we meticulously measure the diameter, thickness, and surface quality of our products. Our standard delivery time ranges from 7-15 days. For special size products, delivery may extend to 20 days.
  We strictly adhere to contract delivery times.
• We welcome third-party inspections at our factory.
• We provide free samples for customer testing.
• We support on-site and video factory inspections.
