Detailed Photos

Daxun Alloys is revered as a premier supplier of stainless steel tubing, meticulously designed to cater to an extensive array of pipe requirements. Renowned for its exceptional features, Type 304 stainless steel is an austenitic nickel alloy with ultra-low carbon content, making it the perfect choice for welding applications. This alloy is fundamentally an austenitic chromium composition, often referred to as '18/8' stainless steel due to its 18% chromium and 8% nickel composition. Our 304 stainless steel pipes boast superior strength, remarkable oxidation resistance, excellent formability, and moderate machinability. For applications demanding higher resistance to intergranular corrosion, we recommend 304L stainless steel, known for its superior resilience in harsh corrosive environments. At Daxun Alloys, we offer 304 stainless steel pipes in both seamless and welded forms, available in a wide range of diameters. Additionally, we provide precise pipe cutting services to deliver products tailored to your exact specifications. Daxun specializes in stainless steel pipes; contact us today to discuss your needs.

Premium Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from top-quality stainless steel strips, are roll-formed and fusion-welded along the longitudinal seam. The state-of-the-art welding process employed by Daxun is filler metal-free, ensuring unmatched product integrity.

Experience the swift and reliable delivery of 304 stainless steel pipe products with Daxun. Our rapid service is supported by robust systems spanning production capacity, information flow, logistics, and capital flow. For instance, in information flow, our order data integrates seamlessly with the logistics system in real-time, ensuring flawless coordination. Our logistical prowess, with processing centers strategically located near ports, rivers, and seas, coupled with efficient scheduling and rapid response, guarantees timely completion of tasks through streamlined storage, transportation, and efficient loading.

 

High-Quality Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and then re-drawing to achieve the final dimensions. This method is ideal for crafting thick-walled, large-diameter tubes that cannot be directly rolled to size, offering significant cost advantages over seamless tubes. All our stainless steel drawn tubes are bright annealed for superior quality.

Daxun's Unmatched Advantages

• Variety: We offer an extensive range of sizes and grades, from small to large diameter stainless steel pipes, including 304L, 316L, and more.
• Flexibility: Whether you require seamless or welded steel pipes, our stainless steel pipes are designed to meet your specific project requirements with ease.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards such as 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 diverse range of customization options at competitive prices, with convenient online ordering.

 

Superior Stainless Steel Seamless Tube

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

Commitment to Quality, Timely Delivery, and Rigorous Inspection

• At Daxun, we conduct comprehensive quality assurance tests, including flattening tests, pitting and resistance tests, mechanical tests, hardness tests, material positive identification, and expansion tests. These stringent tests ensure the material's suitability for its intended applications.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface of our products. Our standard delivery time ranges from 7 to 15 days, with an extended timeframe of up to 20 days for special-sized products.
  We strictly adhere to delivery timelines as outlined in the contract.
• We welcome third-party agencies for factory inspections.
• We offer free samples for customer testing.
• We support on-site or video factory inspections.
