Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, designed to meet diverse pipe requirements. Our Type 304 stainless steel is an austenitic nickel alloy with 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, this alloy offers outstanding strength, oxidation resistance, excellent formability, and moderate machinability. For environments requiring superior resistance to intergranular corrosion, we recommend 304L stainless steel, which excels in extremely harsh conditions. At Daxun Alloys, we stock 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 exact lengths. Specializing in stainless steel pipes, Daxun Alloys is your go-to source. Contact us today!

Stainless Steel Welded Tubes

Our stainless steel tubular products are roll-formed and longitudinally fusion-welded from stainless steel strips. Notably, Daxun's welding process operates without the use of any filler metal, ensuring precision and integrity.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products, made possible through our robust systems encompassing production capacity, information flow, logistics, and capital flow. For instance, our order data is pushed to our logistics system in real-time, ensuring seamless integration. Strategically located processing centers near ports, rivers, and seas enable swift scheduling, rapid response, synchronized storage and transportation, efficient loading, and timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and subsequent re-drawing to achieve their final size. This process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering cost benefits over seamless tubes. All our stainless steel drawn tubes undergo bright annealing to ensure superior quality.

Daxun Advantages

• Varieties: Offering a wide assortment of sizes and grades, including 304L, 316L, and many more, we cater to both small and large diameter stainless steel pipe needs.
• Flexibility: Whether your project requires seamless or welded steel pipes, our diverse range of stainless steel pipes is designed to meet your specific requirements.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unmatched reliability and performance.
• Custom Orders: In need of special sizes? We offer diverse customization options for stainless steel pipes at competitive prices, with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our seamless stainless steel tubes, drawn from hollow sections created by piercing or hot extrusion processes, are perfect for applications requiring significant diameter-to-wall thickness ratios. These tubes possess excellent external dimensional tolerances.

Quality, delivery, inspection

• Daxun conducts extensive quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These ensure our materials are well-suited for their intended applications.
• Throughout production, we meticulously measure diameter, thickness, and surface quality. Our standard delivery time ranges from 7-15 days, extending up to 20 days for specially sized products.
  Our delivery schedules strictly adhere to contractual agreements.
• We support third-party agency inspections at our factory.
• Free samples are available for customers to test.
• We offer on-site or video factory inspections.
