Daxun Alloys is proud to be a premier supplier of stainless steel tubing, expertly catering to diverse piping needs. Our Type 304 stainless steel, an austenitic nickel alloy with low carbon content, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, it offers exceptional strength, oxidation resistance, formability, and moderate machinability. For superior resistance to intergranular corrosion, our 304L stainless steel is an ideal choice, excelling in highly corrosive environments. We offer 304 stainless steel pipes in both seamless and welded forms, with a variety of diameters. Our pipe cutting services ensure your products meet precise length specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to provider. Contact us today!

Stainless Steel Welded Tubes

Our stainless steel tubular products are crafted from stainless steel strips that are roll-formed and fusion-welded along the longitudinal seam. Daxun employs a welding process that uses no filler metal, ensuring the highest integrity and quality.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products. This speed is backed by our robust production capacity, seamless information flow, and strategic logistics and capital flow management. Our synchronized order and logistics systems ensure real-time data transfer, while our proximity to ports and waterways facilitates rapid response and efficient loading. This ensures timely completion of all tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are initially rolled and subsequently re-drawn to achieve the final size. This method is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering cost savings over seamless tubes. All our stainless steel drawn tubes undergo bright annealing.

Daxun Advantages

• Varieties: From small to large diameters, we offer a comprehensive range of stainless steel pipes in various sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether you require seamless or welded steel pipes, our offerings can meet your specific project requirements with precision.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring top-tier reliability and performance.
• Custom Orders: Need custom-sized stainless steel pipes? We provide a wide range of customization options at competitive prices, with convenient online ordering for your ease.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are drawn from the hollow sections, created through piercing or hot extrusion processes. These tubes are perfect for large diameter-to-wall thickness ratios and boast excellent external dimensional tolerances.

Quality, delivery, inspection

• To ensure material suitability, Daxun conducts several rigorous quality assurance tests, including flattening, pitting resistance, mechanical, hardness, positive material identification, and expansion tests.
• Throughout production, we meticulously measure the diameter, thickness, and surface of our products. Standard delivery time is 7-15 days, extending to 20 days for special size products.
  Our delivery timelines strictly adhere to contractual agreements.
• We support inspections by customer-chosen third-party agencies at our factory.
• We offer free samples to customers for testing purposes.
• We support both on-site and video-based factory inspections.
