Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling an extensive array of pipe requirements. Type 304 stainless steel, an austenitic nickel alloy with exceptionally low carbon content, is our specialty, perfect for welding applications. This alloy, known as '18/8' stainless steel, contains 18% chromium and 8% nickel, offering remarkable strength and oxidation resistance. Our 304 stainless steel pipe boasts excellent formability and moderate machinability. For enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, which performs splendidly in highly corrosive environments. At Daxun Alloys, our 304 stainless steel pipes are available in both seamless and welded forms, catering to a wide range of diameters. Additionally, we provide precise pipe cutting services to meet your specific length requirements. Daxun specializes in stainless steel pipes; reach out to us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strips, our tubular products undergo roll-forming and fusion-welding along the longitudinal seam. The welding process at Daxun is unique, as it employs no filler metal, resulting in a superior welded product.

Daxun ensures the timely and swift delivery of 304 stainless steel pipe products. This efficiency stems from a robust support system encompassing production capacity, information flow, logistics, and capital flow. Our order data is instantly integrated into our logistics system, guaranteeing seamless connectivity. Strategically located processing centers near ports and waterways enable rapid response, reasonable scheduling, efficient storage and transportation, and swift loading, ensuring timely completion of tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are meticulously rolled and subsequently re-drawn to achieve the final size. This process is ideal for producing thick-walled, large diameter tubes that cannot be directly rolled to size but still offer cost advantages over seamless tubes. All stainless steel drawn tubes are bright annealed, ensuring a flawless finish.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, we provide an extensive range of sizes and grades, including 304L, 316L, and more.
• Flexibility: Our seamless and welded stainless steel pipes are designed to meet the precise requirements of your unique projects.
• Quality Standards: Adhering to stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, our stainless steel pipes guarantee reliability and exceptional performance.
• Custom Orders: Seeking special sizes of stainless steel pipes? We offer an array of customization options at competitive prices, with convenient online ordering.

 

Stainless Steel Seamless Tube

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

Quality, Delivery, Inspection

• Daxun conducts comprehensive quality assurance tests including flattening tests, pitting and resistance tests, mechanical tests, hardness tests, material positive identification, expansion tests, and more. These rigorous tests ensure our materials are perfectly suited for their intended applications.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface quality of our products. Our standard delivery timeframe is 7-15 days, with a potential extension to 20 days for special size products.
  Our delivery schedule is meticulously aligned with contractual agreements.
• We support inspections by customer-designated third-party agencies at our factory.
• We offer free samples to customers for testing purposes.
• We facilitate on-site or video factory inspections to uphold transparency.
