Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling diverse pipe requirements. Crafted from Type 304 stainless steel-an austenitic nickel alloy with minimal carbon content-our tubing is perfect for welding applications. This alloy, often known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, offers outstanding strength, oxidation resistance, formability, and moderate machinability. For environments demanding superior resistance to intergranular corrosion, we recommend 304L stainless steel. Available in both seamless and welded forms, our 304 stainless steel pipes come in various diameters, and we provide precise pipe cutting services to meet exact specifications. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us today.

Stainless Steel Welded Tubes

Daxun's stainless steel tubular products are crafted from stainless steel strips that are roll-formed and fusion-welded along the longitudinal seam without the use of filler metal, ensuring robust and clean welds.

Daxun guarantees timely and swift delivery of 304 stainless steel pipe products, backed by our advanced system capabilities in production, information flow, logistics, and capital flow. Real-time order data integration with our logistics system, strategic proximity to ports and rivers, efficient scheduling, and rapid storage and transportation linkage ensure on-time task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products, after being rolled, are re-drawn to achieve the final size. This method is particularly beneficial for producing thick-walled, large-diameter tubes that cannot be directly rolled, offering a cost-effective alternative to seamless tubes. All drawn tubes undergo bright annealing for enhanced finish.

Daxun Advantages

• Varieties: We offer an extensive range of stainless steel pipes, from small to large diameters, including grades like 304L, 316L, and more.
• Flexibility: Whether you require seamless or welded pipes, our stainless steel pipes are tailored to meet your specific project needs.
• Quality Standards: Our stainless steel pipes comply with rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring optimal reliability and performance.
• Custom Orders: Need unique sizes of stainless steel pipes? We offer a range of customization options at competitive prices, with convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are drawn from hollow sections created by piercing or hot extrusion processes, ideal for large diameter-to-wall thickness ratios, offering precise external dimensional tolerances.

Quality, delivery, inspection

• Daxun performs a series of quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material identification, and expansion tests, ensuring our materials meet all required applications.
• Throughout production, we monitor the diameter, thickness, and surface quality of our products. Our standard delivery timeframe is 7-15 days, extending to 20 days for some special sizes.
  We adhere strictly to contractual delivery times.
• We welcome third-party agency inspections at our factory.
• We offer free sample testing to customers.
• We support on-site or video factory inspections.
