Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling diverse pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy, boasts ultra-low carbon content, ideal for welding. This '18/8' stainless steel contains 18% chromium and 8% nickel, offering exceptional strength, oxidation resistance, superb formability, and moderate machinability. For heightened resistance to intergranular corrosion, Daxun recommends 304L stainless steel, perfect for severely corrosive environments. Our 304 stainless steel pipes are available in both seamless and welded forms, across various diameters, with custom pipe cutting services to meet your exact specifications. Daxun specializes in stainless steel pipes; reach out to us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strips, undergo roll-forming and fusion-welding along the longitudinal seam. Daxun's welding process is unique as it uses no filler metal, ensuring purity and strength.

Daxun ensures timely and rapid delivery of 304 stainless steel pipe products. Our efficiency stems from robust systems encompassing production capacity, information flow, and logistics. We push order data to the logistics system in real-time for seamless connectivity. Our processing center's proximity to ports, rivers, and seas enables efficient logistic planning, swift responses, and effective storage and transportation, guaranteeing on-time task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are rolled and subsequently re-drawn to their final sizes. This method is ideal for manufacturing thick-walled, large diameter tubes, which can't be rolled directly to size but offer significant cost savings over seamless tubes. All drawn tubes undergo bright annealing for superior quality.

Daxun Advantages

• Varieties: We offer an extensive range of sizes and grades, from small to large diameter stainless steel pipes, including 304L, 316L, and more.
• Flexibility: Our stainless steel pipes, available in seamless or welded forms, can cater to your specific project requirements.
• Quality Standards: Our pipes adhere to rigorous standards like ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring top-notch reliability and performance.
• Custom Orders: Need special sizes for your stainless steel pipes? We provide various customization options at competitive prices with easy online ordering.

 

Stainless Steel Seamless Tube

Our seamless stainless steel tubular products are drawn from hollow sections made via piercing or hot extrusion. These tubes are perfect for large diameter-to-wall thickness ratios and maintain excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun performs numerous quality assurance tests, including flattening, pitting, resistance, mechanical, hardness, material identification, and expansion tests. These ensure our materials are fit for their intended applications.
• Throughout production, we meticulously measure the diameter, thickness, and surface of our products. Standard delivery time is 7-15 days; for special sizes, up to 20 days.
  Our delivery schedules strictly adhere to contractual agreements.
• We support customer inspections by third-party agencies at our factory.
• Free sample provision is available for customer testing.
• We facilitate both on-site and video factory inspections.
