Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling diverse pipe requirements. The 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, excels in welding applications. Known as '18/8' stainless steel due to its composition of 18% chromium and 8% nickel, this alloy offers remarkable strength, oxidation resistance, excellent formability, and moderate machinability. For heightened resistance to intergranular corrosion in aggressive environments, we recommend 304L stainless steel. At Daxun Alloys, our 304 stainless steel pipes are available in both seamless and welded forms, spanning a variety of diameters. Additionally, we offer precision pipe cutting services to ensure your pipes meet exact length specifications. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us for unparalleled service.

Stainless Steel Welded Tubes

Crafted from stainless steel strip, our tubular products are roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process eliminates the need for any filler metal, ensuring superior quality.

Daxun guarantees timely and expedited delivery of 304 stainless steel pipe products. Our speed is supported by an integrated system from production capacity and information flow to logistics and financial management. For instance, our order data is synchronized in real-time with the logistics system, ensuring seamless data connectivity. Our strategically located processing centers near ports and rivers enable swift logistics, efficient storage and transportation, and prompt loading, thus ensuring on-time task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are rolled and subsequently re-drawn to achieve the final size. This technique is perfect for creating thick-walled, large-diameter tubes that cannot be directly rolled to size, offering cost benefits compared to seamless tubes. All our stainless steel drawn tubes undergo bright annealing for superior quality.

Daxun Advantages

• Varieties: We provide an extensive range of sizes and grades for stainless steel pipes, from small to large diameters, including 304L, 316L, and more.
• Flexibility: Our selection of seamless and welded steel pipes ensures that our stainless steel pipes can meet the specific demands of your project.
• Quality Standards: Our stainless steel pipes conform to rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring high reliability and performance.
• Custom Orders: Need special sizes for your stainless steel pipes? We offer a wide range of customization options at competitive prices with convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are created by drawing from the tube's hollow section, formed through piercing or hot extrusion processes. Ideal for high diameter-to-wall thickness ratios, these tubes boast 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 stringent tests ensure the material's suitability for its intended application.
• During production, we meticulously measure the product's diameter, thickness, and surface. Our standard delivery time is 7-15 days, with an extension to 20 days for special size products.
  Our delivery schedule is strictly in accordance with the contract.
• We support customer third-party agencies for factory inspections.
• We offer free samples to customers for testing.
• We provide support for on-site or video factory inspections.
