Detailed Photos

Daxun Alloys, a premier name in stainless steel tubing, stands out by fulfilling diverse pipe requirements with unmatched precision. Our 304 stainless steel is an austenitic nickel alloy renowned for its exceptional weldability, thanks to its incredibly low carbon content. This alloy, often referred to as '18/8' stainless steel, contains 18% chromium and 8% nickel, ensuring high strength, superior oxidation resistance, excellent formability, and moderate machinability. For environments demanding superior intergranular corrosion resistance, we recommend our 304L variant, tailored for ultra-corrosive conditions. Offering both seamless and welded forms, our 304 stainless steel pipes come in a broad range of diameters. To cater to specific needs, we provide custom pipe cutting services. At Daxun Alloys, stainless steel pipes are our forte. Reach out to us today for your piping solutions.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from high-quality stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. Daxun's welding process is distinctive as it eliminates the need for filler metals, ensuring optimal purity and strength.

Daxun ensures rapid and efficient delivery of 304 stainless steel pipe products. Behind this speed lies a robust system encompassing production capacity, streamlined information flow, and integrated logistics and financial operations. For instance, our order data is instantly synced with the logistics system in real-time, ensuring seamless data integration. Strategically located processing centers near ports, rivers, and seas facilitate efficient scheduling, quick responses, and synchronized storage and transportation, guaranteeing timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are initially rolled and then re-drawn to achieve the final size. This rolling and drawing technique is ideal for producing thick-walled, large-diameter tubes that cannot be directly rolled to size, offering significant cost savings over seamless tubes. Each stainless steel drawn tube undergoes bright annealing for superior finish.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, our product range encompasses a vast array of sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether your project demands seamless or welded steel pipes, our offerings can be customized to meet your specific requirements.
• Quality Standards: Adhering to stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, our stainless steel pipes guarantee exceptional reliability and performance.
• Custom Orders: Need special sizes of stainless steel pipes? Explore our myriad customization options available at competitive prices, along with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our seamless stainless steel tubes are drawn from the hollow section of the tube, created through piercing or hot extrusion processes. Ideal for applications requiring large diameter-to-wall thickness ratios, these tubes boast excellent external dimensional tolerances.

Quality, delivery, inspection

• At Daxun, we perform rigorous quality assurance tests such as flattening tests, pitting and resistance tests, mechanical tests, hardness tests, material positive identification, and expansion tests. These rigorous evaluations ensure that our materials meet the highest standards for their intended applications.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface quality of our products. Our standard delivery time ranges from 7 to 15 days, extending to 20 days for special size orders.
  We strictly adhere to contractually agreed delivery times.
• We welcome customer third-party agencies to inspect our factory.
• We offer free samples to customers for testing purposes.
• We support both on-site and video factory inspections.
