Detailed Photos

Daxun Alloys takes immense pride in being a premier supplier of stainless steel tubing, engineered to cater to a myriad of pipe demands. Our Type 304 stainless steel is an austenitic nickel alloy with ultra-low carbon content, making it the ideal choice for welding applications. This alloy, commonly known as "18/8" stainless steel, contains 18% chromium and 8% nickel, conferring it with exceptional strength, oxidation resistance, superb formability, and moderate machinability. For applications demanding enhanced resistance to intergranular corrosion, we recommend our 304L stainless steel, which offers superior immunity in highly corrosive environments. At Daxun Alloys, we provide 304 stainless steel pipes in both seamless and welded forms, available in a wide range of diameters. Our precise pipe cutting services ensure that your pipe products meet your exact length requirements. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us today to fulfill all your pipe needs.

Stainless Steel Welded Tubes

Our stainless steel tubular products, made from high-quality stainless steel strips, are expertly roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process ensures no filler metal is used, guaranteeing optimal purity and strength of the weld.

Daxun ensures timely and rapid delivery of 304 stainless steel pipe products. Our unparalleled speed is backed by a robust system encompassing production capacity, real-time information flow, seamless logistics, and efficient capital management. For instance, our order data is instantly pushed to our logistics system, ensuring seamless data integration. Proximity to ports and rivers allows our processing center to execute reasonable scheduling, rapid response, coordinated storage, and transportation, ensuring task completion within deadlines.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are precisely rolled and subsequently re-drawn to achieve the final size. This rolling and drawing process is perfect for manufacturing thick-walled, large-diameter tubes that cannot be directly rolled to size, while still providing cost savings over seamless tubes. Every drawn tube undergoes bright annealing for a flawless finish.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, Daxun offers an extensive range of sizes and grades, including 304L, 316L, and more, to suit your diverse needs.
• Flexibility: Whether you require seamless or welded steel pipes, our stainless steel products are designed to meet the specific demands of your projects.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unmatched reliability and performance.
• Custom Orders: Seeking specialized sizes in stainless steel pipes? We offer a broad array of customization options at competitive prices with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel tubular products are meticulously drawn from the hollow section of the tube, produced through advanced piercing or hot extrusion processes. Stainless steel seamless tubes are ideal for applications requiring very large diameter to wall thickness ratios, offering excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun conducts comprehensive quality assurance tests, including flattening, pitting, resistance, mechanical, hardness, material positive identification, and expansion tests. These rigorous tests ensure the material is perfectly suited for its intended application.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface quality of our products. Our standard delivery time is 7-15 days; however, for some specialized sizes, the delivery time extends to 20 days.
  We strictly adhere to contractually agreed delivery times, ensuring reliability and trust.
• We support customer third-party agencies conducting factory inspections, guaranteeing transparency and quality.
• We offer free samples for customers to test and evaluate our products' quality.
• Our support extends to on-site or video factory inspections, providing peace of mind regarding our production processes.
