Detailed Photos

Daxun Alloys proudly stands out as a premier supplier of stainless steel tubing, adept at fulfilling diverse pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, is perfect for welding applications. This alloy, known as "18/8" stainless steel due to its 18% chromium and 8% nickel composition, showcases remarkable strength, oxidation resistance, superior formability, and moderate machinability. For enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, which excels in highly corrosive environments. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms, available in various diameters. Additionally, we provide precision pipe cutting services to deliver products tailored to your exact length needs. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strips, our stainless steel tubular products undergo roll-forming and longitudinal seam fusion-welding. Notably, Daxun's welding process is distinguished by the absence of any filler metals, ensuring integrity and purity in the final product.

Daxun guarantees swift and efficient delivery of 304 stainless steel pipe products. This efficiency is driven by robust systems encompassing production capacity, information flow, logistics, and capital flow. For instance, our order data is seamlessly integrated with the logistics system in real time. Strategically located processing centers near ports and major waterways enable prompt scheduling, rapid response, and efficient storage, transportation, and loading, ensuring timely task completion.

 

Stainless Steel Drawn Tube

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

Daxun Advantages

• Varieties: We offer a vast array of stainless steel pipes, spanning from small to large diameters and available in multiple grades, including 304L and 316L.
• Flexibility: Whether your project demands seamless or welded steel pipes, our comprehensive range of stainless steel pipes can meet your specific needs.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unparalleled reliability and performance.
• Custom Orders: Seeking unique sizes of stainless steel pipes? We offer an extensive range of customization options at competitive prices, along with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are meticulously drawn from the hollow section of the tube, utilizing piercing or hot extrusion processes. These seamless tubes are ideal for applications requiring large diameter-to-wall thickness ratios and ensure superior external dimensional tolerances.

Quality, delivery, inspection

• At Daxun, we perform a battery of quality assurance tests, including flattening, pitting, resistance, mechanical, hardness, material identification, and expansion tests. These stringent tests ensure our material meets the highest standards for your specific 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 up to 20 days for certain special size products.
  Our delivery timelines strictly adhere to contractual agreements.
• We facilitate third-party agency inspections at our factory upon customer request.
• We offer free sample testing to our customers.
• We support both on-site and video factory inspections.
