Detailed Photos

Daxun Alloys takes immense pride in being a premier supplier of stainless steel tubing, adept at fulfilling a diverse spectrum of pipe requirements. Type 304 stainless steel is an austenitic nickel alloy with remarkably low carbon content, making it exceptionally suitable for welding applications. Essentially an austenitic chromium alloy, it is often referred to as '18/8' stainless steel due to its composition of 18% chromium and 8% nickel. Our 304 stainless steel pipe boasts unparalleled strength and oxidation resistance, excellent formability, and moderate machinability. For applications demanding heightened resistance to intergranular corrosion, we recommend 304L stainless steel, known for its superior immunity in extremely corrosive environments. Daxun Alloys offers 304 stainless steel pipe in both seamless and welded forms, available in a variety of diameters. We also provide precise pipe cutting services to ensure your products meet your exact length requirements. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us immediately for your needs.

Stainless Steel Welded Tubes

Stainless steel tubular products crafted from stainless steel strips are roll-formed and fusion-welded along the longitudinal seam. The unique welding process employed by Daxun does not utilize any filler metal, ensuring seamless integrity.

Daxun guarantees timely and swift delivery of 304 stainless steel pipe products. This efficiency stems from a robust system encompassing production capacity, information flow, to logistics, and capital flow. For instance, in terms of information flow, Daxun's order data seamlessly integrates with the logistics system in real-time. Logistically, our processing center's strategic proximity to ports, rivers, and seas enables efficient scheduling, rapid response, and coordinated storage and transportation, ensuring tasks are completed punctually.

 

Stainless Steel Drawn Tube

Stainless steel tubular products are initially rolled and then re-drawn to achieve the final size. This rolling and drawing process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size but still offer cost efficiencies over stainless steel seamless tubes. All stainless steel drawn tubes undergo a bright annealing process for a superior finish.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, we provide an extensive array of sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether your project requires seamless or welded steel pipes, our stainless steel pipes are designed to meet your specific needs.
• Quality Standards: Our stainless steel pipes adhere to stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring reliability and performance.
• Custom Orders: Seeking special sizes of stainless steel pipes? We offer diverse customization options at competitive prices, with convenient online ordering available.

 

Stainless Steel Seamless Tube

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

Quality, delivery, inspection

• Daxun conducts comprehensive quality assurance tests, including flattening tests, pitting and resistance tests, mechanical tests, hardness tests, material positive identification, and expansion tests. These rigorous tests ensure the material's suitability for its intended application.
• During the production process, we meticulously measure the diameter, thickness, and surface of the product. Our standard delivery time ranges from 7-15 days. For special size products, delivery may extend up to 20 days.
  Our delivery timelines are stringently adhered to as per the contractual agreement.
• We support customer third-party agencies to conduct factory inspections.
• We provide free samples to customers for testing purposes.
• We support on-site or video factory inspections.
