Detailed Photos

Daxun Alloys is proud to be a leading supplier of stainless steel tubing, adept at meeting diverse pipe demands. Type 304 stainless steel is an austenitic nickel alloy with an exceptionally low carbon content, making it perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy boasts remarkable strength, oxidation resistance, superb formability, and moderate machinability. For applications requiring enhanced resistance to intergranular corrosion, Daxun recommends 304L stainless steel, which offers superior immunity in highly corrosive environments. Our 304 stainless steel pipes are available in both seamless and welded forms and come in a variety of diameters. We also provide precision pipe cutting services to ensure your pipes are the exact length needed. Specializing in stainless steel pipes, Daxun invites you to contact us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strips, are expertly roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process ensures high integrity without the use of any filler metal.

Daxun is committed to delivering 304 stainless steel pipe products with exceptional speed and punctuality. This efficiency is backed by a robust system that integrates production capacity, information flow, logistics, and capital flow. For instance, Daxun's real-time order data seamlessly syncs with our logistics system. Our strategically located processing centers near ports, rivers, and seas ensure swift scheduling, rapid response, efficient storage, and transportation linkage. This meticulous orchestration guarantees the timely completion of tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are rolled and subsequently re-drawn to their final size. This rolling and drawing process is perfect for producing thick-walled, large-diameter tubes that can't be rolled directly to size, offering considerable cost savings over seamless tubes. Every drawn tube undergoes bright annealing for superior quality.

Daxun Advantages

• Wide Variety: We offer stainless steel pipes in a vast range of sizes and grades, from small to large diameters, including 304L, 316L, and more.
• Unmatched Flexibility: Whether your project demands seamless or welded steel pipes, our offerings can be tailored to meet your specific requirements.
• Quality Assurance: Our stainless steel pipes adhere to rigorous standards, including ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, guaranteeing top-notch reliability and performance.
• Custom Orders: In need of special sizes? We offer a variety of customization options for stainless steel pipes at competitive prices, plus the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are crafted by drawing from the hollow section of the tube, produced through piercing or hot extrusion processes. These tubes are ideal for applications requiring very large diameter-to-wall thickness ratios and boast excellent external dimensional tolerances.

Quality, Delivery, Inspection

• At Daxun, we conduct a comprehensive range of quality assurance tests including flattening tests, pitting and resistance tests, mechanical tests, hardness tests, material positive identification, and expansion tests. These evaluations ensure the material's suitability for its intended application.
• During production, we rigorously measure the diameter, thickness, and surface of each product. Our standard delivery timeframe is 7-15 days, except for special size products, which may extend to 20 days.
  Our delivery times are strictly adhered to as per the contract.
• We support third-party inspection agencies visiting our factory for assessments.
• We offer free samples to customers for testing purposes.
• Factory inspections can be conducted on-site or via video.
