Detailed Photos

Daxun Alloys takes pride in being a leading supplier of stainless steel tubing that meets diverse pipe demands. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, is perfect for welding applications. Often referred to as '18/8' stainless steel, it comprises 18% chromium and 8% nickel, offering exceptional strength, oxidation resistance, great formability, and moderate machinability. For enhanced intergranular corrosion resistance, we recommend 304L stainless steel, optimized for severely corrosive conditions. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms across various diameters. We also provide precision pipe-cutting services to ensure exact lengths. Specializing in stainless steel pipes, Daxun Alloys is your trusted partner-contact us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strip, our tubular products are roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process ensures no filler metal is used during welding, maintaining the integrity of the stainless steel.

Daxun guarantees timely and efficient delivery of 304 stainless steel pipe products. Underpinning this speed is our robust system, from production capacity and information flow to logistics and capital flow. For instance, our real-time order data seamlessly integrates with our logistics system. Strategically located near ports, rivers, and seas, our processing center ensures rapid response, reasonable scheduling, efficient storage, transportation linkage, and expedited loading, ensuring on-time task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are rolled and then re-drawn to achieve the final size. This rolling and drawing process is perfect for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering cost savings over seamless tubes. All our drawn tubes are bright annealed, ensuring a high-quality finish.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, Daxun offers an extensive array of sizes and grades, including 304L, 316L, and more.

• Quality Standards: Our stainless steel pipes adhere to stringent standards like ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unparalleled reliability and performance.
• Custom Orders: Need special sizes? We offer a wide range of stainless steel pipe customization options at competitive prices, with the ease of online ordering.

 

Stainless Steel Seamless Tube

Our seamless tubular products, drawn from the hollow section of the tube made by piercing or hot extrusion, are ideal for large diameter-to-wall thickness ratios, offering excellent external dimensional tolerances.

Quality, Delivery, Inspection

• Daxun performs several quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These tests ensure our materials meet your specific application needs.
• Throughout production, we meticulously measure the diameter, thickness, and surface of each product. Our standard delivery window is 7-15 days, extending to 20 days for special sizes.
  We strictly adhere to contractually agreed delivery times.
• We support customer third-party agencies for factory inspections.
• We offer free samples to customers for testing.
• We facilitate on-site or video factory inspections.
