Detailed Photos

Daxun Alloys takes immense pride in being a top-tier supplier of stainless steel tubing, adeptly meeting a diverse range of pipe requirements. Our Type 304 stainless steel is an austenitic nickel alloy with an extremely low carbon content, making it ideal for welding applications. Known as an austenitic chromium alloy, sometimes referred to as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, our 304 stainless steel pipe boasts exceptional strength, oxidation resistance, superior formability, and moderate machinability. For applications demanding heightened resistance to intergranular corrosion, we recommend 304L stainless steel, famed for its superior immunity in highly corrosive environments. Daxun Alloys offers 304 stainless steel pipe in both seamless and welded forms, across a wide range of diameters. We also provide precision pipe cutting services to ensure your pipe products meet your exact length specifications. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us today.

Stainless Steel Welded Tubes

Crafted from premium stainless steel strips, our stainless steel tubular products are roll-formed and fusion-welded along the longitudinal seam. Daxun's sophisticated welding process eschews the use of any filler metals, ensuring pure, robust welds.

Daxun ensures the timely and swift delivery of 304 stainless steel pipe products, backed by a robust system encompassing production capacity, information flow, logistics, and financial resources. For instance, our order data is instantly pushed to the logistics system, enabling seamless data integration. Strategically located near ports and waterways, our processing center benefits from efficient scheduling, rapid response, and streamlined storage and transportation, guaranteeing punctual task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and subsequent re-drawing to achieve their final size. This method is ideal for manufacturing thick-walled, large-diameter tubes that cannot be rolled directly to size, yet offer significant cost savings over stainless steel seamless tubes. All our drawn tubes are bright annealed for a flawless finish.

Daxun's Unparalleled Advantages

• Variety: From small to large diameter stainless steel pipes, we offer an extensive range 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 requirements.
• Quality Standards: Our stainless steel pipes adhere to stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring unmatched reliability and performance.
• Custom Orders: Seeking specialized sizes of stainless steel pipes? We offer a plethora of customization options at competitive prices with convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel tubular products are drawn from the hollow section of the tube, produced through piercing or hot extrusion processes. Ideal for large diameter-to-wall thickness ratios, stainless steel seamless tubes offer excellent external dimensional tolerances.

Quality, Delivery, and Inspection

• At Daxun, we conduct rigorous quality assurance tests, including flattening, pitting and resistance, mechanical, hardness, material positive identification, and expansion tests. These comprehensive tests ensure the material's suitability for your required applications.
• Throughout the production process, we meticulously measure the diameter, thickness, and surface finish of our products. Our standard delivery time is 7-15 days. For special size products, the delivery time may extend up to 20 days.
  We strictly adhere to contractually agreed delivery times.
• We support inspection by third-party agencies at our factory.
• We offer free samples for customer testing.
• We support on-site or video inspections of our factory.
