Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing designed to meet diverse piping needs. Our Type 304 stainless steel, an austenitic nickel alloy with low carbon content, is especially suitable for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy ensures remarkable strength and oxidation resistance, superior formability, and moderate machinability. For applications that demand heightened resistance to intergranular corrosion, our 304L variant offers enhanced immunity in highly corrosive environments. Available in both seamless and welded forms, our 304 grade pipes come in various diameters. We also offer tailored pipe cutting services to meet your specific length requirements. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products are meticulously crafted from stainless steel strips, roll-formed, and fusion-welded along the longitudinal seam. Daxun's welding process notably omits the use of filler metal, ensuring a purer weld.

Daxun guarantees prompt and reliable delivery of 304 stainless steel pipe products, supported by an efficient production, information flow, and logistics system. For instance, our order data is instantaneously integrated into the logistics system, ensuring seamless communication. Proximity to ports, rivers, and seas enables rapid response and efficient scheduling, storage, and transportation. This streamlined process ensures timely completion of tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are initially rolled and then redrawn to their final sizes. This method is ideal for manufacturing thick-walled, large-diameter tubes that are difficult to roll directly to size but offer significant cost savings over seamless tubes. All our stainless steel drawn tubes are bright annealed for superior quality.

Daxun Advantages

• Varieties: We offer a comprehensive range of sizes and grades, including 304L and 316L, from small to large diameter stainless steel pipes.
• Flexibility: Whether seamless or welded, our stainless steel pipes are tailored to meet your unique project requirements.
• Quality Standards: Our stainless steel pipes adhere to rigorous standards like ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring utmost reliability and performance.
• Custom Orders: Need specialized sizes? We provide a variety of stainless steel pipe customization options at competitive prices with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel tubular products are expertly drawn from hollow sections created via piercing or hot extrusion. Ideal for very large diameter to wall thickness ratios, these seamless tubes offer excellent external dimensional tolerances.

Quality, delivery, inspection

• At Daxun, we conduct a series of rigorous quality assurance tests, including flattening, pitting resistance, mechanical, hardness, material identification, and expansion tests. These tests ensure the material's suitability for its intended application.
• Throughout production, we meticulously measure the diameter, thickness, and surface of our products. Our standard delivery timeframe is 7-15 days, with special size products taking up to 20 days.
  Our delivery schedules strictly adhere to contractual agreements.
• We welcome customer-appointed third-party agencies for factory inspections.
• We provide free samples for customer testing.
• We support on-site or video factory inspections.
