Detailed Photos

At Daxun Alloys, we pride ourselves on being a leading supplier of premium stainless steel tubing that caters to a diverse range of pipe requirements. Our Type 304 stainless steel, an austenitic nickel-chromium alloy with exceptionally low carbon content, is the perfect solution for welding applications. Known as '18/8' stainless steel for its 18% chromium and 8% nickel composition, this material boasts remarkable strength, superior oxidation resistance, excellent formability, and moderate machinability. For environments demanding heightened resistance to intergranular corrosion, our 304L stainless steel variant offers enhanced immunity in the most corrosive conditions. Daxun Alloys provides both seamless and welded forms of 304 stainless steel pipes, available in a variety of diameters. We also offer precision pipe cutting services to ensure your products perfectly meet your specifications. Daxun specializes in stainless steel pipes-reach out to us today!

Stainless Steel Welded Tubes

Our stainless steel tubular products are meticulously crafted from stainless steel strips that are roll-formed and fusion-welded along the longitudinal seam. The sophisticated welding technique employed by Daxun eliminates the need for any filler metals during the process, ensuring superior integrity and quality.

Daxun offers swift and reliable delivery of 304 stainless steel pipe products, powered by a seamless integration of production capacity, information flow, logistics, and capital flow. Our advanced system pushes order data to the logistics network in real-time, ensuring data cohesion. Strategically positioned near ports, rivers, and seas, our processing centers facilitate efficient scheduling, rapid response, and coordinated storage and transportation. This system guarantees timely completion of every task.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo a meticulous rolling and re-drawing process to achieve their final size. This technique is particularly suitable for producing thick-walled, large-diameter tubes that are otherwise impractical to roll directly to size, offering significant cost savings over seamless tubes. All our stainless steel drawn tubes are bright annealed, ensuring superior quality and finish.

The Daxun Difference

• Variety: From small to large diameter pipes, our extensive range includes sizes and grades such as 304L, 316L, and more.
• Flexibility: Our stainless steel pipes, available in both seamless and welded forms, are tailored to meet your specific project requirements.
• Quality Standards: Our products adhere to rigorous standards like ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175, ensuring top-notch reliability and performance.
• Custom Orders: Need unique sizes? We offer a variety of stainless steel pipe customization options at competitive prices, with the convenience of online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are crafted from the hollow section of the tube, created through piercing or hot extrusion processes. Ideal for maintaining large diameter-to-wall thickness ratios, these tubes offer exceptional external dimensional tolerances and performance.

Assurance of Quality, Timely Delivery, and Rigorous Inspection

• Daxun conducts an array of quality assurance tests including flattening, pitting resistance, mechanical, hardness, material positive identification, and expansion tests. These tests confirm the material's suitability for various applications.
• Throughout production, we meticulously measure the diameter, thickness, and surface of our products. Standard delivery time is 7-15 days, though special size products may extend this to 20 days.
  Our delivery schedule rigorously adheres to the contractual agreements.
• We welcome third-party agencies for factory inspections on behalf of customers.
• We offer complimentary samples to customers for testing purposes.
• We support on-site or virtual factory inspections.
