Detailed Photos

Daxun Alloys stands at the pinnacle of stainless steel tubing suppliers, addressing a diverse spectrum of pipe requirements with unmatched expertise. Crafted from Type 304 stainless steel, an austenitic nickel alloy with minimal carbon content, our tubing is the epitome of welding excellence. Often referred to as '18/8' stainless steel due to its composition of 18% chromium and 8% nickel, this alloy ensures superior strength, oxidation resistance, excellent formability, and moderate machinability. For applications demanding heightened resistance to intergranular corrosion, we recommend our 304L variant, designed for the most corrosive environments. Available in both seamless and welded forms, our 304 stainless steel pipes come in an array of diameters. We also offer precision pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your premier choice for quality and reliability-contact us today to learn more.

Stainless Steel Welded Tubes

Daxun's stainless steel tubular products are meticulously roll-formed and fusion-welded from premium stainless steel strips along the longitudinal seam. Our advanced welding process is distinguished by the absence of any filler metal, ensuring a seamless finish.

At Daxun, we pride ourselves on delivering 304 stainless steel pipe products with unparalleled promptness. Our efficiency is backed by a robust system encompassing production capacity, real-time information flow, and seamless logistics and capital flows. For instance, our order data is instantly relayed to the logistics system, ensuring seamless integration. Strategically located processing centers near ports, rivers, and seas facilitate efficient scheduling, rapid responses, and synchronized storage and transportation, guaranteeing timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo a stringent rolling and re-drawing process to reach their final size. This method is perfect for producing thick-walled, large-diameter tubes that cannot be directly rolled to size, offering significant cost savings over seamless tubes. Every stainless steel drawn tube is bright annealed for optimal quality.

Daxun Advantages
