For environments demanding superior intergranular corrosion resistance, our 304L variant offers enhanced protection in highly corrosive conditions. Available in both seamless and welded forms, our 304 stainless steel pipes come in various diameters and can be cut to your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to source for high-quality, reliable piping solutions. Contact us today!

Stainless Steel Welded Tubes

Our premium stainless steel tubular products are meticulously crafted from stainless steel strip, roll-formed, and fusion-welded along the longitudinal seam. The advanced welding technology employed by Daxun ensures no filler metal is used, guaranteeing top-notch quality.

Daxun ensures prompt and efficient delivery of 304 stainless steel pipe products, supported by a robust system encompassing production capacity, information flow, logistics, and capital flow. Real-time order data integration with our logistics system, strategic proximity of processing centers to ports and waterways, and synchronized scheduling all contribute to our fast, reliable service. Our efficient storage, transportation linkage, and swift loading ensure timely completion of your orders.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and re-drawing to achieve their final size. This process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering cost savings over seamless options. All drawn tubes are bright annealed to ensure superior quality.

Daxun Advantages

• Varieties: We offer an extensive range of stainless steel pipes, from small to large diameters, in various grades including 304L, 316L, and more.

• Custom Orders: For unique size requirements, we offer a variety of customization options for stainless steel pipes, coupled with competitive pricing and convenient online ordering.

 

Stainless Steel Seamless Tube

Our seamless stainless steel tubular products are derived from the hollow section of the tube, created through piercing or hot extrusion methods. Ideal for large diameter-to-wall thickness ratios, these tubes boast exceptional dimensional accuracy.

Quality, delivery, inspection

• Daxun conducts rigorous quality assurance tests, including flattening, pitting resistance, mechanical, hardness, material identification, and expansion tests. These stringent tests ensure the material's suitability for its intended applications.
• Throughout production, we meticulously measure the diameter, thickness, and surface of our products. While our standard delivery time ranges from 7-15 days, special size products may extend the delivery period to 20 days.
  Our delivery commitments are strictly adhered to as per the contract.
