Detailed Photos

Daxun Alloys takes pride in being a top supplier of stainless steel tubing capable of meeting a wide range of pipe demands. Type 304 stainless steel is an austenitic nickel alloy with extremely low carbon content, making it ideal for welding applications. It is essentially an austenitic chromium alloy, sometimes known as "18/8" stainless steel because it contains 18% chromium and 8% nickel. Our 304 stainless steel pipe has exceptional strength and oxidation resistance, great formability, and moderate machinability. For applications requiring increased resistance to intergranular corrosion, we propose 304L stainless steel, which has a better immunity in severely corrosive situations. Daxun Alloys carries 304 stainless steel pipe in seamless or welded form. 304 grade pipe is offered in a range of diameters. We also provide pipe cutting services to ensure that your pipe products are the exact length you require. Daxun specialises in stainless steel pipes; contact us immediately.

Stainless Steel Welded Tubes

Stainless steel tubular products made from stainless steel strip are roll-formed and fusion-welded along the longitudinal seam. The welding process used by Daxun does not use any filler metal during the welding process.

Daxun provides you with timely and fast delivery of 304 stainless steel pipe products. Behind the speed is the system support from production capacity, information flow to logistics and capital flow. For example, in terms of information flow, Daxun's order data is pushed to the logistics system in real time, and the data is seamlessly connected; in terms of logistics, the processing center is close to ports and rivers and seas, with reasonable scheduling, rapid response, storage and transportation linkage, and efficient loading, ensuring that the task is completed on time.

 

 

Stainless Steel Drawn Tube

Stainless steel tubular products are rolled and then re-drawn to final size. Rolling and drawing is ideal for producing thick walled, large diameter tubes that cannot be rolled directly to size but still offer cost savings over stainless steel seamless tubes. All stainless steel drawn tubes are bright annealed.

Daxun Advantages

• Varieties: From small to large diameter stainless steel pipes, we offer a wide range of sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether you need seamless or welded steel pipes, our stainless steel pipes can meet your specific project requirements.
• Quality Standards: Our stainless steel pipes meet stringent standards such as ISO9001, ABS, NSF/ANSI Standard 61, and NACE MR0175 to ensure reliability and performance.
• Custom Orders: Looking for special sizes of stainless steel pipes? We offer a variety of stainless steel pipe customization options at competitive prices and convenient online ordering.

 

Stainless Steel Seamless Tube

Stainless steel tubular products are drawn from the hollow section of the tube, which is made by piercing or hot extrusion processes. Stainless steel seamless tube is ideal for very large diameter to wall thickness ratios and has very good external dimensional tolerances.

Quality, delivery, inspection

• Daxun also conducts several quality assurance tests. These tests include flattening test, pitting and resistance test, mechanical test, hardness test, material positive identification, expansion test, etc. All these tests ensure that the material is suitable for the required application.
• During the production process, we measure the diameter, thickness, and surface of the product. Our standard delivery time is 7-15 days, except for some special size products, our delivery time will increase to 20 days.
  Our delivery time is strictly in accordance with the contract.
• Support customer third-party agencies to go to the factory for inspection
• Support free samples to customers for testing
• Support on-site or video factory inspection
