The seamed steel tube known as stainless steel welded tube undergoes a production process that involves shaping the tube blank, made of steel plate or steel strip, into the desired cross-sectional shape and dimensions using various forming techniques. Subsequently, the weld seam is created through different welding methods, resulting in the formation of a sturdy and enduring steel tube. The remarkable feature of stainless steel welded tubes lies in their exceptional resistance to corrosion, enabling them to withstand the detrimental effects of most chemical substances. These tubes also exhibit remarkable stability and durability. Moreover, welding stainless steel tubes endows them with outstanding mechanical properties, such as high strength, hardness, and toughness. Additionally, their flexibility allows for easy fabrication into tubes of diverse shapes and sizes.

Chemical Composition of Stainless Steel Welded Tube

Stainless Steel Welded Tube Mechanical Properties

Welded Stainless Steel Tube Production Process

Stainless steel 304 welded tube is made by rolling stainless steel strip or sheet into tube shape, and then welded longitudinally. Welded tubing can be done by hot forming and cold forming process. Of the two, cold forming results in smoother finishes and tighter tolerances. However, each method produces a durable, strong, corrosion-resistant steel tube. Seams can be left beaded or further processed by cold rolling and forging methods. SS welded tubes can also be drawn like seamless tubes to produce finer welds with better surface finish and tighter tolerances. At the same time, the mechanical performance, process performance, chemical composition and compressive performance of the welded tube can basically meet the national standard of seamless tube.
