1. Distinction in Production Processes
Production process for square and rectangular welded tubes: raw material preparation, uncoiling and loading, shear butt welding, material storage, leveling, forming, sizing, internal and external deburring, cooling, sizing again, sawing, inspection, packing, and stacking.
2. Distinction in Performance Characteristics
Square and rectangular welded tubes: They exhibit high structural stability and load-bearing capacity, making them suitable for applications requiring resistance to high pressure and loads. Additionally, their aesthetic and sleek appearance has led to their widespread use in the fields of architecture and decoration.
High-frequency welded round tubes: Due to the adoption of high-frequency welding technology, they offer high welding quality with weld strength close to that of the base metal. The welding process requires no additional filler metal, thereby reducing production costs. Furthermore, high-frequency welded round tubes possess excellent corrosion resistance and fatigue resistance.
3. Distinction in Application Fields
Square and rectangular welded tubes: They are widely used in construction, machinery manufacturing, bridge construction, and other fields. In the construction sector, square and rectangular welded tubes are commonly used for making beams, columns, and support structures. In machinery manufacturing, they are used for fabricating frames, brackets, and other components of various mechanical equipment.
High-frequency welded round tubes: They are primarily used in fluid transportation and structural support applications. For instance, in piping systems for water supply, drainage, gas supply, and heating, high-frequency welded round tubes serve as the main conveyance pipes. They are also commonly used in the petroleum and chemical industries for fabricating various process piping and equipment.
