1. Distinction in Production Processes
Production process for square and rectangular welded tubes: raw material preparation, loading and uncoiling, shear butt welding, material storage, leveling, forming, sizing, internal and external deburring, cooling, secondary sizing, cutting, 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 significant pressure and load resistance. Additionally, their aesthetically pleasing appearance has led to their widespread use in construction and decoration fields.
High-frequency welded round tubes: Due to the high-frequency welding process, they boast high welding quality with weld strength close to the base metal. The welding process requires no additional filler metal, 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 industry, they are commonly used to make beams, columns, and support structures. In machinery manufacturing, they are used to make frames, brackets, and other components of various mechanical equipment.
High-frequency welded round tubes: They are primarily used for fluid transportation and structural support. For instance, in water supply, drainage, gas supply, and heating pipeline systems, high-frequency welded round tubes serve as the main transportation pipes. In the petroleum and chemical industries, they are also commonly used to make various process pipes and equipment.
