The bearing capacity of LSAW (Longitudinal Submerged Arc Welded) steel pipes depends on two main factors. First, the mechanical properties of the steel, which include the yield point, tensile strength, elongation, and impact toughness. Second, the geometrical characteristics of the pipe's cross-section play a significant role. Typically, circular straight welded pipes offer the strongest resistance to local buckling, making them the most efficient at withstanding both radial internal and external pressures.
For pipes with the same steel grade, cross-sectional area, and support conditions, rectangular or slanted steel pipes exhibit stronger eccentric compression resistance. Meanwhile, circular and square steel pipes have the highest compressive bearing capacity. However, square and rectangular LSAW steel pipes are more prone to local buckling compared to circular pipes, due to their reduced ability to resist such forces.
In comparison to LSAW steel pipes, seamless steel pipes have a more complex manufacturing process, higher quality, and greater cost, which makes them less commonly used in engineering applications. LSAW pipes, on the other hand, are more widely applied.
Currently, LSAW steel pipes combine the advantages of both seamless and welded pipes. This design allows the pipe to withstand lateral compression and significantly enhances its compressive strength. Additionally, the presence of the straight seam increases the pipe's rigidity, and when combined with the inherent characteristics of the steel, this results in a substantial improvement in bearing capacity.
