Seamless Square Tube

Seamless steel pipes are round, square, or rectangular steel tubes with a hollow section and no joints. They are made from steel ingots or solid tube blanks through a perforation process to create capillaries. These capillaries are then hot-rolled, cold-rolled, or cold-drawn to form seamless steel pipes. The seamless steel pipe\'s hollow section makes it suitable for various applications, especially as a pipeline for fluid conveyance. Compared to solid steel, such as round steel, seamless steel pipes have a lighter weight while maintaining equivalent bending and torsional strength. This characteristic makes them an economical choice for structural parts and mechanical components. They are widely used in various industries, including the manufacturing of oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.
