Large-diameter square pipe refers to a rectangular cross-section pipe with a large diameter or side length. They are commonly used in engineering fields such as building structures, bridges, industrial piping systems, etc. The size of large-diameter rectangular pipe usually exceeds the specification range of conventional rectangular pipe.
Square pipes are usually made of steel or other metallic materials to provide enough strength and rigidity to support heavy loads. These pipes can be fabricated by welding, bending of steel plates, etc. to meet specific engineering requirements.
In building structures, large-diameter square tubes are often used in beams, columns, frames, etc. to support and transmit gravity loads and lateral loads. In industrial piping systems, rectangular pipes can be used to convey liquids, gases, or other fluid media, and as structural supports.
Large-diameter square tubes have high load-bearing capacity and rigidity and can meet engineering projects that require large spans or high loads.
