Seamless Round Tube

Stop

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.

Application field

Stainless steel plate is a more general choice. It's used in the construction of ships and storage containers, including manufacturing and construction. Stainless steel plate are also widely used in construction projects, including bridges, ships, and even various types of commercial and municipal buildings. Due to the strength provided by Stainless steel , steel plates can be used to manufacture various supports and supports, which are part of the overall structural design.
