Rectangular steel pipe is a common building and engineering material, usually made of steel. Its cross-section is rectangular in shape, with two different sizes of long and short sides. Rectangular steel pipe is a kind of steel that is rolled into a rectangular cross-section, which is durable and has excellent load-bearing performance.
Rectangular steel pipe is mainly composed of the following elements:
1. Steel: The main material of rectangular steel pipe is steel, usually carbon steel or alloy steel. Steel has high strength, corrosion resistance and good machinability, so that rectangular steel pipe can stably bear loads in various environments.
National standard rectangular steel pipe material grades: 20# steel, 45# steel, 16Mn, extrusion, Q345C, Q345D, Q345E, st37-2, ss400, st52-3, J55, SM490A, SM520A, ASTM A106 GR.B and other plain carbon steel, high-quality steel, alloy steel materials, etc.
Rectangular steel pipes are widely used in various fields, mainly including construction, machinery manufacturing, automobile manufacturing, aerospace, petrochemical, bridge construction, etc.
First, in the field of construction, rectangular steel pipes can be used to construct the main structure of the building, such as for the support and load-bearing of beams and columns, and can also be used for the production of building roofs, walls and floors. Rectangular steel pipes can well ensure the stability and durability of the building.
Secondly, in the field of machinery manufacturing, rectangular steel pipes are widely used to manufacture the main structure of various mechanical equipment. For example, rectangular steel pipes can be used to make parts of various mechanical equipment such as machine tools, cranes, conveyors, fans, etc., and their sturdy structure and load-bearing performance can ensure the stable operation of mechanical equipment.
In addition, in the field of automobile manufacturing, rectangular steel pipes are also widely used in the production of parts such as automobile frames, body structures, engine brackets, etc. Rectangular steel pipes have excellent strength and toughness, which can meet various mechanical requirements of automobiles during operation.
In the field of aerospace, rectangular steel pipes are used to manufacture the main structure and parts of aircraft, spacecraft and other aviation equipment. Their light and sturdy characteristics can ensure the safe operation of aviation equipment.
In the field of petrochemicals, rectangular steel pipes are mainly used in the manufacture of oil pipelines, chemical equipment and devices. Rectangular steel pipes have good anti-corrosion properties and can resist chemical corrosion and erosion in high temperature and high pressure environments.
Finally, in the field of bridge construction, rectangular steel pipes are widely used in the support structure and bridge deck construction of bridges. Rectangular steel pipes have high strength and good rigidity, which can ensure the stable operation of bridges, while also reducing the weight of bridges and improving transportation efficiency.
