Product Description
Square tube is a name for square pipe and rectangular pipe, which is hollow pipe with equal side length and unequal side length. It is made of strip steel after processing and rolling. Generally, the strip is unpacked, leveled, crimped and welded into a round tube, which is rolled into a square tube and then cut into the required length. The commonly used welding process is arc welding square tube, resistance welding square tube (high frequency, low frequency); Products are widely used in machinery manufacturing, construction, gold industry, agricultural vehicles, agricultural greenhouses, automobile industry, railway, highway guardrail, container skeleton, furniture, decoration and steel structure fields.

Application
hollow section steel tube have a wide range of applications due to their strength, durability, and relatively low cost compared to other materials. Some common applications of carbon steel pipes include:
1.Transportation of fluids: Carbon steel pipes are often used for the transportation of fluids, such as water, oil, and gas, in pipelines. These pipes are typically used in the oil and gas industry, as well as in municipal water and wastewater systems.
2.Structural support: Carbon steel pipes are also used for structural support in construction projects, such as in the construction of buildings and bridges. They can be used as columns, beams, or braces, and can be coated or painted to protect against corrosion.
3.Industrial processes: Carbon steel pipes are used in a variety of industrial processes, such as manufacturing and transportation. They are used to transport raw materials, finished products, and waste materials.
4.Heat exchangers: Carbon steel pipes are used in heat exchangers, which are devices that transfer heat between fluids. They are commonly used in the chemical and petrochemical industries, as well as in power generation.
5.Machinery and equipment: Carbon steel pipes are used in the construction of machinery and equipment, such as boilers, pressure vessels, and tanks. These pipes can withstand high pressure and temperature, making them ideal for use in these applications.
