Alloy steel tubes have hollow sections and are used extensively as pipelines for conveying fluids, such as pipelines for oil, gas, gas, water and certain solid materials. Compared with solid steel such as round bar, alloy steel pipe has a relatively light weight in flexural and torsional strength, and alloy steel pipe is an economical section steel, which is widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, Alloy Steel Pipe and Tube automobile propeller shaft, bicycle frame and steel scaffold used in construction. Making annular parts with alloy steel pipe can improve material utilization, simplify manufacturing process, save material and working hours, such as rolling bearing rings, Jack sets, etc., which are now widely used in alloy steel pipes. Alloy steel pipe or a variety of conventional weapons indispensable materials, barrel, barrel, etc. to be made of alloy steel pipe. Alloy steel pipe According to the cross-section of the shape of the different area can be divided into round pipe and shaped tube. Alloy Steel Pipe and Tube As the circumference is equal, the circle area is the largest, and more fluids can be transported with a circular tube. In addition, the ring section under the internal or external radial pressure, the force is more uniform, so most of the alloy steel pipe is round pipe.

Alloy steel pipes are not only used for conveying fluids and powdered solids, exchanging heat, making mechanical parts and containers, it is also an economic steel. The use of alloy steel pipe to manufacture structural frame, pillar and mechanical bracket can reduce the weight, save metal $number, and can realize the mechanization construction of factory.

The manufacture of highway bridges with alloy steel pipes can not only save steel and simplify construction, but also reduce the area of coating layer and save investment and maintenance cost. Therefore, Alloy Steel Pipe and Tube any other type of steel can not completely replace the alloy steel pipe, but the alloy steel tube may replace some sections and rods. Alloy steel Pipe has a great relationship with the development of national economy and the quality of human life, which is much better than other steel. From the people's Daily utensils, furniture, Alloy Steel Pipe and Tube water supply and drainage, gas, ventilation and heating facilities to a variety of agricultural equipment manufacturing, underground resources development, defense and aerospace use guns, bullets, missiles, rockets, etc. are inseparable from the alloy steel pipe.

Alloy steel tubes are widely used. General-purpose carbon structural steels, low alloy structural steel or alloy structural steel rolling, the most output, mainly used for conveying fluid pipeline or structural parts according to the use of different three types of supply: A, according to chemical composition and mechanical properties of supply; b, according to mechanical performance supply; b supply, Alloy Steel Pipe and Tube if used to withstand liquid pressure, but also to carry out water pressure tests. Special purpose for boiler, geology and petroleum use and so on. According to the different production methods can be divided into hot-rolled pipe, cold rolling pipe, cold drawn pipe, extruded pipe and so on. According to the shape of the classification has a circular tube, special-shaped tube. The special-shaped tube except the square tube and the rectangular tube, but also semicircular tube, triangular tube, hexagonal tube, convex shape tube, plum-shaped tube and so on.
