The development of Steel pipe (STEELPIPE) production technology began in the rise of bicycle manufacturing, the development of oil in the early 19th century, the manufacture of ships, boilers and aircraft during World War Two, the manufacture of thermal power boilers after World War II, Steel Pipes the development of chemical industry and the drilling and transportation of oil and gas, All powerfully promote the development of steel pipe industry in variety, yield and quality.
The steel pipe is not only used for conveying fluid and powdery solids, exchanging heat, making mechanical parts and containers, it is also an economic steel. Using steel tube to make structure truss, pillar and mechanical bracket can reduce weight, save metal $number, Steel Pipes and realize factory mechanized construction. The use of steel pipe to make highway bridges can save steel and simplify construction, and can greatly reduce the area of coating layer and save investment and maintenance cost.
Steel Pipe Classification
The steel tube can be classified according to the rolling process, whether there are joints and the shape of section. According to the rolling technology classification, the steel pipe can be divided into hot-rolled steel pipe and cold rolled steel pipe; Steel Pipes According to whether there is seam classification, steel pipe is divided into seamless steel pipe and welded steel pipe, which are commonly used welded pipe types can be divided into high-frequency welded pipe, straight seam submerged arc welded pipe, spiral submerged
The steel pipe has a hollow section and is used as a conduit for conveying fluids, such as pipelines for oil, gas, gas, water and some solid materials. Steel pipe and round steel, such as solid, in the flexural and torsional strength of the same time, light weight, is an economic section of steel, Steel Pipes widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile propeller shaft, bicycle racks and construction of steel scaffolding, etc. The use of steel tubes to make ring parts, can improve the utilization of materials, simplify manufacturing processes, saving materials and processing hours, such as rolling bearing rings, Jack sets, etc., has been widely used steel pipe to make. Steel pipe or a variety of conventional weapons indispensable materials, barrel, barrel, etc. to be made of steel pipe. The different shape of the cross-section of the steel pipe can be divided into round pipe and shaped tube. As the circumference is equal, the circle area is the largest, Steel Pipes 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 pipe is round pipe.
