What is API 5L seamless steel pipe?
API 5L Seamless steel pipe production methods can be divided into: Hot-rolled seamless line pipe, Cold drawn (rolled) pipe and pipe, Thermal expansion pipe, Cold spinning pipe and Squeeze pipe. Seamless steel pipe is to pump out the ground oil, steam, water, through the pipeline pipeline transmission to the oil and natural gas industry enterprises. Pipeline pipe includes seamless pipe and welded steel pipe, the pipe end has a flat end, threaded end and socket end; The connection mode is welding, collar connection, socket connection and so on. Steel grades of seamless steel pipes : GR.B, X42, X46, 52, X56, X60, X65, X70, etc.
With the development of API 5L seamless steel pipes technology and the progress of molding and technology, the application scope of API 5L seamless pipe is gradually expanding, especially the advantages of API 5L large-diameter seamless pipe are more obvious. Coupled with the cost factor, API 5L seamless pipe has occupied a dominant position in the field of pipeline steel pipe

Application of API 5L seamless steel pipe:
API 5L seamless steel pipe with hollow cross section, a large number of used for conveying fluid pipelines, such as oil, natural gas, water and some solid materials pipeline. Seamless steel pipe is a kind of economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and construction of steel scaffolding, etc. Using steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack covers, etc. At present, it has been widely manufactured with steel pipes. Steel pipe is also an indispensable material for all kinds of conventional weapons. Gun barrel and barrel are made of steel pipe. Steel pipe can be divided into round pipe and special pipe according to the different shape of cross-sectional area. Since a circle has the largest area when the circumference is equal, more fluid can be transported with a circular pipe.
In addition, the circular section under internal and external radial pressure, the force is more uniform. Therefore, the vast majority of steel pipes are round pipes. However, the circular pipe also has certain limitations. For example, under the condition of equal plane bending, the circular tube is not as strong as the square pipe and the rectangular pipe. Some agricultural machinery and tools skeleton, steel and wood furniture are commonly used square pipe and rectangular pipe. According to the different uses also need to have other section shape special-shaped steel pipe.
