Characteristics of hot rolled seamless steel pipe

　　Hot rolled seamless steel pipe are divided into ordinary steel tubes, low and medium pressure boiler pipe, high pressure boiler pipe, alloy steel pipe, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..

　　The advantages of hot-rolled seamless steel pipe can destroy the casting structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the API 5L X52 Seamless steel pipe structure is compact and the mechanical properties are improved. This improvement is mainly reflected along the rolling direction, so that steel is no longer a certain extent, isotropic body; casting formed when bubbles, cracks and loose, can also be welded under high temperature and pressure.
