Application of Seamless Steel Pipe

　　China seamless pipeline network recently learned: a lot of classification methods. According to the manufacturing process, there are hot-rolled seamless pipe and cold-rolled seamless pipe.

　　Classified by use: seamless steel pipe for general structure, seamless steel pipe for conveying fluid, seamless steel pipe for medium and low pressure boilers, seamless steel pipe for high pressure boilers,... Hebei Shengtian Manufacturing Product  Seamless Steel Pipe,According to material classification: high quality carbon structural steel seamless steel pipe, low alloy structural steel seamless steel pipe, alloy steel seamless steel pipe. Seamless steel pipes are widely used, which can be processed into mechanical parts, used to transport liquids or gases, to drive bearings, and to build rigid structures.

　　In sheet metal, Q345B seamless steel pipe belongs to low alloy series. Among the low alloy materials, this material is the most common. Q345B seamless steel pipe used to be called 16Mn seamless steel pipe. The external execution standard of Q345B seamless steel pipe is GB709, and the internal execution standard is GB/T1591-94. Naming method similar to Q345B. Due to the implementation of the standards, such steel plates are allowed to be delivered in negative tolerances. Q345 seamless steel pipe is a kind of steel pipe material. Q stands for the yield of this material, the latter 345, that is, the yield value of this material, around 345. The yield value decreases with the increase of material thickness. Q345A, no impact; Q345B, 20 degree normal temperature impact; Q345C, 0 degree impact; Q345D, 20 degree impact; Q345E, 40 degree impact. At different impact temperatures, the impact values are also different.
