Structural steel for bridges is mainly used to make riveted and bolted welded bridge steel structures such as highway bridges, railway bridges, sea-crossing bridges, overpasses, viaducts, and large mechanical bridge cranes. A709 grade HPS70W bridge steel plate, E grade bridge steel is suitable for low temperature and severe cold environment or bridge structural parts that are subjected to dynamic loads and the stress conditions of components are very complex and harsh.
From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. A709 grade HPS70W bridge steel plate, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, A709 grade HPS70W bridge steel plate tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
