Main causes of subsurface bubble formation in JIS SM400C plates

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the JIS SM400C plates steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of JIS SM400C plates seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Pipeline steel JIS SM400C plates is mainly used for the transportation of oil and natural gas. Pipeline steel (LPS) is mainly used for processing and manufacturing oil and gas pipelines. Oil and gas pipeline network is the most convenient and safe channel connecting the resource area and market area. Its rapid construction will not only relieve the pressure of railway transportation, but also help to ensure the safe supply of oil and gas market and improve the level and capacity of energy security.
