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 A572 grade 42 high strength steel 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 A572 grade 42 high strength steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe A572 grade 42 high strength steel for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.
EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM.
