The company specializes in the research and development, production and sales of EN10025-4 S460ML steel price seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has EN10025-4 S460ML steel price five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,EN10025-4 S460ML steel price rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

If you have any requirements for the mode of transportation of the EN10025-4 S460ML steel price goods, we can also negotiate and meet your requirements. For logistics, first of all, we respect customers' opinions, and then choose the most convenient port and transportation mode with appropriate price for customers.

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 EN10025-4 S460ML steel price 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 EN10025-4 S460ML steel price seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

This customer is a leading Engineering, Procurement and Construction company serving the Hydrocarbon and Chemical industries spanning Oil & Gas, Petrochemical, Refining, Fertilizer and related sectors in India. The A335 Grade P5 Steel Pipe and P9 EN10025-4 S460ML steel price Seamless Steel Pipe we supplied is for EIL refineries project.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of EN10025-4 S460ML steel price, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
