Steel Pipe With Anti-corrosion Characteristics

- Aug 19, 2020-

There are fundamental classes of things that have an effect on the nice of metal pipes: metal and rolling system elements.


Only the elements of the rolling system are mentioned here. The most important influencing elements are: temperature, system adjustment, device nice, system cooling and lubrication, and elimination and manipulate of particles at the floor of the rolled product.


(1) Temperature


Temperature is the maximum crucial element affecting the nice of metal pipes. First, the uniformity of the heating temperature of the tube clean at once influences the uniform wall thickness and internal floor nice of the perforated capillary tube, after which influences the wall thickness nice of the product. Secondly, the temperature and uniformity of the metal tube for the duration of rolling (specifically the very last rolling temperature) are associated with the mechanical properties, outer diameter and different dimensional accuracy and floor nice of the goods brought withinside the warm rolled state, specifically whilst the metal billet or tube billet is overheated or maybe Overburning can purpose waste. Therefore, withinside the manufacturing system of warm-rolled seamless pipes, heating and controlling the deformation temperature strictly in keeping with system necessities have to be finished first.


(2) Process adjustment


The system adjustment and the nice of labor specifically have an effect on the geometry and look nice of the metal pipe.


For example, the adjustment of the punching system and the pipe rolling system influences the wall thickness accuracy of the product, and the adjustment of the sizing system is associated with the outer diameter accuracy and straightness of the product. In addition, the system adjustment additionally influences whether or not the rolling system may be achieved normally.


(3) Tool nice


The nice of the device is ideal or bad, and whether or not it's far strong or now no longer is at once associated with the powerful manipulate of the dimensional accuracy and floor nice of the product and the intake of the device; The 2nd is to have an effect on center rod intake and manufacturing costs.


(4) Process cooling and lubrication


The cooling nice of the perforated head and roll now no longer handiest influences its life, however additionally influences the inner and outside floor nice manipulate of the completed product. The cooling and lubricating nice of the center rod first influences the internal floor nice, wall thickness accuracy and center rod intake of the metal pipe; on the identical time, it's going to additionally have an effect on the weight for the duration of rolling.


(5) Removal and manipulate of particles at the floor of rolled products


This refers back to the well timed and powerful elimination of iron oxide scales at the internal and outer surfaces of capillaries and waste pipes and the manipulate of re-oxidation earlier than rolling deformation. Nitrogen blowing and borax spraying at the internal hollow of the capillary tube, excessive-strain water descaling at the doorway of the rolled tube and the fixed (reduced) diameter can successfully enhance and enhance the inner and outside floor nice.


In short, the elements that have an effect on the nice of metal pipes are multifaceted, and frequently a aggregate of numerous elements. Therefore, the above-referred to most important influencing elements have to be successfully managed. Only on this manner can the nice of metal pipes be managed and warm-rolled seamless metal pipes with excessive dimensional accuracy, desirable overall performance and desirable nice produced.
