09cupcrni-a steel coil sheet

Our company was founded in 2000, which initially committed to providing high-quality steel 09cupcrni-a steel coil products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export 09cupcrni-a steel coil steel to the international market, opening up the international steel market.

API 5CT Casing pipes 09cupcrni-a steel coil supplied by BBN is mostly used in well structure building. Good quality API 5CT casing pipe could ensure well structure stability, isolate water and sand from tube working area, so drilling, oil production and other operations can be taken with no contamination. We can provide 09cupcrni-a steel coil you conductor casing pipe, surface casing pipe, intermediate casing pipe, production casing pipe.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate 09cupcrni-a steel coil has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts

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 09cupcrni-a steel coil 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 09cupcrni-a steel coil seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of 09cupcrni-a steel coil, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
