Seamless steel pipe refers to the steel pipe made of a whole piece of metal without joints on the surface. According to the production method, it can be divided into hot rolling tube, cold rolling tube, cold drawing tube, A514 Gr J alloy steel plate, extrusion tube and spinning tube. According to the shape of the section, it can be divided into two types: circular and irregular. The seamless tube has a maximum diameter of 650 mm (expanding tube) and a minimum diameter of 0.3 mm (capillary tube), which can be divided into thick walled tube and thin walled tube according to the thickness.
The A283 C mild steel plate comes from the carbon steel which has a low carbon alloy. The mild steel plate/carbon steel plate is a combination of a low amount of chromium, and molybdenum with low carbon as well. Because of the low carbon alloy, it is more weldable, ductile rather than the carbon steel. The mild steel plate A514 Gr J alloy steel plate is created magnetic and has a high amount of ferrite and iron. Mild steel has various characteristics like affordability, easy to weld, machinability.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for A514 Gr J alloy steel plate pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common A514 Gr J alloy steel plate carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
