Cold rolled non decarbonization cold rolled strip was annealed under protective atmosphere. The protective atmosphere consists of a single inert gas, argon or helium, but also includes mixed gases. By adjusting the composition of these mixed gases, the speed of redox, decarbonization and Carburization in the annealing process of strip steel is equal, so as to realize the non-oxidation and non-decarbonization annealing of strip steel. After annealing, bright precision tubes should be decarburization. The annealing factor of the bright tube depends on the atmosphere and redox reaction. And other inert gases are neutral protective atmospheres of steel. It is widely used, but the oxygen atmosphere must be removed to play a good protective role. Commonly used mixed protective atmospheres.结构用无缝钢管（GB/T8162-2008）是用于一般结构和机械结构的无缝钢管。流体输送用无缝钢管（GB/T8163-2008）是用于输送水、油、气等流体的一般无缝钢管。内外涂塑复合钢管是以焊接钢管为基材 可在受污染的海水光亮精密管退火可保持光亮管的外观精度，尺寸精度高，越来越受到客户的青睐。
山东大鼎钢管厂Seamless steel pipe is mainly produced by hot rolling, and extrusion method is mainly used to produce low plasticity high alloy steel pipe or special-shaped steel pipe and composite metal pipe which is difficult to pierce. Cold rolling and cold drawing process can make hot rolled tubes into small diameter thin-walled steel tubes. Welding steel pipe technology is simple, high production efficiency, low cost, and product variety is expanding day by day. Inventory or inventory increases capital risk. Tool Rust Removal: It is mainly used to grind steel surface with wire brush and other tools. It can remove loose or convex oxide scale, rust, welding slag and so on.山东大鼎金属材料有限公司
电动工具除锈可达到Sa级，如果钢表面粘附有固体氧化皮，不能满足建筑施工中保温和防腐施工线深度的要求。无缝钢管一般由优质碳素结合钢16Mn、5MnV、低合金结构钢40Cr、30CrMnSi、45Mn2、40MnB等合金钢经热轧或冷轧制成。低碳钢制成的无缝管主要用于流体输送管道。用45和40Cr等中碳钢制成的无缝管用于制造汽车和拖拉机等机械零件。一般来说，要保证无缝钢管的强度和扁平度。热轧钢管是在热轧或热处理中输送的，冷轧是在热处理中进行的。两个过程综述热轧（挤压无缝钢管）：圆坯加热穿孔三辊横轧、连续轧制或挤压汽提定径（或减径）冷却坯管矫直水压试验（或探伤）标记储存。
The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
