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
The competitiveness of enterprises, in the final analysis, is the competitiveness of people, gathering talented people, revitalizing human resources for the "cold winter" in the business department is particularly important. In order to further improve labor efficiency and create a dynamic workforce, the Ministry of Public Services has taken the initiative to reform.

Vitality provides strong support for business improvement.
山东大鼎钢管厂钢管与圆钢等实心钢相比，无缝钢管的弯扭强度相同，重量轻。它是一种经济型钢。广泛应用于石油钻杆、汽车传动轴、自行车车架、建筑用钢脚手架等结构机械零件的制造。采用无缝钢管制造环形件，可以提高材料的利用率，简化制造工艺，节省材料和加工时间，如滚动轴承环、千斤顶套筒等。钢管也是各种常规武器不可缺少的材料，如管道、枪支等。根据截面面积的形状，钢管可分为圆形管和异型管。由于圆周相等，圆形区域大，圆管可以输送更多的流体。另外，环形截面在内外径向压力作用下，受力更加均匀，因此绝大部分钢管都是圆形的。
