Seamless steel pipes are widely used + widespread.
1. The seamless steel pipe for general purpose is rolled by ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, with the largest output, and is mainly used as a pipeline or structural part for transporting fluids.
2. It is divided into three categories according to different uses**
a. According to chemical composition and mechanical properties**;
b. According to mechanical properties**;
c. Press the water pressure test**. According to the steel pipe of class A and B**, if it is used to withstand liquid pressure, it is also necessary to carry out a hydrostatic test.
From 635x4.5. From the perspective of the seamless steel pipe market mentality, the international capital market has experienced the previous **, and after the joint introduction of the bailout and response plan by various countries this week, there has been a **. The overall market panic will also gradually subside, and the market will tend to be more retrospective and rational. The influence of the international capital market on the domestic market will be weakened, and the operation of the market will rely more on its own strength. This week's trend has diverged. It will have a greater impact on China's exports, and at the same time, it will also have a greater impact on the exports of downstream mechanical and electrical products. The domestic policy of stabilizing economic growth will bring more demand for construction steel. The market impact in the later stage will change from expectation to reality.
Next week, the manufacturing PMI index will be released, and how the data will trigger the nerves of the market. On the whole, the expectation of the steady growth policy has gradually become a reality, and the number of points that can be speculated has gradually decreased, and the current domestic 635x4.5. The current situation of supply and demand of seamless steel pipes is still relatively severe, and the market is more likely to maintain a slight weakness.
