Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, A709 Gr 50 low alloy steel sheet etc. are common pressure vessel steel grades.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the A709 Gr 50 low alloy steel sheet, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
We have new significant A709 Gr 50 low alloy steel sheet projects in Nigeria. It is about crude oil storage tanks. With the development of our steel materials business in the Africa those years, Nigeria has been an important market to us. And we have many A709 Gr 50 low alloy steel sheet famous projects in local and also participated in a lot of governmental projects. This crude oil storage tanks project is a very big engineering, and lasts for years. This is the only initial stage. We are under negotiation about following installation and further demands etc. matters.
Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, A709 Gr 50 low alloy steel sheet and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.
Due to the high cost support of raw material end and the re attack of environmental protection and production restriction of steel enterprises, the market supply is limited and A709 Gr 50 low alloy steel sheet traders are willing to support the price. However, the influence of off-season continues, the terminal demand is greatly reduced, and the downstream merchants mainly purchase on rigid demand. The overall delivery performance is not good. It is expected that the A709 Gr 50 low alloy steel sheet price will be adjusted steadily tomorrow.
