27m diameter API Std 650 cylindrical liquid-storage tank

The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!Production Weld Tests
Production weld test plates shall be welded for API Std 650 cylindrical liquid-storage tank primary-component butt-welded shell plates when welding procedure qualifications are required to be impact tested per Q.6.2 and Q.6.3. The number of production weld tests shall be based on the requirements of Q.6.6.3 and Q.6.6.4. The locations impact tested (i.e., HAZ and/or weld deposits) shall likewise be the same as required for weld procedure qualifications per Q.6.2 and Q.6.3. Weld testing shall be in accordance with Q.6.6.5. Test plates shall be made from plates produced only from the heats that are used to produce the shell plates for the large welded steel tank.Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API Std 650 cylindrical liquid-storage tank floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API Std 650 cylindrical liquid-storage tank leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API Std 650 cylindrical liquid-storage tank during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.
