API Std 650 low-alloy steel tanks intermediate wind girders

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API Std 650 low-alloy steel tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API Std 650 low-alloy steel tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

Natural ventilation loss: the main cause of natural ventilation loss is that the API Std 650 low-alloy steel tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API Std 650 low-alloy steel tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.

Production Weld Tests
Production weld test plates shall be welded for API Std 650 low-alloy steel tanks 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.

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

The mode of iron and API Std 650 low-alloy steel tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API Std 650 low-alloy steel tanks steel logistics.
