Erection requirements for API standard 650 uplifting tanks

Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API standard 650 uplifting tanks 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.

Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API standard 650 uplifting tanks will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.

The ring of API standard 650 uplifting tanks annular plates shall have a circular outside circumference, but may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with API Standard 620 R.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by welds as required by API Standard 620 5.9.5 except when a full penetration weld is used or required.

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel API standard 650 uplifting tanks, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.
