ASTM A573 plates API Std 650 SUG I 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 Std 650 SUG I 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.

All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API Std 650 SUG I tanks, the consumption of API Std 650 SUG I tanks is different, so it should be taken into account when evaluating the remaining service life of API Std 650 SUG I tanks.

Test plates shall be welded using the same qualified welding procedure and electrodes that are required for the tank shell plate joints. The API 620 steel storage tank test plates need not be welded as an extension of the tank shell joint but shall be welded in the required qualifying positions. One test weld shall be made on a set of plates from each specification and grade of API Std 650 SUG I tanks plate material, using a thickness that would qualify for all thicknesses in the shell. Each test welded of thickness t shall qualify for plate thicknesses from 2t down to t/2, but not less than 5/8 in. For plate thicknesses less than 5/8 in., a test weld shall be made for the thinnest shell plate to be welded; this test weld will qualify plate thicknesses from t up to 2t.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API Std 650 SUG I tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API Std 650 SUG I tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
