API Std 650 welded storage tanks welding methods

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 welded storage 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.

The coating on the outer wall of API Std 650 welded storage tanks can not only reflect light but also prevent corrosion. Different coatings for oil tanks have different reflective properties, and the reflective performance of coatings is expressed by reflection index. For example, the reflection index of white coating is 90.0, that of sky blue coating is 85.0, and that of light gray coating is 57.0. It can be seen that the white coating has good reflective performance, and coating the outer surface of API Std 650 welded storage tanks with white coating can reduce the evaporation consumption of the oil tank.

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 welded storage 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.

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, API Std 650 welded storage tanks and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

The mode of iron and API Std 650 welded storage 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 welded storage tanks steel logistics.
