API 650 SUG II tanks welding requirements

Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API 650 SUG II tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.

The API 650 specification provides guidelines for the API 650 SUG II tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.

Good news: In May 17th, 2018, the Myanmar navy's local representative visit our office and hot rolled plate production line, and sign another contract 2025 tons LR A shipbuilding steel plates API 650 SUG II tanks order in our office. With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon cooperated with Myanmar Navy company from from 2015. They purchased 412 ton LR AH36 ship steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly.

Prefabricating API 650 SUG II tanks components before construction can improve construction efficiency, save time and cost, and is currently a common method for the construction of large vertical storage tanks. The main prefabricated components of a large vertical API 650 SUG II tanks include the tank body, the storage tank wall, the top of the storage tank, the bottom of the storage tank, and the accessories of the storage tank. The prefabrication of the components should follow a reasonable workflow, and carry out appropriate heat treatment and testing, so as to improve manufacturing accuracy.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
