API 650 ground supported flat-bottom tanks joint penetration

As we know, the vertical metal tank, API 650 ground supported flat-bottom tanks is welded by many components, and the welding quality of each component determines the later use effect of the API 650 ground supported flat-bottom tanks. Professional API 650 ground supported flat-bottom tanks manufacturers should have a set of professional skills in the welding process of API 650 ground supported flat-bottom tanks. Key points for weld inspection of vertical metal tank, API 650 ground supported flat-bottom tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.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 ground supported flat-bottom 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.For floating roof API 650 tanks, the net working capacity is the liquid volume contained between the API 650 ground supported flat-bottom tanks maximum operating level (300 mm below rim for metallic type seals and 600 mm below rim for fabric type seals) and the minimum operating level (API 650 tanks roof supports clearing the tank bottom by 25 mm while set at the operating position).The company revolves around the long-term strategy of "building a quality base and building a century-long BEBON", adheres to the development ideas of innovation, transformation, and improvement, vigorously promotes transformation and upgrading, structural adjustment, energy conservation and emission reduction, and strives to create high-quality steel with strong core competitiveness and distinctive features The production base has become a green steel city with intensive land use, clean production, efficient use of resources, harmonious and friendly production and environment, business and society, and BEBON characteristics.The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate API 650 ground supported flat-bottom tanks after-sales service to customers.
