EN S355J0 plates API Std 650 cylindrical liquid-storage tank

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API Std 650 cylindrical liquid-storage tank and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1. After the tank is filled with water and before the pneumatic pressure is applied, anchorage, if provided, shall be tightened against the hold-down brackets. All welds in the API Std 650 cylindrical liquid-storage tank shell, including the corner weld between the shell and the bottom, shall be visually checked for tightness.API 650 is an American standard for welding flat bottom vertical storage tanks. This API Std 650 cylindrical liquid-storage tank standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API Std 650 cylindrical liquid-storage tank crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for API Std 650 cylindrical liquid-storage tank iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.Requirements for prefabrication of bottom plate of large vertical API Std 650 cylindrical liquid-storage tank:
1. The diameter of tank bottom should be enlarged by 0.1% ~ 0.15% according to the design diameter.
2. The minimum dimension of edge plate along the radius direction of tank bottom shall not be less than 700mm.
3. The distance between any adjacent welds of the base plate shall not be less than 300 mm.
