5254 aluminum tube API 650 mechanically-anchored steel tanks
The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API 650 mechanically-anchored steel tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
Stamping of API 620 storage tank PlatesBefore plates required to be stamped by the steel mill are used, the inspector shall see that they bear the stamp. In laying out and cutting the API 650 mechanically-anchored steel tanks plates, at least one set of the original material identification markings should, if possible, be left where it will be plainly visible when the tank is completed. Should the identifying marks be obliterateSpot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API 650 mechanically-anchored steel tanks. Closed cleaning is adopted for mechanical cleaning. During the cleaning process, operators are not required to enter the tank. The inert gas space formed in the storage tank can prevent the occurrence of fire, explosion and other accidents. When the API 650 mechanically-anchored steel tanks is manually cleaned, the operators should directly enter the tank for cleaning, threatening the health of employees, and there is no inert gas space in the tank, which is prone to fire and explosion accidents.
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API 650 mechanically-anchored steel tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API 650 mechanically-anchored steel tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API 650 mechanically-anchored steel tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
