API standard 650 mechanically-anchored tanks qualification of welding procedures
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API standard 650 mechanically-anchored tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.
According to the standard of head of API standard 650 mechanically-anchored tanks, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API standard 650 mechanically-anchored tanks head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.
Responsibility of API 620 storage tanks ExaminerThe inspector shall ensure that all materials used in tanks constructed according to the rules in this standard comply in all respects with the requirements of these rules. This shall be done either by witnessing mill tests or examining certified mill test reports supplied by the Manufacturer. Storage tanks API standard 650 mechanically-anchored tanks constructed according to the rules in this standard shall be inspected and tested in accordance with the sections that follow. The inspector shall carefully follow the fabrication and testing of each tank and shall make sure that they comply in all details with the design, fabrication, and tests specified in these rules.
The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality API standard 650 mechanically-anchored tanks, efficient and fast services. Facing the future, adhere to independent innovation.
Steel transportation because of the special material of API standard 650 mechanically-anchored tanks steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
