Under-bottom connections for API Std 650 stainless steel storage tanks
There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 stainless steel storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 stainless steel storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.
When the API Std 650 stainless steel storage tanks is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API Std 650 stainless steel storage tanks is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.
For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API Std 650 stainless steel storage tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.
After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us
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 Std 650 stainless steel storage 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 Std 650 stainless steel storage 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.
