API Std 650 self-anchored tanks joints
The API 650 petroleum storage tank standard is one of the most widely used design specifications. It is the API 650 standard of the American Petroleum Institute. The main goal of the API 650 standard is to promote the purchase and construction of vertical, above-ground, and welded manufacturing API Std 650 self-anchored tanks tanks through the requirements contained in its parts to ensure that the required safety regulations are met.
There is no dome roof in the top of the vertical external floating roof oil storage tank, only the disc floating roof which can float up and down. The wall plates are connected by butt welding, and the construction is usually carried out by the forward installation method, and the storage capacity is usually more than 10000 cubic meters. Vertical internal floating roof API Std 650 self-anchored tanks has both dome roof and internal floating roof. The internal floating roof floats on the liquid surface inside the dome roof oil tank and can float up and down. The storage capacity is usually between 1000 and 10000 cubic meters.
In this project, an area of steel storage oil tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2.
Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API Std 650 self-anchored tanks service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
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 self-anchored 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 self-anchored 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.
