API standard 650 self-anchored flat-bottom tanks metal-seated ball valve

The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API standard 650 self-anchored flat-bottom tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.

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.

When the day light gradually decreases, the temperature of oil in the API standard 650 self-anchored flat-bottom tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API standard 650 self-anchored flat-bottom tanks will also decrease. When the pressure in the API standard 650 self-anchored flat-bottom tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API standard 650 self-anchored flat-bottom tanks through the open vacuum valve, which is the "suction" process of the oil tank.

The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.

The company's logistics department has the ability to monitor the whole process of logistics. We monitor the goods in transit through advanced information technology and communication technology, timely discover and handle problems in the transportation process, and ensure the steel materials are delivered to the destination in a timely and safe manner. The professional logistics team provides powerful support for good comments of customers and good reputation of the company.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
