API standard 650 larger diameter tanks for elevated temperature service

The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API standard 650 larger diameter tanks but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.

API 650 storage tanks API standard 650 larger diameter tanks are only suitable for containers that can evenly support the entire bottom and containers for non-refrigerated equipment with a design maximum temperature of 200 degrees Fahrenheit. It API standard 650 larger diameter tanks requires a minimum thickness of 3/16 inch. Other characteristics of the API 650 storage tank are: it is composed of carbon steel, austenitic duplex stainless steel and aluminum.

In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 API standard 650 larger diameter tanks steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They API standard 650 larger diameter tanks become our regular customer and repeat order to us every month.

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

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
