API 5L grade X42 pipe API Std 650 self-anchored flat-bottom steel tanks

The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m. The surrounding backfill with clean sand or fine soil should be no less than 0.3m thick; the API 650 oil tank API Std 650 self-anchored flat-bottom steel tanks operation platform ladder selection unit is considered in a unified manner. The buried operation well is designed for buried horizontal oil tanks, and the two are compatible.

Generally, the building area temperature of the API Std 650 self-anchored flat-bottom steel tanks should be considered before the tank design and construction. The temperature in the API Std 650 self-anchored flat-bottom steel tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API Std 650 self-anchored flat-bottom steel tanks, the higher the corresponding pressure and the more volatile loss.

The thickness of the API Std 650 self-anchored flat-bottom steel tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.
To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in.
(2.5)(0.375) + 0.75 = 1.69 in.

Management information and high efficiency. Because of the rapid flow of API Std 650 self-anchored flat-bottom steel tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
