single-deck pontoon-type floating roof API Std 650 horizontal tank

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.Low-pressure storage tanks for Liquefied Hydrocarbon Gases
API Std 650 horizontal tank Primary Components: In general, primary components include those components that may be stressed to a significant level, those whose failure would permit leakage of the liquid being stored, those exposed to a refrigerated temperature between –60°F and –270°F, and those that are subject to thermal shock. The primary components shall include, but will not be limited to, the following parts of a single-wall tank or of the inner tank in a double-wall tank: shell plates; bottom plates; roof plates; knuckle plates; compression rings; shell stiffeners; and manways and nozzles including reinforcement, shell anchors, pipe, tubing, forgings, and bolting.The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API Std 650 horizontal tank tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.Enterprise style: unity, pragmatism, responsibility, and endeavorOperation Policy: realistic management, innovative technology, high quality, fast efficiency, low cost and complete service. Enterprise spirit: every year, every day, we should make progressEnterprise development is a process of continuous pursuit of progress. This spirit is reflected in the whole three-dimensional space of every person, every event and every time point in our enterprise. We should always continue to explore, break through and improve.The main reason of "small breathing" loss of API Std 650 horizontal tank is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API Std 650 horizontal tank also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API Std 650 horizontal tank is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
