API 650 welded steel storage tanks method for estimating tank uplift

For the welding of API 650 welded steel storage tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API 650 welded steel storage tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.

API 650 welded steel storage tanks Liquid Relief ValvesA tank, which is likely to operate completely filled with liquid, shall be equipped with one or more liquid relief valves at the top of the roof, unless otherwise protected against overpressure. When such valves are, in effect, supplementary relief devices, they may be set at a pressure not greater than 1.25 times the design pressure. Because the relief valve at the pump, which provides the inflow of liquid to the tank, is set at a pressure greater than 1.25 times the design pressure of any tank that may be built under these rules, provision should be made for preventing overfilling of the tank by a self-closing float valve, by some practicable pilot-valve control, or by any other proven device.

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API 650 welded steel storage tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

Continue to refine and improve the company's common core values.Corporate values are the evaluation criteria for the production and operation behavior, products, services provided, social reputation and credit of enterprises, the biggest API 650 welded steel storage tanks goal pursued by enterprises and the criteria for judging things accordingly, and the core of corporate culture. Companies in the extraction of common value note: simplicity; Unity of coordination; API 650 welded steel storage tanks Systemic; Respect for talents; Focus on giving back to society; Try to make a factual argument in order to gain wider acceptance.
