API standard 650 liquid-storage tanks hose systems

The API 650 specification provides guidelines for the API standard 650 liquid-storage tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.

Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API standard 650 liquid-storage tanks. The mechanical cleaning of the API standard 650 liquid-storage tanks can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API standard 650 liquid-storage tanks cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.

Thickness as it Affects Preheat and Post-heat Requirements
Plate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the API standard 650 liquid-storage tanks used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.
