API Std 650 duplex stainless steel tanks shells

API 650 sets minimum requirements for the design, material, construction, and testing for aboveground, open and closed-top, cylindrical API Std 650 duplex stainless steel tanks steel storage tanks in different capacities and sizes, roughly equating to the pressure of the atmosphere (not greater than the weight of the roof plates).

Preheat Treatment
Many laboratory tests have shown preheat treatment of carbon steel to 300°F-400°F to be the equivalent of the post-heat treatment at no less than 1100°F insofar as the physical properties of the weldment are concerned.40,41 Some tests have indicated a slight advantage of the post-heat treatment. Most of the tests have been made on plates 3/4 in. - 1 in. thick; results must be viewed with caution if preheating is applied appreciably beyond this thickness range. However, for all practical purposes, improvement resulting from preheating is sufficiently well established so that preheat should be considered for field fabrication of API 620 crude oil tank plates over 3/4-in. thick whenever toughness of the tank API Std 650 duplex stainless steel tanks is highly desired and the thermal post-heat treatment is impractical.

The construction period comparison of mechanical cleaning and manual cleaning for vertical storage tank, API Std 650 duplex stainless steel tanks. The API Std 650 duplex stainless steel tanks mechanical cleaning period is short, and the construction period is not affected by the size of the storage tank and the amount of sludge in the tank, and the cleaning equipment operates 24 hours a day. The manual cleaning of the API Std 650 duplex stainless steel tanks has a long construction period, which is easily affected by the external environment, and the number of workers is limited by the size of the storage tank and the amount of sludge.
