ASTM A216 grade WCA external floating roofs API standard 650 flexible liquid storage tanks

API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API standard 650 flexible liquid storage tanks Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum Storage Tanks."

API standard 650 flexible liquid storage tanks, Oil tanks can be divided into above ground storage tanks, underground storage tanks, offshore tanks and submarine tanks according to their installation positions. Oil tanks can be divided into crude oil tanks, fuel oil tanks, lubricating oil tanks, edible oil tanks, etc.. According to the use of oil tanks, oil tanks can be divided into production tanks, storage tanks, etc.. According to the external style, oil tanks can be divided into vertical tanks, horizontal tanks, etc.. According to the composition structure, oil tanks can be divided into fixed roof storage tank, floating roof tank, spherical tank, etc.

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 standard 650 flexible liquid storage tanks is highly desired and the thermal post-heat treatment is impractical.
