API Std 650 welded aluminum storage tanks thermal stress relief

Prefabricating API Std 650 welded aluminum storage tanks components before construction can improve construction efficiency, save time and cost, and is currently a common method for the construction of large vertical storage tanks. The main prefabricated components of a large vertical API Std 650 welded aluminum storage tanks include the tank body, the storage tank wall, the top of the storage tank, the bottom of the storage tank, and the accessories of the storage tank. The prefabrication of the components should follow a reasonable workflow, and carry out appropriate heat treatment and testing, so as to improve manufacturing accuracy.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 welded aluminum storage tanks is highly desired and the thermal post-heat treatment is impractical.Corrosion allowance, if specified, shall be added to calculated API 650 tanks shell and self-supporting roof thicknesses; to minimum nominal thicknesses of bottom and supported API Std 650 welded aluminum storage tanks roof plates; to nozzles and manholes; and to all exposed surfaces of internal structural members and non-removable internals.Aspire to technological innovation and pursue first-class quality steel API Std 650 welded aluminum storage tanks products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.If you are in the search of best quality of API Std 650 welded aluminum storage tanks structural steel plate then you have landed on the right place.
