API Std 650 horizontal tank designed without anchorage

API 650 external floating roof storage tanks are generally called external floating roof API Std 650 horizontal tank tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API Std 650 horizontal tank storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.

API Std 650 horizontal tank, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API Std 650 horizontal tank is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API Std 650 horizontal tank is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API Std 650 horizontal tank?

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API Std 650 horizontal tank base materials, nickel alloy based materials, aluminum base materials, and weld deposited for the nonferrous (aluminum) materials.
