Optional design procedures of API standard 650 stainless and carbon steel tank
Welded steel API standard 650 stainless and carbon steel tank storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 stainless and carbon steel tank all adopt on-site production and installation of storage tanks.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API standard 650 stainless and carbon steel tank where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
The water dissolved in the oil will be separated out from the oil stored in the API standard 650 stainless and carbon steel tank for a long time, and the acidic water layer will appear at the bottom of the API standard 650 stainless and carbon steel tank for a long time, which will accelerate the corrosion of the API standard 650 stainless and carbon steel tank and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 stainless and carbon steel tank must be inspected and cleaned regularly to check the hidden danger.
Enterprise Motto:Integrity, harmony, dedication, innovation and developmentAbility is the cornerstone of success; action is the ladder of successGrow with the enterprise; progress with the enterpriseGive a platform to those who actually do things and a stage to those who successfully do thingsDare to be the first, to pursue excellence.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API standard 650 stainless and carbon steel tank steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API standard 650 stainless and carbon steel tank steel transportation industry.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
