API Std 650 ambient temperature tanks structural shapes
API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 ambient temperature tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
Proper use of API Std 650 ambient temperature tanks and precautions:1. The API Std 650 ambient temperature tanks must be used within the safe height range;2. Check before use to ensure that the safety valve and breathing valve are flexible and easy to use;3. The explosion-proof and fire-proof safety measures for oil tanks are implemented effectively;4. The oil level in the API Std 650 ambient temperature tanks should be accurately measured when receiving and delivering oil, so as to prevent overflow or empty;5. In the process of receiving and sending oil, the flow rate of oil should be controlled, and it should not be too fast to avoid electrostatic accidents.
In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API Std 650 ambient temperature tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.
Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
The company has huge steel API Std 650 ambient temperature tanks products stock all the year round to meet the urgent needs of customers. For stock products, we can arrange delivery within 3 days. The transportation department and shipping department shall coordinate and follow up to update the progress to customers regularly, i.e. where the goods have arrived, so as to let customers not worry and rest assured. Think about what the customers think and what the customers are anxious about, solve problems for customers efficiently and effectively, is the direction of our unremitting efforts.
