ISO 630 grade E275 quality D plates API 650 mixed material tanks
The API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API 650 mixed material tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.
No matter what type of storage tank needs to be built, the natural conditions of the geographical area where the tank is located should be fully considered in the design. Because natural conditions will affect the service life, storage safety and construction cost of storage tanks such as API 650 mixed material tanks. Generally, the natural conditions that need to be considered before API 650 mixed material tanks design and construction are: regional temperature, wind load, snow load, ground endurance, external environment corrosion, etc.
In this project, an area of steel storage oil tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2.
As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
If you have any requirements for the mode of transportation of the API 650 mixed material tanks goods, we can also negotiate and meet your requirements. For logistics, first of all, we respect customers' opinions, and then choose the most convenient port and transportation mode with appropriate price for customers.
