ISO 630 grade E275 quality B plates API standard 650 self-anchored tank

Pipeline transportation of API 650 oil tank is not less than the maximum consumption of 3 to 5 days. The daily operating time of API standard 650 self-anchored tank office buildings and fuel oil equipment is 12-16 hours; for high-end residential hotel buildings, the daily operating time is 16-24 hours.

To scientifically evaluate the remaining service life of the API standard 650 self-anchored tank, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API standard 650 self-anchored tank, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 self-anchored tank are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

All API standard 650 self-anchored tank fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

Steel transportation because of the special material of API standard 650 self-anchored tank steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
