API Spec 5L pipe API Std 650 welded tanks for oil storage

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API Std 650 welded tanks for oil storage tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.

Prefabrication requirements of large vertical API Std 650 welded tanks for oil storage accessories: the prefabrication shall be deepened as far as possible in strict accordance with the requirements of construction drawings and specifications, according to the principle of convenient installation and construction, as much as possible to reduce the installation workload, especially the workload of high-altitude operation. The prefabricated accessories shall be strictly inspected to ensure the quality and make marks. In addition, effective measures should be taken to prevent deformation, damage and corrosion during storage, transportation and stacking on site.

Thickness as it Affects Preheat and Post-heat Requirements
Plate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the API Std 650 welded tanks for oil storage used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.

BEBON is a large steel group with finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. We are committed to creating a various culture system with its own characteristics, and work hard to create a first-class steel plate company in China. Based on the business philosophy of quality-oriented and strengthened management, the company continues to develop in this industry.

Steel transportation because of the special material of API Std 650 welded tanks for oil storage 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.
