API 650 special tank manufacturer's standard drain

API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 special tank tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 special tank storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.

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 650 special tank 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.

The main types of metal storage tanks are vertical dome roof tank, vertical external floating roof tank, vertical inner floating roof tank, spherical oil tank and horizontal oil storage tank. API 650 special tank is vertical tank. The capacity of vertical dome roof oil storage tank is generally less than 10000 cubic meters. The wall plate adopts sleeve type fillet weld, and it is usually installed by inverted or forward installation method during construction.

Insist on the spirit of development and indomitable entrepreneurship; the spirit of leading science and technology and striving for first-class affairs; the spirit of strict management and market development; the spirit of taking the lead in setting an example and selfless dedication; and the spirit of people-oriented and enterprise ownership.

In the process of API 650 special tank steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API 650 special tank different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
