API standard 650 ground-supported liquid storage tanks gauge float wells

For employees' development,  the company's transformation and development provides employees with a broad career development platform. The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate. They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities.Design of Reinforcement for Single Openings in Tank Walls
The 20 in. x 29 in. obround manhole shown in Figure F-5 is located in solid plate in the sidewall of a cylindrical storage tank 45 ft in diameter in an area where the thickness of the wall plate, tw, is 1/2 in. No corrosion allowance is required. The total internal pressure, Pl + Pg, at the horizontal centerline of the opening is 27.5 lbf/in.2 gauge. The thickness of the wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.485 in. The manhole neck is fabricated by welding from 3/8 in. plate. The materials in the API 620 tank wall, the manhole neck, and the reinforcing pad conform to ASTM A516 Grade 60. The joints in the welded steel storage oil tank wall and the longitudinal joint or joints in the manhole neck are double-welded butt joints, spot radiographed in accordance with 7.16 and 7.17.There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API standard 650 ground-supported liquid storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API standard 650 ground-supported liquid storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.As we know, the vertical metal tank, API standard 650 ground-supported liquid storage tanks is welded by many components, and the welding quality of each component determines the later use effect of the API standard 650 ground-supported liquid storage tanks. Professional API standard 650 ground-supported liquid storage tanks manufacturers should have a set of professional skills in the welding process of API standard 650 ground-supported liquid storage tanks. Key points for weld inspection of vertical metal tank, API standard 650 ground-supported liquid storage tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.
