API standard 650 liquid storage tanks external pressure

The API 650 oil tank stiffener ring and backing strip, if used, are primary components, and they shall comply with the requirements of R.2.1. The API standard 650 liquid storage tanks stiffener ring may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange. One rat hole with a minimum radius of 3/4 in. shall be provided at each longitudinal shell joint and ring juncture weld.Application scope of API 650 petroleum storage tank:
1. API standard 650 liquid storage tanks Working pressure: atmospheric storage tank;
2 API 650 petroleum storage tank working temperature: -30℃～150℃;
3 API 650 petroleum storage tank liquid medium: various oil products, including naphtha, gasoline, diesel, kerosene, crude oil, fuel oil, heavy oil, benzene, xylene, methanol, ethanol;
4 API 650 petroleum storage tank volume: current design considerations generally do not exceed 10,000 cubic metersThe Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks They have very strict requirement for raw materials quality For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on,API standard 650 liquid storage tanks. Drain hole: The drain hole is generally installed at the bottom of the oil tank, used to remove sludge when cleaning the oil tank, and usually used to drain the sewage in the tank. API standard 650 liquid storage tanks Safety valve: The role of the safety valve is to play a safety role when the breathing valve fails during the operation of the oil tank. Its working pressure is slightly higher than the pressure of the breathing valve, which can prevent the tank from being damaged due to the high positive or negative pressure in the tank. The safety valve is usually installed in the middle of the API standard 650 liquid storage tanks top.After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
