API 650 ground supported flat-bottom tanks striking plates

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 650 ground supported flat-bottom 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.

API 650 internal floating roof tanks are generally called internal floating roof tanks, floating roof tanks, internal floating disk storage tanks, internal floating disk tanks, etc., specifically referring to API 650 storage tanks and oil tanks with aluminum, stainless steel, etc. The API 650 ground supported flat-bottom tanks inner floating roof of series material is an environmentally friendly and economical storage tank that prevents liquid from volatilizing.

The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous API 650 ground supported flat-bottom tanks pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.

When the day light gradually decreases, the temperature of oil in the API 650 ground supported flat-bottom tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API 650 ground supported flat-bottom tanks will also decrease. When the pressure in the API 650 ground supported flat-bottom tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API 650 ground supported flat-bottom tanks through the open vacuum valve, which is the "suction" process of the oil tank.
