Generally, external environment corrosion should be considered before design and construction of atmospheric pressure storage tank and so on storage tanks. The corrosion on the outer surface of storage tank is often worse than that on the inner surface. Especially in the chemical industry area, there are often acid fog, alkali or salt dust in the atmosphere. These impurities form an active corrosive medium with dew or steam and oxygen in the atmosphere. The corrosion of the external environment of the storage tank shortens the maintenance period of the storage tank, even causes the storage tank to be scrapped in advance, which affects the normal operation of the storage and transportation.

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 atmospheric pressure storage tank 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 is an American standard for welding flat bottom vertical storage tanks. This atmospheric pressure storage tank standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as atmospheric pressure storage tank crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site

The results of adopting two-level atmospheric pressure storage tank service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and atmospheric pressure storage tank after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
