API Std 650 aboveground welded storage tanks welding operator

Generally, external environment corrosion should be considered before design and construction of API Std 650 aboveground welded storage tanks 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 impact tests for API 620 welded storage tanks used pipe (including structural members made of pipe), bolting, and forgings, shall be in accordance with ASTM specifications ASTM A333 (seamless only) pipe, ASTM A36 Mod 1 plate, ASTM A131 Grades CS, D, and E steel plate, ASTM A633 Grade A CSA G40.21 Grades 38WT, 44WT and 50WT high-strength low-alloy structural steel plate, ASTM A350 carbon and low alloy steel forgings, and ASTM A320 Grade L7 bolts.API 650 is an American standard for welding flat bottom vertical storage tanks. This API Std 650 aboveground welded storage tanks 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 API Std 650 aboveground welded storage tanks 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.Based on the principle of “sincerity and win-win cooperation”, our company keeps forging ahead.
