API Std 650 floating-roof tanks fittings

API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 floating-roof tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.

The cost of mechanical cleaning for vertical storage tank, API Std 650 floating-roof tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API Std 650 floating-roof tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API Std 650 floating-roof tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.

All API Std 650 floating-roof tanks fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.
