API 650 mechanically-anchored flat-bottom tanks documentation requirements

storage tanks API 650 mechanically-anchored flat-bottom tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.

Design of Compression-ring Regions
In this project, a cylindrical tank 30 ft in diameter is designed for an internal pressure of 5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade A steel for thicknesses of 1/2 in. and less. The top course of the butt- welded cylindrical sidewall is 1/4 in. thick, including a 1/16 in. corrosion allowance. The tank API 650 mechanically-anchored flat-bottom tanks roof is a butt-welded spherical dome with an internal radius of 30 ft and a thickness of 1/4 in., including a 1/16 in. corrosion allowance. The maximum design liquid level is 6 in. below the plane of the juncture of the roof and sidewall.

Our company will accept the product quality objection registration record, pass it to the API 650 mechanically-anchored flat-bottom tanks production unit and relevant departments, and timely coordinate the supervision of product API 650 mechanically-anchored flat-bottom tanks quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
