API 650 mechanically-anchored flat-bottom tanks seismic use group i

Inspection of weld and micro crack of API 650 mechanically-anchored flat-bottom tanks: the inner and outer surface of API 650 mechanically-anchored flat-bottom tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API 650 mechanically-anchored flat-bottom tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at API 650 mechanically-anchored flat-bottom tanks design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.For open top and fixed roof API 650 tanks, the net working capacity is the liquid volume contained between the minimum operating level (top of API 650 tanks API 650 mechanically-anchored flat-bottom tanks outlet connection) and the maximum operating level [limited to the bottom of overflow connection, 75 mm below foam chamber connection, or 150 mm below rim, whichever is greater.Enterprise Motto:Integrity, harmony, dedication, innovation and developmentAbility is the cornerstone of success; action is the ladder of successGrow with the enterprise; progress with the enterpriseGive a platform to those who actually do things and a stage to those who successfully do thingsDare to be the first, to pursue excellence.our company is leading supplier of API 5CT casing pipes in China.
