API 650 mechanically-anchored flat-bottom tanks flanges

Vertical storage tanks Security against Damage
The assemblies of relieving devices shall be secured against damage in service, the effects of storms, or mishandling. Access ladders and platforms that meet API 650 mechanically-anchored flat-bottom tanks plant safety rules are suggested.
Vacuum-relieving Devices
A vacuum-relieving device, when used, shall be as direct in inflow as possible with no pockets where moisture can collect, and it shall have no piping except a weather hood ahead of the inlet. An adequate vacuum-air inlet shall also be provided.

Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API 650 mechanically-anchored flat-bottom tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.

Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API 650 mechanically-anchored flat-bottom tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API 650 mechanically-anchored flat-bottom tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.
