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 620 crude oil storage tank design 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.

Welded steel API 620 crude oil storage tank design storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 620 crude oil storage tank design all adopt on-site production and installation of storage tanks.

API 620 crude oil storage tank design Nondestructive testing is a technical means to detect the weld defects of large vertical tank and judge whether the weld is qualified by using the characteristics of sound, light, magnetism and electricity without damaging the tested object. Common nondestructive testing methods: ultrasonic testing (UT), magnetic particle testing (MT), liquid penetrant testing (PT) and X-ray testing (RT).
