Tank RL Diffuser

[RollyC]

I would like to solicit ideas from expert fabricator or designer if the attached diffuser is safe to use in the gasoline storage tank. I'm thinking of static electricity at the perforated portion of diffuser. Thank you.

According to API and NFPA, the initial fill should be constrained to 3 feet per second (1 meter per second) velocity in the piping network ending at the tank to minimize static generation until the fill pipe is submerged by some amount. After that, the diffuser exists to minimize stirring up BS&W and possibly other maintenance related issues. If the inlet stream includes mixed phases (liquid and gas) the diffuser design has to be completely different. If you post the drawing we can comment further.
