I can only think of Walter Sobchek right now. “You’re in over your head Mani”.

What class? Have you read the applicable section of their rules?
What system does the pipe belong to? Ballast fill / suction line that ends in tank? Or another system passing through the tank?

By NAB. Are you trying to say NiAlBr?
