Internal Pipe corrosion

[monirri]

We are doing maintenance to a 50000bls tank in Meta, Colombia. There is some pipe in the plant´s yard, that we could use. Incidentally, I came across a document on the web mentioning the maximun corrosion rate for pipe according to ASME, but didn´t mention the code. Which code adresses this? Thanks

Corrosion allowance is based on design, which means knowing the service conditions that can cause corrosion. There is no code or standard that provides or assumes a corrosion rate, this is specified by the designer. The Code acknowledges what to do with corrosion rates.

Use API-570.
