Simulation problems of composite pipeline materials

The project uses composite pipes; due to considerations related to temperature and pipe diameter, the pipe material chosen is a composite of Q235 + 316 (12+4). A corrosion allowance of 1 mm is applied, with 316 serving as the coating layer and Q235 as the base material. I would like to ask the experts: how can such materials be simulated? In my opinion, it should be modeled according to Q235 with a thickness of 16 mm, of which 4 mm is allocated as corrosion allowance. Such a result should be on the conservative side.

Conservative; simulated separately; opinions are for reference only

I don’t know why this material was chosen; the expansion coefficients of stainless steel and carbon steel differ greatly, so it’s certainly not suitable for high temperatures

For pipes in what industries aren’t there any design specifications?
