If they've got $45 million revenue for 2020 (at the maximum end) from the existing pipeline, that leaves $285 million through to 2022. Assuming production capacity of 40 kt per annum ($120 million revenue) after the second line is installed, they'll struggle to get there without a new facility or a third line at Changxing.

They'll probably be able to stockpile some material in 2020 but relying on 100% output doesn't sound like good business to me. I think we'll hear about a new factory sometime next year.
