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.
