There’s a small component; the flow diagram labels it as a check valve, but the technician said it’s an expansion joint

As shown in the figure, the steam pressure is below 120 degrees. A check valve is different; is it necessary to add an arrow for the expansion joint as well? The direction of the arrow should be opposite to the direction in which the steam flows. The pipeline leads from the steam generator to the steam network

I’ve never seen check valves installed on steam pipes; the flange sizes for check valves are quite short
Your master is right; don’t doubt it
