There must be a 90-degree elbow.
As required, ones with radii of 1R, 1.5R, 2R and even larger are available; the most common ones in the market are those with a 1R radius. The elbow of PVC/FRP depends not on FRP, but on PVC. As for elbows, there are 90-degree and 45-degree ones; you can choose whichever you prefer.
There are 90°C elbows, with bending radii that can be 1 time the diameter or 1.5 times the diameter; however, for PVC/FRPP elbows, a radius of 1.5 times the diameter is more commonly used
