Standard angles: 15°, 30°, 45°, 60°, 75° and 90°. Tolerance for ≤ DN 200 is ±2,0°, for > DN 200 is ±1,0°.
Standard arm lengths L1, L2 +/- 50 mm
Entering the buildings
For entering buildings vertical elbows 90°, with standard arms 1,5 m and 1 m (for diameters range of DN 20 to DN 150) are used. When designing or ordering it is necessary to specify, that elbow is used for entering the building. The reason for it is: different placement of alarm wires.
If requested we can make special angles, arms or add service valves.
