Fitting the flange with pipe

Important information on installing the flanges with tube

The axes of the flanges with tube must be aligned carefully to each other during 
assembly. The angle deviation must be under 1°. Plan suitable reinforcements or 
support constructions on thin-walled steel ducts.

On easily accessible measuring distances up to 2 m, the flanges with tube can be 
aligned using a suitable auxiliary tube (for standard flange diameter 70 mm). 

Fig. 2: Auxiliary tube to align the flanges on measuring distances under 2 m 

Use an optical adjustment device on longer or not easily accessible measuring distances.
