Pipe – dimensions, weights, fixing distances
�����
Pipe supports, pipeline elements or, for example, fittings, must be fixed depending on the building situation, the operating conditions and the environmental influences.
The distance of the pipe clamps depends on the diameter of the pipe and the wall thicknesses of the cable conduit, the density of the flow medium and the operating temperature.
The fixing distances indicated are only guide values and should be assessed for every single static application.
