Positioning of branches
When positioning branches, e.g. house connection pipes on the main pipe, attention must be paid to the special features
of the plastic casing pipe system. Even short connecting pipes with small dimensions are 'clamped in' by the surround-
ing ground, so their movement is impeded. Again, the natural fixed point is formed in the length of the connection pipe,
so restoring forces act on the main pipe. The different movements and force ratios of the main pipes and the connection
pipe must therefore be considered in every case.
