1.6 Sectional ring rail
It consists of rolled rings fixed from both sides using M6-screwed catches.
Magnetic bridges are located at both ends with resistive units in between. The
number of segments must be selected according the following table:
The fixing mechanism enables for radial adjustment of 0–58 mm. The sectional
ring rail is designed for pipe diameters of 840–1560 mm (4 units). The required
distance ‘M’ must be read from Table 1.
