Installation on metal pipe (1)
Introduction
The installation method described in this section corresponds to the following combination
of pipe and grounding ring materials. For the installation method corresponding to any other
combination, refer to the table on page 2-13.
Pipe material: Metal
Grounding ring material: SUS material
Required accessories
The following parts are required:

Through-bolts and nuts

Centering guide bushings

Gaskets: We recommend non-rubber gaskets such as those made of joint sheet or PTE.
For recommended internal diameters, refer to Table. 2-2 on page 2-12. Although
rubber gaskets may be used, it is not possible to reduce the fastening torque.
Installation procedure

Install the detector as shown in Fig. 2-11. The torque level for tightening the bolts is not
related to the gasket material. See Table. 2-1 on page 2-8 for the appropriate torque. For
the internal diameter of the gaskets, see Table. 2-2 on page 2-12.

To use rubber gaskets for a low fastening torque, refer to page 2-20.
CAUTION
Please note that the use of rubber gaskets and a lower fastening torque may result in
insufficient surface pressure between the lining and the grounding ring, resulting in leakage.
