2.4.7: Installation on a metal pipe using SUS grounding 

ring material

The installation method described in this section is for installation on a metal pipe 

using SUS grounding ring material. For the installation method corresponding to any 

other combination of materials, refer to Table 2-5 on page 2-12.
For installation using SUS grounding ring material, Azbil Corporation recommends 

non-rubber gaskets such as joint sheet or PTFE. Although rubber gaskets can be used, 

it is not possible to reduce the fastening torque. See page 2-17 for installation using 

rubber gaskets.

 CAUTION

The use of rubber gaskets is not recommended and can cause leakage.

To install a wafer detector on a metal pipe using SUS grounding ring material 

and a specified torque:

•  Install the detector as shown in the following illustration. The torque level for 

tightening the bolts is not related to the gasket material.
See Table 2-1 on page 2-7 for the appropriate torque.
See Table 2-2 on page 2-10 for the inner diameter of the gasket.
