2.5.5: Installation on a metal pipe using non-SUS 

grounding ring material

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

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

any other combination of materials, refer to Table 2-8 on page 2-32.
PTFE gaskets are provided for this type of installation. If you supply the gaskets, 

Azbil Corporation recommends non-rubber gaskets such as joint sheet or PTFE.

To install a flanged detector on a metal pipe using non-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 2-6 on page 2-26 for the appropriate torque.
See Table 2-7 on page 2-31 for the inner diameter of the gasket.

Lining

Grounding ring

PTFE gasket
