Installation on PVC pipe (2)
Introduction
The installation method described in this section is to be used for the following
combination of pipe and grounding ring materials. For the installation method used for
any other combination, refer to the table on page 2-30.
Pipe material: PVC
Grounding ring material: Non-SUS material
Required parts
The following parts are required:
• Through-bolts and nuts
• Gaskets:
No gaskets are necessary due to the provision of a PTFE gasket.
When using a rubber gasket, two gaskets of the same material and
of two thicknesses, 0.5 to 1.0 mm and 3.0 to 4.0 mm, are required.
See Table 2-3 and 2-4 on page 2-16 for the appropriate
dimensions.
• Protective plate: A protective plate is required if tightening the bolts to the
specified torque may deform or damage the PVC pipe. Use
stainless or hard metal 1 mm thick or more. For the shape of the
metal, see Figure 2-31.
Installation procedure
The installation procedure varies depending on conditions such as the fastening torque
and the need for a protective plate. Choose one of the following three methods as
applicable.
1. Use this method to install the detector to the specified fastening torque.
Install the detector as shown in Figure 2-33. See Table 2-5 on page 2-27 for the
appropriate fastening torque. For dimensions of the rubber gaskets, see Table 2-3
and Table 2-4 on page 2-16
