2.5.6: Installation on a PVC pipe using SUS grounding
ring material
The installation methods described in this section are for installation on a PVC pipe
using 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.
Although rubber gaskets can be used, they are not recommended. See page 2-38 for
installation using rubber gaskets.
CAUTION
The use of rubber gaskets and a lower fastening torque is not recommended and
can cause insucient surface pressure between the lining and the grounding ring,
resulting in leakage.
If tightening the bolts at the specied torque threatens to warp or damage the PVC
pipes, you will need to use a protective plate. See page 2-37 for installation of the
protective plate.
