1. All expansion joints are finshed with retaining flanges,limit
rod units are available on special request.
2. Pressures shows are recommended“operating”,test pressure is
1.5time“operating”,burst pressure is 3 time “operating”.
3. Vacuum rating is based on neutral installed length without
external load.Products shall not be installed “elongated”on vacuum
applications.
4. Do not weld near the expansion joints or weld the steel flanges
to the piping after the expansion joints are installed .This will
either burn or seriously damage the expansion joints.
