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.
