Notes:
1, RS Flexible Sleeve Expansion joint can produce deflection which can be up to 5.85°.
2, The number in the table are ones under the condition that there is no deflection.
3, The expansion joints are sealed by rubber rings and they can't withstand the axial tension themselves. Generally, they are installed on the Straight Pipeline. If they are installed near bent pipes or T-tubes, buttresses are needed to prevent them from leaking.
4,Single-plate Short Pipes can be substituted by casting iron straight pipes.
5, Flange connection: GB2555-81
