Rubber Expansion Joint : Hand-Built Type
To absorb expansion and contraction of the pipeline, Noise and vibration absorption in pipeline, Eccentricity and symmetric of the pipeline absorption, Pipeline life extension.
1. "Filled Arch" construction reduces above movement by 50%.
2. The degree of Angular Movement is based on the maximum extension shown.
3. To calculate approximate movement of Multiple Arch expansion joints, take the movement show in the above table and multiply by the number of arches.
4. Flange Dimensions is ASME/ANSI B16.5 CL. 150#, ASME/ANSI B16.47 CL 150# Ser A. and AWWA C207 CL. D 150#.
5. The constructions of a one set Control Unit is Stud Bolt 1ea, Nut 8ea, Control Rod Plate 2ea and Special Washers 2ea.
6. The flange connection can be transformed by request of customer.(JIS. DIN, ANSI, etc)
