Fig. 2000: Heavy Duty Pipe Saddles
ORDERING: Specify figure number, pipe size and description.
NOTE:
1. Tolerances: R=1%-0
Other Dimension – 1/16, Except Plate Thickness – 1/32 Angle – 1 1/4 Deg.
2. Full Encirclement Saddle Plates shall be used on all cross country pipelines, on Grade X-46 or higher strength pipe, and on all station pipework designed to operate at or in excess of 90% of min. specified yield strength. Segmental Saddle Plates shall be used on station pipe work designed to operate at less than 50% of min. yield strength.
3. For maximum spans of pipelines using saddles use Standard Engineering Practice.
4. Pipe Support of sleeper under the saddle shall be designed to accommodate full axial movement of the pipeline and saddle.
5. Vent hole 1/4 to be drilled in each segment of saddle.
