382 PRESSURE & DESIGN DATA Pipe Support
All piping systems require that the support system accommodate the weight of the pipe, joint connections, fluid and other system compo- nents. In addition, consideration may be necessary in reducing stresses, accommodating thermal expansion or contraction, building settle- ment, seismic movement, etc. The following tables provide guidelines for grooved steel piping products without concentrated loads between
supports.
Flexible Joints
For pipe runs when linear movement is accommodated by the flexible coupling:
Nominal Size ANSI Inches DN
1-1/4 - 2
32 - 50
2-1/2 - 4
65 - 100
5 - 24
125 - 600

For pipe when linear movement is not required: Distance Between Supports

Note:
• The requirements of ANSI, ASME or other code groups may require additional supports.
• Refer to Technical Data Sheets G810, G820, and G830 for more information.
