Maximum Recommended Support Spacing

Support spacing and stiffness for vibratory service

Applications:

  • This table provides the maximum sleeper spacing for straight runs of steel pipe for a double-acting reciprocating compressor operating at the specified speed
  • The lateral mechanical natural frequency for the specified sleeper spacing is also calculated

Instructions:

  • Enter the operating speed of the compressor
  • Press the "SLEEPER SPACING" button

Cautions/Tips:

  • Additional supports will be required near elbows, flange sets, valves, etc.
  • Note that support spacing is based on the assumption that supports are rigid; since elevated pipe supports generally are not rigid, the support spacing must be reduced for installations using elevated supports.
  • These guidelines are most applicable in the immediate compressor area
