Pipe Clip Spacing

Pipe clip spacing for plastic pipe


The distance between pipe clips or any pipe supports is dependant on the size of pipe, wall thickness, material of pipe and the temperature of the fluid / gas flowing through it.

  • Size of the plastic pipe used: The larger the diameter, and greater the wall thickness, the wider the spacing between your supports / clips. This is because the pipe becomes more rigid.
  • Material: PVC and ABS have roughly the same support centres, "softer" materials such as polyethylene will require more frequent support.
  • Temperature: It is the nature of plastic that it "softens" and becomes more ductile at higher temperatures, so the higher the temperature,the more frequent the support centres need to be to prevent it from flexing and in worst case scenario, sagging. A sagging pipe can have dire consequences; it can lead to a build up of settled solids and restrict flow or even block the pipe, it can also encourage air locks to form, especially in low pressure / head pipe systems - thirdly - it looks awful!
