Casing Pipe Spacer

Although casing spacers play a small part in the installation process of a water or sewer carrier pipe, the part they play is an important one. 

Also known as casing insulators, they’re able to improve a carrier pipe’s performance, reliability, and life-cycle. In addition, insulators ensure accurate alignment, provide support, and reduce pipe installation time.

Why You Should Use Plastolin Casing Spacers

When you need to install a carrier pipe and casing, you’ll need a medium to fit between the empty annulus (the ring-shaped space between the carrier pipe and casing). For this, you’ll have two options, annulus filler or casing spacers. Unlike annulus filler, casing spacers can provide a number of benefits.


Main filler is sand that is used to fill the empty space between a carrier pipe and its casing. While annulus filler provides insulation, it can make performing repairs on the casing or pipe difficult. For example, if a repair needs to be made, sand will either escape or will need to be removed to reach the carrier pipe. Once the repair is done, the missing sand will need to be replaced.

With Plastolin casing Pipe spacers, there’s no need for filler as metallic spacers will keep the pipe centered and secured in its casing. This means that repairs can be done more efficiently

Variety Of Materials

Plastolin Casing Pipe Spacer can be made with a wide variety of materials. This can include  stainless steel, carbon steel, polyethylene, epoxy-coated steel, and more. The material used is typically polyethylene or Rubber.


One of the biggest benefits that come with using Plastolin casing Pipe spacers is the opportunity to lower installation and maintenance costs. Annulus filler is not only expensive, but it requires extremely intensive labor and can act as an electrolyte, inviting unwanted current to the pipe. Plastolin casing Pipe spacers, however, eliminate the need for annulus filler. This results in efficient installation, repair, and replacement.

Pipe Integrity

When Plastolin casing Pipe spacers are installed on a carrier pipe, they provide protection to the pipe in a number of ways including:

  • Uniform support for the weight of the pipe
  • Electrical Insulation
  • Corrosion Protection
  • Keeping the carrier pipe and casing separate
