What Are Casing Spacers?

When it comes to any project in the oil and gas industry, we think about the different pipes required and the machinery that’s needed. But many accessories are essential to building the proper pipeline.

Some of those overlooked components are casing spacers. These are some of the possible casing fillers that can be used.

Types of Casing Fillers

When carrier pipes are required, casings are also used inside. This setup will leave a space in between these two pipes, known as the empty annulus. Within this space, various types of fillers can be used, including:

  • Casing spacers
  • Cement mortar
  • Bentonite
  • Vapor corrosion inhibitors (VCIs)
  • Petroleum Wax
  • Sand

Casing Spacers vs. Annulus Fillers

Casing fillers seem like a small part of installing these types of projects, but they are also an essential part. They are used to center pipes in casings.

Casing Spacers

Casing spacers, also known as casing insulators, provide your pipes with several benefits. Using them in your project will help:

  • Improve a carrier pipe’s performance
  • Improve reliability
  • Increase its lifecycle
  • Ensure accurate alignment
  • Provide support
  • Reduce pipe installation time
Annulus Fillers

Annulus fillers are used in some cases instead of casing spacers. These fillers have their advantages in terms of cost and ease of application. But what happens when repairs need to be made on the pipes?

Casing Spacers - Why Are They Necessary?

Casing spacers can be beneficial when repairs are required. If annulus fillers have been used during a repair, these might escape the pipe throughout the process. So after the repairs, it will need to be replaced once repairs are completed.

When using casing spacers, repairs are not only easier, but they can be done faster. Casing spacers can also be made from different materials like:

  • Wood
  • Stainless steel
  • Carbon steel
  • Polyethylene
  • Epoxy-coated steel
