Technology Tuesdays: Pre-insulated Pipe

Hello Partners!

Currently, there are investor-owned utilities that offer considerable incentives for installing pipe insulation due to the great potential for energy savings. However, these incentives are for insulation that is installed after-the-fact where insulation was not previously existing. What if the pipe and the insulation can be installed together as a singular measure?

The exciting news is it can!

Relatively new technology called pre-insulated pipe is a ready-to-install product that already has insulation built in. This product is made up of two sets of piping. The internal pipe, called the carrier pipe or cast pipe carries the hot or cold liquid. The second set of piping is called the GRP jacket or casing pipe; this is the outer layer. The spaces between the carrier pipe and the jacket pipe are filled with a polyurethane foam. This foam serves as the primary barrier preventing thermal transfer.

Pre-insulated pipe can be installed anywhere regular process pipe is installed because it is very flexible as well as durable and is most commonly used in district heating and cooling, oil and gas, infrastructure and utility, food processing, pharmaceutical, chemical, water treatment, and winery applications. Other benefits of pre-insulated pipe are that it can be used to transport a large variety of liquids, it is light weight, has a long service life, and above all, it is cost effective. Pre-insulated pipes are a steadily growing market and are projected to grow from $6.39 billion, which was the market share in 2019 to $10.21 billion by 2024.

Please do not underestimate the amount of energy savings that can be achieved by the simple act of insulating your pipes or installing pre-insulated pipes. Depending on the application, your pipes can account for a tremendous amount of heat loss which translates to energy loss.

The savings never stop!
