Pros and Cons: High Density Polyethylene Pipe vs Ductile Iron Pipes

Texas directional boring contractorHave you started a construction project, but can’t trench around your site? Directional drilling services are your best bet to get the job done. When you begin looking for a Texas directional boring contractor, there are a lot of factors that need to be taken into consideration before you undertake your project. Trenchless boring, or horizontal directional drilling, is a low impact method of installing underground piping.

So what kinds of pipes do you use? Your directional boring contractors can help you make a final decision, of course. But if you’re looking for more information before breaking ground, there are two popular options to know about: High Density Polyethylene Pipes versus Ductile Iron Pipes.

Ductile Iron Pipes

Most modern pipe installations use ductile iron piping; however, this kind of pipe is traditionally used for trenching. It’s less common in the directional boring industry. Ductile iron pipes are beneficial when used in certain soil types and ground conditions. These pipes are particularly useful in areas of high pressure, where the surface pressure can transfer to the pipe and cause damage or deformations in the pipe materials. Despite its traditional use in trenching, ductile iron pipes can be fitted with connectors that improve the overall flexibility of the system and allow it to be used in directional boring.

High Density Polyethylene Pipes

This high-grade plastic piping is the standard for directional boring operations. According to a 2017 survey, high-density polyethylene pipes are used approximately 49.7% of the time. This material is flexible and pliable, making it ideal for a variety of conditions. Compared to ductile iron piping, HDPE pipes don’t require a separate fitting during installation because of their welded joints. In some cases, where more structural integrity is needed, high density polyethylene pipes are used as liners within other piping materials.

Once you’ve selected your Texas directional boring contractor, they will have an idea of what kind of pipes would work best for your project. However, knowing what you are putting in and why is important considering how integral underground piping is to the infrastructure of American society. The type of pipe you need depends a lot on the kind of job you are looking to complete. Your contractor may have more choices than just ductile iron pipes and high density polyethylene pipes, but those are some of the most common materials used.
