Finding the Right HDPE Innerduct for Your Telecom Project

We produce high-density polyethylene (HDPE) pipes that offer numerous benefits. Constructed with anti-corrosion materials, these pipes resist moisture and wear, making them durable and reliable. The exterior of the HDPE innerduct is abrasion-resistant, effectively preventing damage from both environmental elements and subterranean movement.

Reach out to us to discuss your needs for hdpe steel strip pipes. Our knowledgeable sales team can help you choose the best options to meet your requirements.

Our engineering expertise in HDPE pipe manufacturing is complemented by our hands-on experience in deploying HDPE across diverse locations and applications. We can fulfill your supply requirements regardless of the project scale—whether you need HDPE for a small extension or require multiple truckloads, we have you covered.

Here is a concise summary of my findings after consulting both PVC - Schedule 80 manufacturers and HDPE conduit suppliers. Here’s what I learned:

PVC Schedule 80 Manufacturer: "We don't know much about HDPE and don't consider it a direct competitor. Our focus is on highlighting how PVC is lightweight, easier, and quicker to install compared to metallic conduit."

HDPE Manufacturer: " HDPE is superior to PVC in many aspects. Many professionals are now updating their standards to include HDPE.

HDPE comes in continuous lengths, reducing the need for couplings and gluing. When coupling is necessary, specialized two-part epoxies or UL-listed HDPE Shurlock couplings can be used. HDPE is flexible enough to navigate around obstacles when placed in a trench. While HDPE does have higher expansion and contraction rates compared to PVC, its underground installation mitigates this issue. HDPE can be installed at temperatures as low as -40°F, whereas PVC becomes very brittle just below freezing. Wall thickness is comparable; Schedule 80 HDPE conduit is even slightly thicker than Schedule 80 PVC. Not all HDPE is UL-listed; only Schedule 40, Schedule 80, and SDR 13.5 HDPE are UL-listed. Ensure to request UL-listed variants specifically."

Since HDPE is solely used underground, its expansion and contraction issues are less problematic. There are significant cost benefits in using HDPE duct, and as it gains acceptance, HDPE is likely to surpass PVC for all underground installations.

When selecting the right HDPE innerduct for your telecom project, several questions often arise, such as:

• What are the durability advantages of HDPE innerduct? HDPE’s resistance to corrosion, chemicals, and abrasion makes it exceedingly durable and long-lasting, reducing maintenance costs.
• How does HDPE perform in extreme temperatures? Unlike PVC, which becomes brittle in cold weather, HDPE maintains its flexibility at extremely low temperatures, making it ideal for diverse climates.
• What installation benefits does HDPE offer over PVC? HDPE’s continuous lengths and fewer joint requirements simplify installation, decrease labor costs, and improve the overall reliability of the conduit system.
• Are there any specific industry standards for HDPE innerduct? Yes, certain grades like Schedule 40, Schedule 80, and SDR 13.5 HDPE are UL-listed, ensuring they meet stringent safety and performance criteria.

By thoroughly considering these factors and common questions, you can make an informed decision when choosing HDPE innerduct for your telecom project.
