P&C Duct Type DB-120 Heavy Wall - 20'

The Prime Conduit Nonmetallic P&C Duct Type DB is expertly engineered from Prime Conduit’s exclusive high modulus PVC compound, specifically developed to meet the rigorous demands of power and communications applications. This duct is designed for use in both direct burial and concrete-encased installations, making it an ideal choice for a variety of environments. With a temperature rating of 90°C, Type DB ensures safe and efficient operation, even in challenging conditions.

Key Features:

• Superior Material Composition: The high modulus PVC compound used in the manufacture of Type DB provides exceptional strength and flexibility, allowing the duct to maintain its structural integrity under pressure. This unique formulation is tailored for demanding environments, ensuring that the conduit can withstand the rigors of outdoor conditions without compromising performance.
• Trenching Guidelines: For optimal installation results, it is essential that trenches are graded true and kept free from stones and soft spots. This ensures that the conduit is securely positioned and reduces the risk of damage during backfilling. Backfill material should also be free from stones and firmly tamped around the sides of the conduit to develop maximum supporting strength. It is important to note that tamping on top of the conduit is not recommended, as it may induce undue stress and compromise the duct's integrity.
• Backfill Recommendations: In situations involving rocky soil where achieving an even trench bottom is challenging, a selected backfill should be used prior to laying the conduit. This backfill should extend at least 6 inches above the top of the conduit and should not be tamped to avoid excessive pressure. Once the final backfill is in place, tamping can be utilized to finish the grade to your specifications, ensuring a stable and supportive environment for the conduit.
• Layered Installation Techniques: The method of direct burial may vary based on soil conditions, load requirements, and engineering preferences. A widely accepted practice involves laying one tier of ducts at a time, followed by backfilling, and repeating the process until the desired spacing of ducts is achieved. This approach simplifies the installation process and allows for adjustments based on specific project needs.
• Heavy Wall Option: For applications requiring additional durability, the Type DB-120 Heavy Wall Utility variant is available. Meeting the stringent DB-120/ASTM F-512 standards, this heavy wall duct features a minimum wall thickness that correlates with a 400,000 modulus. This added strength makes it an excellent choice for installations subjected to significant external pressures, providing peace of mind for professionals working on demanding projects.
