Efficient Ductile Iron Pipe Installation: Harnessing the
Power of Horizontal: Directional Drilling's 'Cartridge Method.'

Why is Ductile iron pipe the ideal companion for trenchless technology?

  • Unmatched and Time-Tested Strength: Ductile iron pipe delivers standard pressure capabilities of up to 350 psi, effortlessly handling pull-back and heavy loadings. Its material strength ensures long-term structural integrity, minimizing maintenance and replacement costs.
  • Optimal Thrust Distribution for Enhanced Performance: Unlike other pipe options, Ductile iron pipe features optimal thrust distribution. Forces are evenly spread around the bell and barrel, reducing stress concentration points and maximizing durability and longevity.
  • Flexibility Redefined: Trenchless installation requires flexibility, and Ductile iron pipe delivers just that. It offers superior pulling forces, granting contractors greater flexibility during installation, enabling them to navigate challenging terrains, accommodate alignment variations, and overcome obstacles effortlessly.
  • Convenient "Cartridge" Options: Limited easements and tight spaces pose unique challenges during installation. However, Ductile iron pipe offers convenient "cartridge" options, designed specifically for these situations. These cartridges make handling and maneuvering the pipe easier, ensuring hassle-free installation in even the most restricted areas.
  • Efficient Installation and Peace of Mind: Ductile iron pipe offers effortless joint assembly, saving time and effort on the job site. Its quick and easy system boosts efficiency and productivity. Additionally, it can be easily located from the surface, providing peace of mind and easy access for monitoring and maintenance.
  • Consistent Performance, Seamless Integration: Ductile iron pipe delivers unwavering performance regardless of temperature variations. It remains reliable in elevated temperatures and during pull duration. Moreover, its seamless integration eliminates recoil and pipe movement caused by thermal expansion, enabling direct connection to existing infrastructure and saving valuable time, resources, and costs.
  • Ensuring Safe and Sustainable Water Delivery: By opting for HDD and utilizing 90 percent recycled Ductile iron pipe, you are securing a safe and sustainable water delivery system for future generations. This modern approach surpasses outdated installation methods and eliminates the risks associated with subpar pipe materials, prioritizing the long-term safety and reliability of your water infrastructure.

Embrace the power of trenchless technology and Ductile iron pipe today to build a better tomorrow, where water and wastewater systems meet the needs of the present and the challenges of the future with unmatched efficiency and performance.
