In large-scale infrastructure projects like oil & gas pipelines and municipal networks, large diameter HDD rigs have become essential equipment for long-distance, big-diameter pipeline installation. These machines can easily handle trenchless installation of pipes exceeding φ1000mm, significantly reducing environmental disruption. Today, we highlight Hengwang Group's HWF460—a high-performance large diameter HDDrig engineered for challenging projects.

Why Choose Large Diameter HDD Rigs?

Compared to conventional equipment, large diameter HDDrigs offer three unmatched advantages:

(1) Superior Crossing Capacity: Achieves continuous drilling up to 1500m, easily traversing rivers, highways, and complex terrains

(2) Oversized Pipe Support: Handles pipe pullback up to φ1200mm, meeting main oil & gas pipeline requirements

(3) Smart Operation System: Real-time monitoring with automatic trajectory correction

The Hengwang HWF460exemplifies these capabilities as an exceptional large diameter HDD rig, with its massive 460-ton pullback force conquering the toughest engineering challenges.
