More potential power in pipeline construction.
HDD technology has shortcomings over long distances.
Horizontal drilling rigs for underground pipeline construction (HDD: Horizontal Directional Drilling) are a rapid, cost-effective and environmentally friendly means of laying supply lines for oil and gas below obstacles and beyond. However, physical factors, i.e. the diameter of the pipe, the thrust of the drilling rigs (HDD rigs) and local geological features limit the length that can be tunnelled.
Pipe Thruster - more pull and push for existing HDD rigs.
New auxiliary equipment from Herrenknecht can help supply existing HDD rigs with more pulling and pushing power. The Herrenknecht Pipe Thruster - installed at the destination hole - supports the HDD rig at the start shaft when the pipeline is to be withdrawn. This means that the forces exerted on the pipeline are distributed better because the Pipe Thruster (PT) has an additional 500 tonnes of pushing power and can shift the pipeline towards the starting point at a speed of 5 meters per minute. The PT is suitable for current pipeline types measuring between 20 and 48 inches.
Advantage of the Pipe Thruster.
- Increases the range of use for HDD rigs
- 500 tonnes of additional pushing and pulling power
- Variable clamping ring - support for current pipeline diameters between 20 and 48 inches.
- Remote-controlled synchronization of HDD rig and Pipe Thruster
- Speeds of up to 5 meters per minute
- Quick to pack and prepare for transportation to the next work site
Areas of Application
- Crossings beneath rivers and straits
- Sea outfall
- As a rescue tool for trapped pipelines
