Horizontal Directional Drilling
- Guided pilot hole is drilled along a bore path under the obstruction, or per the required alignment
- Drilling fluids are used in the bore hole to stabilize and lubricate the operation
- Various reamers may be used to enlarge the pilot hole
- Multiple passes may be required to accommodate the required pipe OD
- Drilled bore hole is typically enlarged to 1.5 x OD of new pipe
- Joined pipe is pulled back after bore hole preparation is completed
- Drilled holes are stable for a limited time. Entire fused lengths are typically pulled in at one time, with no interruptions
- Smaller Bore Hole: Fusible PVC® will require a smaller bore hole diameter than other pipe systems. A smaller bore-hole diameter means that there will be less back reaming, less drilling mud, and less spoil disposal.
- Safe Pulling Allowance: Fusible PVC® has a safe pulling allowance that is significantly greater than that of most other pipe systems. This facilitates longer or more difficult installations with Fusible PVC®.
- Lower Material Weight: Fusible PVC® will have a lower overall material weight than other pipe systems. This means that drilling equipment size and cost may be lower, and pull-in lengths may be longer when installing Fusible PVC®.
- Standard Fittings: Fusible PVC® utilizes standard mechanical joint fittings. No special fittings or equipment are required for connections. As a result, Fusible PVC® is easy to connect to and maintain.
- Immediate Reconnections: Fusible PVC® may be reconnected to a system immediately after installation, with no "material relaxation time" required.
