In modern urban infrastructure construction, trenchless technology is essential for protecting surface environments and reducing costs. Recently, YG Machinery delivered an advanced pipeline installation solution—a heavy-duty HDD rig—to a municipal contractor in Vancouver, Canada.
The project required laying a 450-meter high-pressure natural gas pipeline without disrupting local ecosystems or surface structures. Here is how our custom directional drilling equipment solved complex underground conditions while meeting North American standards.
📌 Project Snapshot
- Location: Vancouver, British Columbia, Canada
- Project Type: Urban High-Pressure Natural Gas Pipeline Upgrade
- Pipeline Specification: Φ315 mm HDPE (SDR 11), Total Length: 450 meters
- Geological Conditions: Wet clay, unthawed seasonal frost, and abrasive quartz sandstone (UCS ~50 MPa)
- Equipment Deployed: YG-320 Heavy-Duty Horizontal Directional Drilling Rig
- Key Challenge: Zero-surface-disruption restriction near residential heritage trees & dense underground utility grid

Canadian Municipal Grid Upgrade Introduces High-Performance HDD Rig
The Canadian client faced extremely strict environmental regulations when upgrading the pipeline network in a core residential area of Vancouver. The surface was filled with century-old trees, and the underground space was crowded with dense utility cables. Traditional open-cut trenching was completely impossible. The client urgently needed a powerful, precise, and stable machine to complete a seamless underground crossing.
After researching online and comparing multiple global brands, they chose our specialised trenchless product series. Through several rounds of technical video meetings, our engineers carefully analysed the soil profile of the project site. To handle the complex ground conditions, mixing backfill soil and hard sandstone, the client finally decided to import this heavy-duty HDD rig. It provides high pulling force and massive torque, which perfectly match the local requirements for large-diameter back-reaming and long-distance pilot hole drilling.
Choice Factors of a Horizontal Directional Drilling Rig for High-Density Urban Areas
After confirming the cooperation, matching the exact equipment model became the key to project success. Because the construction site sat right next to a busy residential area, the workspace was tight. Furthermore, local authorities imposed strict rules on noise control and exhaust emissions.
To ensure the machine passed local Canadian equipment inspections smoothly, our engineering team upgraded this custom horizontal directional drilling rig across multiple specifications.
- Power System Configuration: It features a high-power, low-emission engine that provides stable power output even in cold weather.
- Hydraulic Push-Pull Design: It uses a high-efficiency motor or cylinder system to maintain a consistent pullback force during continuous, long-distance reaming.
- Compact Body Dimensions: The overall transport width is tightly controlled, allowing easy transport and quick anchoring on narrow neighbourhood roads.
- Cold-Weather Hydraulics: Upgraded antifreeze hydraulic fluid lines and pre-heating system to handle temperatures down to -15°C.
- North American Compliance: Standardized threaded joints (API thread compatibility) allowing direct pairing with North American drill rods and sonar transmitters.
- EPA/CARB Engine Option: Equipped with Tier 4 Final / Stage V compliant diesel engines to meet Canadian municipal emission limits.

Conquering Frozen Soil and Rock: Directional Drilling Equipment Performance
During pilot hole drilling at a depth of 4.2 meters, the crew encountered a sudden stratum shift into highly abrasive quartz sandstone (unconfined compressive strength reaching 50 MPa), causing drill head torque to spike abruptly.
To prevent pipe locking or drill rod breakage, YG’s after-sales technical support initiated an immediate video conference with the Vancouver field crew:
- Reaming Strategy: Applied a 3-stage expanding process (Φ300mm ➔ Φ500mm ➔ Φ750mm) using custom PDC rock reamers to guarantee hole stability before final pullback.
- Mud Formula Optimization: Increased bentonite density and added high-molecular polymers, raising mud flow to 320 L/min at 80 bar to cool the bit and sweep out heavy rock cuttings.
- Torque Management: Leveraged the YG-320’s 12,000 N·m powerhead torque at a steady 60 RPM, maintaining a controlled penetration rate of 0.8 m/min through the rock layer.
High Efficiency and ROI: Why This HDD Machine for Sale Wins the Market
After finishing the hardest part of the pilot hole, the project moved to continuous three-stage reaming and final pipe pullback. As the reaming diameter reached the target 750 mm, the high-load continuous working capacity of the machine proved its value.
In North America, contractors demand high efficiency. The reason this specific HDD machine for sale is so popular in the international market is not just its top-tier performance parameters, but also its great user convenience and economic benefits.
- Automated Control System: The cabin offers a wide view and humanised control joysticks. Operators can monitor push-pull force and powerhead speed in real time.
- Efficient Pullback Performance: Relying on up to 320 kN of maximum pullback force, it finished the final large-diameter pipe pullback in just 8 hours, keeping the axis deviation far below Canadian standards.

Real-World Results from Directional Drilling Equipment Performance
The Vancouver gas pipeline upgrade project finished exactly 4 days ahead of schedule. According to the official feedback data from the client, the equipment operated with zero failures throughout the construction period, and the average drilling speed increased by 25%.
By using trenchless technology, the contractor completely avoided expensive surface restoration and road reconstruction costs, directly saving over 150,000 Canadian dollars. At the same time, residents praised the low noise levels and zero traffic disruption, which helped the client build an excellent reputation for green construction with the local government.
💬 What the Client Said: “We were initially concerned about shipping a Chinese HDD rig to Canada due to strict North American emissions and hydraulic stability requirements in freezing temperatures. However, YG custom-installed cold-start aid systems and CSA-compliant electrical components for us. The YG-320 performed flawlessly through 450 meters of rocky ground, helping us hand over the project 4 days ahead of schedule.”
