Before pipeline installation begins, the construction area must be cleared and prepared.
Engineers and surveyors mark the proposed pipeline route to ensure proper alignment and compliance with environmental regulations.
Heavy machinery, such as bulldozers and excavators, remove trees, vegetation, and obstacles along the right-of-way (ROW). The land is then graded to ensure a stable working surface.
Environmental protection measures, including silt fencing, matting, and water diversion techniques, are implemented to minimize soil erosion.
Once the ROW is prepared, trenches are excavated to lay the HDPE pipe.
Trenches are dug to the required depth to protect the pipeline from external forces and meet regulatory guidelines.
Horizontal Directional Drilling (HDD) is used to install HDPE pipes under roads, rivers, or environmentally sensitive areas, reducing surface disruption.
After trenching, HDPE pipes are transported to the site and staged along the ROW for fusion.
HDPE pipes are laid out along the trench in preparation for fusion.
Pipes are inspected for defects, and surfaces are cleaned to ensure strong fusion joints.
Fusion welding is a critical step in HDPE pipeline construction, creating seamless, leak-free joints.
For tie-ins, connections, and repairs, electrofusion couplings are used to join HDPE pipes securely.
During installation or repairs, flow must be controlled safely.
Our exclusive high-capacity squeeze tools allow for controlled shutoff of HDPE pipes up to [maximum diameter]”, a capability no other company offers.
Unlike traditional methods, our squeeze tools prevent damage to the pipe while allowing for precise shutoff and maintenance.
Once fusion is complete, the pipeline is lowered into the trench and secured.
A layer of sand or fine soil is placed under the pipe to provide support and prevent abrasion.
HDPE pipe is carefully placed into the trench using side booms or excavators.
The trench is filled with select materials to protect the pipe from external forces. Native soil or controlled backfill material is used as required.
Before commissioning, the pipeline undergoes rigorous testing to ensure integrity.
The pipeline is filled with water and pressurized to detect leaks or weaknesses.
In some cases, compressed air is used to test pressure retention and structural integrity.
Certified inspectors verify all fusion joints and ensure compliance with project specifications.
Once testing is complete, the ROW is restored to its original condition.
The land is regraded to match pre-construction contours and prevent erosion.
Native grasses and vegetation are replanted to stabilize the soil and restore ecological balance.
Silt fences, water bars, and other erosion control measures are installed and monitored.
With construction and restoration complete, the pipeline is ready for operation.
Documentation is completed to confirm pipeline placement and compliance with design specifications.
The pipeline is pressurized and connected to the system for operation.
Regular inspections ensure long-term pipeline integrity and performance.
