Pipeline protection is essential to ensure durability and prevent costly damages. Both Geotextile Pipeline Weights (GPW) and Incomat Pipeline Cover (IPC) offer different benefits in terms of UV inhibitors and high impact resistance. This section will explore the advantages of each option in these areas.
UV Inhibitors in Geotextile Pipeline Weights
Geotextile Pipeline Weights are designed using high-grade, woven non-coated geotextiles, which are resistant to the harmful effects of ultraviolet (UV) radiation. Prolonged exposure to UV can weaken the fabrics, making them more susceptible to damage and failure. The UV inhibitors in GPW help protect pipelines by minimizing the deterioration caused by UV exposure.

The IPC also provides protection against UV exposure, although the fabric is considered a “lost formwork” until the concrete has cured within. The high-density polyethylene (PE) and polyamide (PA) material used in IPC inherently offers UV resistance. While not as specifically focused on UV protection as GPW, IPC still provides a reliable defense against the damaging effects of UV radiation on pipelines.
Comparing UV Inhibitors in GPW and IPC
Both GPW and IPC provide UV protection for pipelines, with GPW having a more prominent focus on UV inhibitors. IPC is comprised of a UV resistant material but may not be as specialized in UV protection as GPW as its main function is to provide a formwork for the concrete. Ultimately, the choice between the two will depend on the specific requirements of the pipeline project and the level of UV exposure expected.
High Impact Resistance in Geotextile Pipeline Weights
Geotextile Pipeline Weights offer a certain degree of impact resistance due to their construction from woven geotextiles and aggregate fill material. While GPW can provide some protection against impact damage, it may not be as robust as IPC in this regard.
High Impact Resistance in Incomat Pipeline Cover
IPC excels in providing high impact resistance for pipelines. The concrete fill material used in IPC ensures that the pipeline remains protected from potential impact damage during installation, maintenance, or in environments where impact hazards may be present.
Comparing High Impact Resistance in GPW and IPC
When comparing the impact resistance offered by GPW and IPC, IPC has a clear advantage. The fill material provides superior impact resistance, making IPC better suited for environments where pipelines may be exposed to potential impact hazards. In contrast, GPW offers some level of impact resistance, but it is not as strong as IPC. The choice between the two will depend on the specific fill material, the needs of the pipeline project and the expected exposure to impact hazards.
The process of preparing and installing pipeline protection systems is crucial to the success of any pipeline project. In this section, we will compare the steps involved in preparing and installing Geotextile Pipeline Weights (GPW) and Incomat Pipeline Cover (IPC) along the right of way.
Preparing and Installing Geotextile Pipeline Weights
Geotextile Pipeline Weights can be prepared along the right of way, making them an efficient choice for pipeline projects. The following steps are involved in the installation of GPW:
- Excavation: A trench is dug to accommodate the pipeline and the geotextile weights.
- Filling Geotextile: The geotextile material is filled with local aggregate, sand, or gravel and laid along the bottom of the trench, with the pipeline placed on top either filled by hand or using a filling frame.
- Weight Placement: The pipeline weights are positioned over the pipeline, ensuring proper coverage and protection.
- Backfilling: The trench is backfilled with the appropriate material, covering the pipeline and weights to secure them in place.
Preparing and Installing Incomat Pipeline Cover
The Incomat Pipeline Cover, which can also be prepared along the right of way, offers an even higher level of protection than GPW, while maintaining similar efficiency. The installation process for IPC includes:
- Excavation: A trench is dug to the desired depth, considering the diameter of the pipeline and the IPC.
- Filling IPC: The IPC is zipped around the pipeline and filled with highly fluid concrete through the flexible fill inlets.
- Pipeline Placement: The pipeline can either be placed into the trench prior to filling the IPC formwork and filled in place, or after the concrete has cured within the fabric formwork. The Incomat Pipeline Cover is capable of being filled in-situ during water crossings or marsh crossings.
- Backfilling: The trench is then backfilled with the appropriate material, covering the pipeline and IPC.
Comparing the Preparation and Installation of GPW and IPC
Both GPW and IPC can be prepared along the right of way, offering efficient installation processes. The key differences between the two methods include the placement of the pipeline in relation to the protective material and the method of securing the protection in place. GPW requires the use of on-site filling frames or by hand prior to placement on the pipeline. IPC, on the other hand, is wrapped around the pipeline prior to filling, providing options to fill the pipeline protection in place or prior to placing it in the trench.
The choice between GPW and IPC will depend on the specific needs of the pipeline project, as well as factors such as environmental conditions, accessibility, and project timeline.
