Products UsedViscotaq Outerwrap PE, Viscowrap HT

    The rehabilitation of the coating systems on two critical gas pipelines in northern Mexico addressed essential needs for durability, safety, and corrosion protection within the region’s natural gas infrastructure. Located approximately 80 miles outside Monterrey, Nuevo León, the 42″ Gas Pipeline, known as “Los Ramones,” and the 36″ Gas Pipeline, connecting “Estación 19” to “Los Ramones,” underwent extensive coating restoration from September 2023 to September 2024. This initiative was crucial in maintaining the long-term operational integrity of both pipelines, given their roles in transporting natural gas across Mexico.

    The rehabilitation work involved the application of advanced coating solutions designed to withstand Mexico’s demanding environmental conditions. The coating system used included Viscowrap HT (12″ x 33′) with an outer layer of Viscotaq Outerwrap PE (6″ x 100′), a configuration selected for its robust corrosion protection capabilities. The unique visco-elastic properties of Viscowrap HT allow it to bond immediately to substrates without primer, offering exceptional resilience against corrosion. Additionally, its self-healing nature makes it resistant to harsh soil conditions, ensuring the pipelines are better protected against potential damage and corrosion in the future. The result is a durable, low-maintenance solution that reduces operational costs while enhancing pipeline safety and longevity.

    Throughout the year-long project period, a total of 8,891 feet (2,710 meters) of the 36″ gas pipeline was coated, covering approximately 83,829 square feet (7,788 square meters), while 23,687 feet (7,220 meters) of the 42″ gas pipeline received coating over a surface area of approximately 260,600 square feet (24,211 square meters). This extensive application provides long-term protection against degradation, preserving the pipelines’ structural integrity and reducing the need for future maintenance.

    The successful completion of this project was made possible through a strong partnership between CENAGAS, the owner of the pipelines, and G.A. Energy Services, the contractor tasked with executing the rehabilitation work. This collaboration highlights the importance of proactive maintenance in critical infrastructure projects, especially within Mexico’s natural gas supply network, where reliability and safety are paramount. By extending the operational life of these pipelines, the project supports Mexico’s energy infrastructure and ensures a stable and safe gas supply for the future.
