Steam Line Piping Project – Tongonan Geothermal Power Plant, The Philippines
The Challenge
A local construction engineering company in the Philippines was entrusted to lead the project of conducting steam line piping at the Tongonan Geothermal Power Plant. However, issues arise as pipe welding is a rather complex process, and the terrain proved challenging for manoeuvring and transportation of machines. In addition to working under unbearable conditions of the hot steam, long hours of constant exposure to the sun can drain out welding operators’ stamina and concentrations – which severely affects productivity.
To not disrupt project progression, it is of utmost importance for the company to work with an established equipment supplier that can present high-quality solutions. For that reason, Hasting Motor Corporation, Denyo’s authorised dealer in the Philippines, was approached to supply the welding machine that best suits the described application.
The Denyo Solution
After accessing the situation of the customer, Hasting Motor Corporation confidently recommended the Denyo DAW-500S engine-driven welder as the perfect tool for work of such nature. First of all, it has top-class onsite manoeuvrability due to its compact (126 × 80 × 87 cm) and lightweight body (435 kg) compared to other conventional welders in the market. As such, transporting multiple Denyo DAW-500S can be cost-efficient as it mitigates the need for multiple trips, for a smaller transportation truck can now carry more equipment and materials per trip.
In terms of performance, the Denyo DAW-500S is capable of a 75% duty cycle (percentage of time that a machine will safely operate) and delivers stable arc performance in any situation. With the equipped Thyristor-based control and high-performance permanent magnet generator, lesser heat will be generated during loaded operation to ensure on-site reliability and long-term durability.
Results
The steam line piping project has concluded successfully, and the customer was highly pleased with the welding results and dependability of Denyo’s product. Each Denyo DAW-500S welding machine ran for 6 hours per day and had zero disruption throughout the entire operation. The Denyo DAW-500S is truly an engine-driven welding machine with heavy-duty performance that can rise to any challenges.
