Suhigo's Crawler Pipelayer cluster has been launched to assist in the construction of the Saudi oil project
Today, fifteen 90-ton Crawler Pipelayers emblazoned with distinctive logos stood in formation at SUHIGO's manufacturing base, commencing their voyage to Saudi Arabia. This fleet of heavy-duty equipment, engineered for exceptional efficiency and extreme heat resistance, will serve as core construction assets for Saudi Arabia's major oil pipeline project, braving the harshest challenges of the Middle Eastern desert environment.
Precision Collaboration, Overcoming Delivery Challenges
Confronting dual pressures of tight deadlines and intensive production demands, SUHIGO's team activated "extreme acceleration" mode. The project unit functioned as a high-efficiency "central command system," rapidly coordinating critical components and resources globally to ensure seamless supply chain operations and sufficient production reserves. Technical specialists worked side-by-side with manufacturing teams, eliminating issues instantaneously upon detection. This tightly integrated collaboration enabled the batch production and on-time delivery of fifteen tailor-made Crawler Pipelayers, shattering conventional manufacturing timelines while maintaining rigorous quality standards.
Defying the Scorching Heat, Unleashing Desert Capabilities
Crawler Pipelayers form the "steel backbone" of long-distance oil and gas pipeline construction, undertaking critical tasks including pipe laying, precision alignment, and trenching—where robust load-bearing mobility is indispensable. SUHIGO's 90-ton fleet is purpose-built to conquer extreme Middle Eastern heat: reinforced high-temperature-resistant designs and specialized thermal insulation materials protect power systems and critical hydraulic components. This ensures unwavering performance stability even under Saudi Arabia’s summer conditions exceeding 50°C, amidst blistering sands and relentless sun. These "high-temperature warriors," forged for desert operations, maintain efficient lifting and powerful mobility where conventional equipment falters or fails, delivering "all-weather, all-terrain" operational assurance for project advancement.
Committed to Excellence, Powering Energy Infrastructure

In the harshest desert heartlands, they will forge the vital conduits of progress.
Saudi Arabia's MGS project accelerates progress, with multiple indicators setting new records
On April 23rd, the first joint construction task of the main pipeline of the 6th and 7th sections of the largest-diameter oil and gas pipeline project - the MGS Phase III Pipeline Project in Saudi Arabia, undertaken by the company's affiliated Petroleum Engineering Construction company, was successfully completed, marking the official start of the pipeline joint and backfilling work for this project.
Facing difficulties such as heavy production and operation tasks and relatively scarce resources, the Saudi MGS project department of the company, on the one hand, vigorously promotes advanced equipment and technologies such as vacuum pipe hanging machines and welding laser video surveillance, and on the other hand, implements an integrated management model and flexibly adjusts the construction arrangements during Ramadan, laying a solid foundation for the efficient advancement of the project.
With the conclusion of the Eid al-Fitr holiday for Saudi Muslims, the project team entered an "accelerated mode", taking the welding of the main line as the core, closely coordinating the upstream and downstream processes, conducting tracking non-destructive testing, strictly controlling the welding quality, implementing quota assessment and fulfilling it the following month, effectively stimulating the enthusiasm of employees for work.
During the critical period of the project's breakthrough, the project team actively coordinated materials, ensured sufficient reserves of construction resources, and closely cooperated with the technical studio to promptly solve on-site problems. After seven days of arduous efforts, the first automatic welding unit completed 160 welds, with a one-time welding qualification rate of 100%, setting a new historical record for the company's overseas large-diameter long-distance oil and gas pipeline projects. It quickly sparked a competitive craze of "learning from each other, catching up, helping each other and surpassing".
In the scorching desert atmosphere, the entire project line closely cooperated, achieving seamless connection in pipe laying, assembly, welding and other links. The daily construction of a single unit for trench excavation and pipe laying exceeded 600 meters. The automatic welding units No. 2 and No. 3 were not lagging behind, respectively achieving 24 and 20 welds in a single day, pressing the "accelerator" for the project construction with practical actions.
Next, the project department will adhere to the principle of "safety first and quality priority", continuously strengthen safety and compliance management, enhance the coordinated advancement of each process, accelerate the formation of large-scale assembly line operations, and promote the high-quality operation of the project.
