Doha, the bustling capital of Qatar, has transitioned into a global hub for infrastructure, logistics, and heavy industrial operations. Driven by the ambitious goals of the Qatar National Vision 2030, the region is witnessing unprecedented scale in civil engineering projects, port expansions, and oil and gas developments. From the massive Hamad Port operations to the expansion of the Doha Metro and extensive commercial developments in Lusail City, the reliance on high-performance machinery is absolute. At the heart of this machinery lies the critical circulatory system: hydraulic hose assemblies.
Operating in the Arabian Gulf presents unique challenges for hydraulic systems. The local environment is characterized by extreme ambient temperatures that routinely exceed 50°C during summer, high relative humidity, airborne dust, and highly saline coastal winds. Standard hydraulic components degrade rapidly under these conditions, leading to premature failure, fluid leaks, and costly operational downtime. Consequently, there is an escalating demand in the Doha market for premium-grade, temperature-resistant, and abrasion-proof hydraulic hose assemblies that can withstand severe pressure fluctuations while remaining cost-effective.
The combination of high pressure and external environmental stress requires hydraulic hoses built with advanced metallurgy and rubber compounding. In Doha's construction and marine sectors, hoses must not only contain the internal working pressures of hydraulic fluids but also resist external abrasion from sand, UV radiation from intense sunlight, and chemical exposure from oils and saline water. As a leading exporter, Shaanxi Kelong provides customized hydraulic hose assemblies that integrate multi-layer steel wire reinforcement with specialized outer covers to offer maximum durability and flexibility under these harsh local conditions.
Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, which grew from Xianyang Kelong Rubber Products Institute.
It Is a Technological innovation company integrating R&D, production and sales, concentrates on hydraulic seal set, high-pressure hose, coal mine auxiliary transportation equipment, repairing coal mine auxiliary transportation equipment, technological service and etc. The products has been widely applied to Coal mining industry, Civil Aviation, High speed railway, Engineering machinery, Wind power and etc. The high-quality products and services are trusted by customers all over the world.

The industrial landscape in the Middle East, particularly in Qatar, is shifting towards higher efficiency, strict environmental regulations, and zero-tolerance policies for workplace hazards. Hydraulic systems are the primary muscle behind earthmoving, heavy transport, and manufacturing sectors. Modern engineering operations in Doha now demand smart, reliable, and sustainable hydraulic hose assemblies. As a leading exporter, we stay aligned with these global trends by introducing state-of-the-art products that combine high durability with cost-effective pricing models.
Doha's skyline is a testament to massive infrastructure investments. Tower cranes, hydraulic excavators, pile drivers, and concrete pumps are continuously operating in high-heat environments. In these applications, hydraulic hoses (such as the SAE 100R2 and EN 853 2SN) are subjected to extreme pressure spikes and continuous flexing. Our wire-reinforced rubber hoses are designed to prevent catastrophic failures, ensuring that construction projects proceed without interruption.
Qatar is a global leader in liquefied natural gas (LNG) production. Offshore drilling rigs, extraction facilities, and refinery operations require hydraulic systems that can handle aggressive media under massive pressures. The U/Y Type Polyurethane Sealing Rings and custom wire braid hydraulic hoses we export are engineered to resist chemical corrosion and extreme heat, making them ideal for the oil and gas infrastructure in Mesaieed and Ras Laffan Industrial Cities.
With the expansion of Hamad Port, marine cargo handling and dredging activities have surged. The salty marine air and direct contact with seawater accelerate chemical corrosion. Our hydraulic guide rings and custom-sheathed hydraulic hose assemblies are designed to resist saltwater intrusion, preventing leaks that could lead to environmental contamination and operational delays.











Boasting over 500 employees, nearly 180 of whom are engineers and technicians, along with an R&D center and 7%+ annual R&D investment, we ensure robust and diverse production capacity.

With ISO and IRIS certifications, our professional team conducts strict checks throughout the production process, guaranteeing top-notch product quality.
When sourcing hydraulic hose assemblies for the Doha market, balancing cost and performance is crucial. "Cheap" does not mean compromising on quality; instead, it refers to optimizing production efficiency, sourcing high-grade raw materials directly, and leveraging advanced manufacturing technologies to reduce overall unit costs. Shaanxi Kelong achieved this balance by integrating R&D, manufacturing, and direct export logistics, eliminating middlemen markups and passing the savings directly to Qatari industrial buyers.
