High-performance hydraulic and pneumatic seals optimized for heavy industrial applications.
The global rubber seal market is transitioning from basic NBR (Nitrile) compounds to high-performance FKM, FFKM, and HNBR materials. As industries move toward "Industry 4.0," the demand for seals that can withstand extreme pressures (>700 bar) and temperatures (-50°C to +250°C) has surged. Global procurement strategies now prioritize manufacturers with integrated R&D capabilities and digitized quality control.
The industrial landscape in North Korea, particularly in the Chollima Steel Complex and various mining sectors in South Hamgyong, requires rugged, high-durability sealing components. As the country focuses on modernizing its railway infrastructure and coal extraction machinery, the need for "Zero-Leakage" hydraulic systems is critical. Localized applications focus on resilience against abrasive dust and variable climate conditions.
Located in the heart of China's industrial corridor, Shaanxi Kelong provides a logistical and technological bridge. We offer Information Gain by utilizing Austrian DMH and Italian manufacturing technologies to produce seals that outperform standard imports. Our efficiency allows for a 30% reduction in lead times while maintaining ISO/IRIS-certified quality standards.
Tailored sealing solutions for the specific challenges of the DPRK's industrial environment.
North Korea’s vast anthracite reserves require heavy-duty hydraulic supports. Our KL09 Rod Seals are engineered to withstand the rigorous reciprocating motion of mining cylinders, preventing fluid loss even in slurry-rich environments. The use of reinforced PTFE ensures high wear resistance, extending machinery uptime in mines like those in Anju.
Pyongyang’s metro and the national railway network rely on pneumatic systems that must operate reliably in extreme winter temperatures. Our KL80 Pneumatic Seals utilize TPE/NBR blends that remain flexible at -40°C, ensuring safe braking and door operations across the northern provinces.
With a heavy reliance on hydroelectric power (e.g., Supung Dam), the seals used in turbine governors must be resistant to water-glycol fluids and high-velocity friction. Our custom FKM O-rings provide the thermal stability required for long-term underwater service.
Shaanxi Kelong New Materials Technology Co., Ltd., founded in 1996, is a technological pioneer in hydraulic sealing and high-pressure fluid systems.
Our sealing products adopt the equipment and production technology of DMH Company in Austria, known for precision CNC seal machining. For fluid transfer, our hydraulic hose production base utilizes a complete set of equipment imported from Italy. We are ranked in the top three of the domestic coal machine sealing industry, capturing an 8% market share through relentless innovation.
Supply of ultra-tough hydraulic hoses for mining machinery in the Musan Iron Mine, enhancing durability under high-impact conditions.
Implementing high-pressure stability hoses in mobile cranes for skyscraper projects in Pyongyang’s Mirae Scientists Street.
Custom seals for wind turbine gearboxes in coastal renewable energy projects, providing salt-spray and ozone resistance.
Integration of sensors within large-diameter seals to monitor wear and pressure in real-time, reducing catastrophic failures in critical North Korean infrastructure.
Global shift toward sustainable rubber compounds that maintain performance while reducing the carbon footprint of industrial manufacturing.
Seals specifically designed for vibrations exceeding 300km/h, a technology Kelong has already mastered for high-speed rail networks.
