Premium wire-braided and spiral hoses engineered for extreme mechanical stability, flexible radius operations, and robust pressure management under intensive industrial environments.
The Verona region in Veneto, Northeast Italy, stands as a critical intersection of specialized manufacturing, extensive viticulture machinery engineering, and world-renowned marble quarrying (principally in Valpolicella and Sant’Ambrogio). These sectors subject machinery to extreme environments defined by massive mechanical loads, high atmospheric dust concentration, and severe cyclic vibrations.
Within this ecosystem, the demand for High Pressure Hydraulic Steel and Rubber Hoses is defined by strict operational safety margins. Equipment deployed in marble cutting, stone block handling, and vineyard automation requires continuous hydraulic supply circuits capable of handling up to 80 MPa of working pressure without degradation or leakage. Standard industrial components frequently fail under these conditions; our specialized hoses, engineered to EN853, EN856, and SAE100 parameters, ensure zero-downtime operation.
Our ultra-high pressure spiral hoses (such as the EN 856 4SH and SAE100 R12) are designed to withstand abrasive stone slurry and continuous dynamic pressure surges encountered during large-scale marble extraction.
Compact, highly flexible textile rubber hoses (SAE 100 R6) provide tight bending radii and weather-resistant outers for advanced grape harvesting and pruning systems.
Founded in 1996, evolving from the Xianyang Kelong Rubber Products Institute, Shaanxi Kelong New Materials Technology Co., Ltd. has established itself as an innovative powerhouse in hydraulic sealing systems, high-pressure rubber hose design, and specialized industrial engineering.
With an annual R&D investment exceeding 7% of total revenue and an expert workforce of over 500 personnel—including nearly 180 engineers and technologists—we combine advanced polymer science with state-of-the-art manufacturing hardware. Our processes leverage Austrian DMH sealing lines alongside high-performance extrusion machinery imported from Italy, ensuring our products easily meet European standards.
High-integrity polyurethane and elastomer seal units tailored for hydraulic cylinders working in high-friction, contamination-heavy, and high-temperature environments.
Our engineering solutions deployed across tough global environments, ensuring reliable heavy machinery operation, mining support, and wind turbine stability.
Ultra-tough, high-pressure hydraulic hose for rock-solid machinery performance in mining and stone excavation projects across the Verona foothills.
Rigorously tested under dynamic lifting loads, our multi-spiral hose ensures stable pressure distribution in complex logistics hubs like Quadrante Europa.
Innovative engineering combining high salt-water corrosion resistance with premium flexibility. Ideal for marine and heavy transport infrastructure.
Upgrading the hydraulic pitch control loops of regional clean-energy networks with premium multi-million cycle rated pressure lines.
Sealing tight and lasting long under extremely abrasive tunnel excavating pressures, significantly lowering maintenance intervals.
Need bespoke hoses, custom fittings, or sealing kits designed to exact Italian industrial specifications?
Get Custom QuoteKelong New Materials achieves industry-leading quality limits through strategic capital investments in manufacturing assets. Our sealing elements are processed on premium machinery imported from DMH Company in Austria, which sets the gold standard for high-accuracy polymer sealing shapes.
Simultaneously, our high-pressure rubber hose manufacturing lines are imported from Italy, ensuring precise control over reinforcement tension, elastomer wall thickness consistency, and computerized vulcanization controls. This combination of European hardware and dedicated engineering is unique, translating to superior service life in Italian field applications.
Our entire hydraulic catalog operates under ISO 9001 and IRIS certifications, guaranteeing traceable supply chains, zero-defect processing, and adherence to international mining and machinery safety norms.
Premium hydraulic cylinder rings, wiper assemblies, and customized compound seals designed to fit international standards and niche excavation equipment.
As Verona's heavy machinery OEMs move towards carbon-neutral operations and clean digital monitoring, hydraulic components must adapt. Standard elastomers degrade rapidly when exposed to modern biodegradable synthetic hydraulic fluids (HEES/HEPR). Shaanxi Kelong is pioneering the transition with advanced materials formulation research:
Shaanxi Kelong New Materials commands a significant 8% market share in the domestic Chinese coal-mining machinery seal market, consistently ranking among the top three providers nationwide. Through extensive investments in Italian-imported extrusion technology and Austrian-licensed CNC seal cutting centers, we are scaling our presence globally.
For our distributors and heavy industrial clients in Verona, Italy, this massive production footprint provides an unbeatable combination of cost competitiveness, rigorous quality compliance, and rapid OEM adaptation capability.
Expert answers regarding standard compliance, operational tolerances, material performance, and logistics support for Italian business buyers.
