Direct manufacturer-grade fluid transfer components compliance tested with ISO 1436, SAE J517, and EN 853/856 international hydraulic benchmarks.
The demand for ultra-high-pressure hydraulic systems in the Grenville market has undergone a structural transformation. Fueled by expanding civil infrastructure, heavy mining logistics, forestry processing, and modern agricultural automation, regional engineering firms require reliable, high-impulse hydraulic hose assemblies that minimize operational downtime.
Globally, the hydraulic steel wire braided and spiral rubber hose market is moving toward high-flexibility, anti-abrasive synthetic polymers capable of enduring continuous working pressures exceeding 420 bar (6,000 PSI). In sub-zero northern temperatures and harsh coastal-adjacent corrosive atmospheres common to regional operations around Grenville, standard off-the-shelf hoses suffer premature thermal degradation and cover abrasion.
As a premier global manufacturing exporter, Shaanxi Kelong New Materials Technology Co., Ltd. bridge this gap by delivering advanced fluid conveyance systems tailored for Grenville’s demanding operational loads, combining Austrian precision sealing technology with state-of-the-art Italian hose production equipment.
Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, growing from the Xianyang Kelong Rubber Products Institute into a global powerhouse for advanced fluid transmission and sealing systems.
We are a technological innovation enterprise integrating R&D, continuous vulcanization production, and global commercialization. We specialize in high-pressure hydraulic hose assemblies, engineered hydraulic seal sets, coal mine auxiliary transportation equipment, and specialized repair services. Our product solutions are vital to coal mining, civil aviation, high-speed rail networks, heavy engineering machinery, renewable wind power, and maritime rigs worldwide.
Kelong ranks among the top three leaders in domestic mine hydraulic sealing and fluid power industries. With continuous 7%+ annual revenue invested into R&D, complete sets of production equipment imported from Italy, and seal manufacturing technology licensed from Austria’s DMH Company, we guarantee unmatched stability for Grenville importers and distributors.
Understanding the structural differences between wire-braided and high-tensile wire-spiral steel reinforce layers is key to selecting the correct hose for long cycle life in Grenville’s heavy industries.

Wire-braided hydraulic hoses (such as SAE 100 R1, R2, or EN 853 1SN) feature high-tensile steel wire crisscrossed in a basket-weave structure. This offers superior flexibility and smaller bend radii for medium-to-high pressure applications. In contrast, wire-spiral hoses (such as EN 856 4SH or SAE 100 R12) wrap multi-layer steel wires in parallel spiral wraps around the inner tube. This design handles extreme pressure spikes (surge pressure) and continuous impulse cycles without structural wire-frictional breakdown, making spiral hoses ideal for heavy mining equipment and excavator hydraulics in the Grenville market.
Every batch of hydraulic hoses produced in our facility undergoes rigorous hydrostatic proof testing (1.5x working pressure) and burst testing (4:1 safety factor compliance). Product reels are tightly wrapped with UV-protective poly-film and packed into heavy-duty wooden crates or steel frames to prevent atmospheric degradation, cover moisture damage, or deformation during trans-oceanic shipping to regional Grenville distribution hubs.
