Core Features & Technical Advantages

Consistent High Pressure Performance for Large Bore Sizes

A key differentiator of this large diameter high pressure spiral hydraulic hose is its ability to maintain a uniform working pressure of 350 bar (5075 PSI) across all sizes, from 3/4" up to a 2" inner diameter. Unlike standard hoses that lose pressure capacity as bore size increases, this design ensures reliable high-pressure performance even for large-volume fluid transfer applications. It adheres to a rigorous 4:1 burst-to-working pressure safety ratio, with an 830 bar proof pressure and 1400 bar burst pressure, delivering exceptional structural stability and safety for continuous heavy-duty operation.

Robust Spiral Reinforcement for Dynamic Load & Surge Resistance

The multi-layer high-tensile steel wire spiral construction of this 350 bar hydraulic hose for heavy duty systems provides superior resistance to pressure surges, impulse loads, and repeated flexing, outperforming braided hose alternatives in dynamic hydraulic environments. The premium synthetic rubber inner tube offers excellent compatibility with petroleum-based hydraulic fluids, minimizing degradation and extending service life, while the heavy-duty outer cover resists abrasion, ozone, and weather damage in rugged outdoor and industrial settings. This robust build ensures consistent performance even in systems with frequent pressure fluctuations and continuous movement.

Scalable Design for Flexible Installation in Large Equipment

Designed for practical integration into large-scale hydraulic setups, this constant pressure hydraulic hose for mining equipment features size-optimized minimum bend radii and weight specifications that balance structural strength with installation flexibility. With a minimum bend radius ranging from 240 mm for 3/4" sizes up to 630 mm for 2" sizes, and a weight range of 1.65 kg/m to 6.9 kg/m, it supports straightforward routing in large heavy equipment, reducing installation stress on the reinforcement layers and ensuring long-term durability in high-cycle operations.

Applications & Industry Use Cases

This SAE 100 R13 hydraulic hose is purpose-built for high-pressure hydraulic systems subject to surge, flexing, and high-volume fluid transfer requirements. Core applications include large-scale surface and underground mining machinery, heavy construction equipment with high-flow hydraulic circuits, industrial hydraulic power units, off-highway equipment maintenance and retrofit projects, and high-performance industrial hydraulic systems requiring large-bore hose solutions. It is the go-to choice for users who need consistent high-pressure performance in larger diameter configurations, without compromising on durability or surge resistance.

FAQ

Q1:What reinforcement design gives the SAE 100R13 hose its ultra-high pressure capability across large sizes?

A1:

The hose uses four or six layers of high-tensile steel wire spiral reinforcement, providing exceptional strength and resistance to pressure surges or flexing. With an oil-resistant synthetic rubber inner tube and abrasion/weather-resistant cover, this multi-spiral construction supports a constant working pressure of 350 bar / 5075 PSI from 3/4" to 2" sizes, making it suitable for demanding high-pressure hydraulic systems in mining and construction equipment.

Q2:How do the constant pressure ratings and safety factors perform in surge-prone applications?

A2:

Working pressure remains steady at 350 bar / 5075 PSI across all listed sizes (3/4" to 2"), with proof pressure at 830 bar and burst pressure at 1400 bar (strict 4:1 safety ratio). This uniform high-pressure rating, combined with the spiral design's superior surge and impulse resistance, ensures reliable performance in very high-pressure systems subject to frequent flexing or pressure spikes, such as heavy construction machinery or mining operations using petroleum-based hydraulic fluids.

Q3:Why does the SAE 100R13 hose maintain consistent pressure in larger diameters?

A3:

Unlike many hoses where pressure drops significantly with size, the multi-spiral steel wire reinforcement (four or six layers) allows a constant 350 bar / 5075 PSI working pressure even in large bores (up to 2" ID / 50.4–52.0 mm). This enables high flow rates at extreme pressures without needing oversized alternatives, ideal for high-performance industrial or mining applications requiring large-volume fluid transfer under demanding conditions.

Q4:How does the weight and bend radius scale for installation in heavy-duty systems?

A4:

Weight per meter increases with size: 1.65 kg/m for 3/4", 2.25 kg/m for 1", up to 6.9 kg/m for 2". Minimum bend radius also scales: 240 mm for 3/4", 300 mm for 1", up to 630 mm for 2". These values support robust handling in large equipment while requiring adequate space for routing to avoid stress on the spiral layers—ensuring long-term durability in high-pressure, surge/flexing environments like construction or mining hydraulics.
