DIN EN856 SAE R13 R15
SAE 100 R13 and R15 are ultra-high pressure, six-layer wire-wound hydraulic hoses reinforced with multi-layer high-strength steel wire winding. They represent the highest pressure rating in the SAE 100R series, specifically designed for extremely harsh operating conditions, capable of withstanding extremely high system pressure, intense pressure shocks and pulses.
- Product Introduction
SAE 100 R13 and R15 are ultra-high pressure, six-layer wire-wound hydraulic hoses reinforced with multi-layer high-strength steel wire winding. They represent the highest pressure rating in the SAE 100R series, specifically designed for extremely harsh operating conditions, capable of withstanding extremely high system pressure, intense pressure shocks and pulses. These two types of hoses strictly comply with the SAE J343 standard and are the preferred choice for ultra-high pressure hydraulic systems in heavy construction machinery, mining equipment and large presses, etc.
Product Structure And Features
R13 and R15 have similar multi-layer composite structures, but the specific design of the steel wire winding layer determines their different performance emphases.
Inner rubber layer
Made of oil-resistant and wear-resistant synthetic rubber, it has excellent compatibility with petroleum-based hydraulic oil, bio-oil, etc., ensuring the purity and sealing of fluid transportation under high pressure.
Enhancement Layer (Core difference)
SAE 100 R13
Four or six layers of high-strength steel wire winding are adopted. Its steel wires are usually arranged in a "tightly wound" manner, which makes the outer diameter of the hose relatively smaller, lighter and more flexible, while performing well in maintaining ultra-high pressure resistance.
Enhancement Layer (Core difference)
SAE 100 R15
It also adopts four or six layers of high-strength steel wire winding layers. Its steel wires are usually wound at "regular intervals". This structure offers unparalleled resistance to pulse fatigue, making it particularly suitable for environments with severe pressure shocks and pulses, and it has an extremely long service life.
Outer rubber layer
Made of synthetic rubber that is super wear-resistant, weather-resistant and ozone-resistant. The thick and sturdy outer layer can withstand the harshest physical and environmental damage, providing ultimate protection for the internal steel wire reinforcing layer.
Core Features
Ultra-high pressure resistance
The multi-layer steel wire winding structure provides extremely high burst pressure and is suitable for ultra-high pressure systems.
Outstanding anti-pulse performance
Especially R15, which is designed to provide the best resistance to pressure shock and pulse fatigue, with an extremely long service life.
Outstanding flexibility
(R13 stands out)
The tightly wound structure of R13 achieves a smaller outer diameter and better flexibility at the same pressure level, facilitating installation in compact Spaces.
Ultimate durability
The super-strong outer rubber and steel wire frame can resist extreme wear and tear, impact and harsh environments.
Low bending radius
Despite being an ultra-high pressure hose, it still maintains excellent bending performance.
