Steel Wire Spiraled Hydraulic Hose

Specifications for Steel Wire Spiraled Hydraulic Hose

Our extensive range of steel wire spiral hydraulic hose is designed to provide reliable Service in the most challenging environments. Below are the detailed technical aspects of our core product line.

1. Size Range: We manufacture hoses ranging from 3/8 inch to 2 inch internal diameter, accommodating a wide spectrum of flow and pressure requirements. For specialized needs, we also offer small steel wire spiral hydraulic hose and long steel wire spiral hydraulic hose up to 50 ft and beyond.

2. Working Pressure: Engineered to handle extreme forces, our hoses operate effectively at pressures up to 6000 psi, with some specialized 4 wire hydraulic hose pressure rating reaching even higher thresholds. The 2 wire hydraulic hose pressure rating typically covers lower pressure ranges within this spectrum.

3. Pressure Performance: Each hose is designed with a minimum burst pressure four times the maximum working pressure (4:1 safety factor), ensuring a substantial margin of safety against unexpected pressure spikes.

4. Construction & Materials:

   • Inner Tube: Made from oil-resistant synthetic rubber (e.g., NBR), ensuring compatibility with hydraulic fluids and fuels. The smooth bore minimizes pressure drop and fluid turbulence.

   • Reinforcement Layer: The core feature. It consists of multiple layers of high-tensile spiral steel wire. This construction, detailed in our hydraulic hose catalogue pdf, provides superior strength and resistance to the constant flexing and impulsive forces in high-cycle applications. This differentiates it from a standard 2 wire hydraulic hose or woven hose.

   • Outer Cover: A robust layer of abrasion, ozone, and weather-resistant synthetic rubber (e.g., CR). We offer options like protective sleeves and guards for added durability in extreme environments.

5. Fittings & End Connections: We provide a complete system, including compatible hydraulic hose end fittings. Options include crimped fittings for a permanent, leak-proof Assembly, reusable fittings for field repairs, and various adapters and flanges to connect to any system.

6. Applicable Standards: Our hoses are manufactured to meet or exceed leading global standards, including SAE 100R12, SAE 100R15, and EN 856 4SP/4SH, guaranteeing interchangeability and performance.

7. Performance Characteristics:

   • Pulse Performance: Tested to withstand over 400,000 impulse cycles under extreme pressure conditions, far exceeding industry requirements.

   • Temperature Range: Suitable for continuous operation from -40°F to +250°F (-40°C to +121°C), handling both high and low-temperature fluids.

   • Flexibility & Bend Radius: Despite its high-pressure rating, the spiral design offers excellent flexibility with a tight minimum bend radius, simplifying installation in confined spaces.

   • Media Compatibility: Excellent resistance to petroleum-based hydraulic oils, water glycol, lubricating oils, and diesel fuels.

To meet the diverse needs of the market, our Wire Spiral Hose is available in several specialized constructions. When you buy steel wire spiral hydraulic hose from HENGHUA, you are selecting a product tailored to your exact application.

1. Standard SAE 100R12 & 100R15 Hoses: These are the workhorses of the industry. An SAE 100R12 hydraulic spiral hose is designed for high-pressure service with four layers of spiral wire. The 100R15 series is built for even higher pressures, often utilizing four or six layers of heavy-gauge wire. They are the go-to replacement choice for construction and mining equipment. You can find detailed specifications for our Gates 2 wire hydraulic hose equivalents and 4SP/4SH ranges in our downloadable pdf catalog.

2. EN 856 4SP & 4SH Hoses: Meeting European norms, these hoses offer a compact design. The 4SP features a single wire braid and four spiral layers, while the 4SH has an extra layer of intermediate wire. They are ideal for applications where space is limited but high pressure is required, such as in air compressor parts & accessories and mobile hydraulics.

3. Extreme High-Pressure Hoses (R13 & R15): For the most demanding applications like vehicle brake lines and heavy-duty injection molding machines, our R13 and R15 series hoses deliver. They are engineered with multiple layers of spiral wire and a heavy-duty cover to handle up to 10,000+ psi, ensuring maximum safety and durability. If you are looking for new steel wire spiral hydraulic hose for a critical application, this is your solution.

4. Specialty & Custom Hoses: We understand that standard solutions don’t always fit. We offer hoses with specialized covers for extreme abrasion resistance, ultra-high flexibility for tight routing, and flame-resistant compounds. As a flexible distributor and wholesaler, we can provide custom lengths, colors, and even branding (OEM ODM) to meet your specific project needs.
