Core Features & Technical Advantages

Heavy-Duty High-Tensile Steel Wire Reinforcement

The core strength of our DIN EN853 2ST High Pressure Steel Wire Braided Rubber Hose lies in its dual high-tensile steel wire braid reinforcement, engineered to withstand extreme pressure fluctuations and high-impulse hydraulic cycles common in heavy industrial equipment. This reinforced structure supports working pressures up to 415 bar (6018 PSI) for 3/16" diameters, with a mandatory 4:1 burst pressure safety ratio and 2.4x working pressure proof rating, ensuring maximum protection against catastrophic failure in high-stakes mining and engineering applications. The braided design also delivers superior fatigue resistance, extending service life even under continuous heavy load operation.

Multi-Environment Resistant Material Engineering

This heavy duty steel wire braided hydraulic hose is formulated with a high-performance inner tube that offers exceptional compatibility with both petroleum-based and water-based hydraulic fluids, resisting swelling, degradation, and fluid permeation even in high-temperature continuous use. The outer cover is specially engineered for extreme abrasion, weather, and impact resistance, standing up to rock contact, dust, moisture, and UV exposure in underground mining, outdoor construction, and remote exploration sites. This robust material design minimizes maintenance frequency and reduces total cost of ownership for heavy industrial operators.

Global Standard Compliance for Universal Compatibility

Our high tensile steel wire reinforced hydraulic hose is fully compliant with a wide range of international standards, including GB, DIN, RMA, AS, JIS, and SABS, ensuring seamless compatibility with global equipment designs and regional regulatory requirements. This multi-standard certification makes it an ideal choice for multinational equipment manufacturers and cross-border industrial projects, eliminating compatibility concerns and simplifying procurement for global supply chains. Every hose is rigorously tested to meet these standards, ensuring consistent quality across every production batch.

Applications & Industry Use Cases

Our mining machinery hydraulic hose is optimized for the most demanding heavy industrial hydraulic applications, with core use cases including:

Mining & Underground Machinery Systems

Purpose-built for underground mining equipment, hydraulic roof supports, coal mining machinery, and mineral processing equipment, where it delivers reliable performance in high-pressure, high-impulse hydraulic circuits operating in dusty, abrasive underground environments.

Heavy Engineering & Construction Machinery

Ideal for large-scale engineering equipment, including crawler cranes, piling rigs, and concrete pumping machinery, where it withstands extreme pressure loads, frequent movement, and harsh outdoor job site conditions.

Oil & Gas Exploration & Metallurgical Equipment

Widely used in onshore oil and gas exploration equipment, forging presses, and metallurgical machinery, with high-temperature resistance and pressure stability that supports continuous operation in high-heat, high-stress industrial environments.

FAQ

Q1:What standards does this high-pressure steel wire braided hose meet, and why does that matter?

A1:

The hose complies with SAE 100R1AT and EN 853 1SN, along with international standards including GB, DIN, RMA, AS, JIS, and SABS. This multi-standard certification ensures consistent quality, safety, and compatibility for global use in hydraulic systems conveying petroleum or water-based fluids. It gives buyers confidence in reliable performance under high pressure in demanding applications like mining equipment, oil exploration, and construction machinery.

Q2:How does the single steel wire braid provide strength for high-pressure hydraulic applications?

A2:

The reinforcement consists of one layer of high-tensile steel wire braid, which delivers excellent pressure resistance (working pressures from 250 bar / 3625 PSI in smaller sizes down to 40 bar / 580 PSI in larger ones) while maintaining good flexibility. Combined with the oil-resistant synthetic rubber inner tube and abrasion/weather-resistant cover, this single-braid design offers a balanced solution for high-pressure hydraulic oil lines in engineering construction, cranes, and metallurgy where impulse and durability are essential.

Q3:What burst and proof pressure safety features are included in this hose?

A3:

Burst pressure is rated at a 4:1 safety ratio (e.g., 1000 bar burst for 3/16" at 250 bar WP, 160 bar burst for 2" at 40 bar WP), and proof pressure is approximately 2.4× WP (e.g., 600 bar proof for smaller sizes). These safety margins protect against over-pressurization or surges common in mining support systems, forging equipment, and heavy-duty hydraulic circuits, helping prevent failures and ensuring safer operation.

Q4:How does the hose's weight and flexibility support practical use in heavy equipment?

A4:

Weight per meter ranges from 0.28 kg/m for smaller diameters (3/16"–1/4") to 2.25 kg/m for 2" sizes, keeping handling manageable in mobile applications like crane transport or mining tools. Minimum bend radius varies from 89 mm (3/16") to 635 mm (2"), allowing reasonable routing flexibility in confined spaces while the single braid and synthetic rubber construction prevent kinking under pressure—ideal for installation and maintenance in construction or exploration setups.
