The Rise of Hydraulic Hose China Manufacturing
Hydraulic hose China production has become the global standard for cost-effective, high-quality flexible hose assemblies used in construction equipment, mining, agriculture, manufacturing, and mobile hydraulics. Chinese hydraulic hose manufacturers produce over 70% of the world's supply, combining massive scale (20M+ meters/year per major factory) with adherence to SAE J517, EN 856, and ISO standards.
A professional hydraulic hose manufacturer invests in spiral (4SH/4SP) and braided (R1AT/R2AT) lines, imported test equipment (impulse testers per SAE J343, tensile machines), and CNC fittings production. Qingdao VIH Hose Co., Ltd exemplifies this with 40,000 sqm facility, 200+ staff, 7 spiral + 24 braiding lines (3/16"-4"), and comprehensive R&D/testing center.
Key Questions Hydraulic Hose Customers Always Ask
1. What are the main types of hydraulic hoses?
Textile Braided (R1AT/R2AT, EN 1SN/2SN):
-
1-braid: 200-350 bar WP
-
2-braid: 400 bar WP
-
Applications: Low-medium pressure mobile hydraulics
Wire Spiral (R12/R13/R15, EN 4SH/4SP):
-
4SP: 420-700 bar WP
-
Applications: High-pressure mining, cranes, presses
Special Hoses: Petroleum drilling (API), yellow air hose, flame-retardant.
2. What standards should hydraulic hoses meet?
Global Standards:
| Standard | Construction | Max WP | Impulse Cycles (SAE J343) |
|---|---|---|---|
| SAE 100R1AT | 1-braid | 350 bar | 200K @ 1Hz |
| SAE 100R2AT | 2-braid | 400 bar | 400K @ 1Hz |
