In hydraulic, pneumatic, and fluid transfer systems, hoses are often regarded as the “blood vessels”. Among the components of hoses, the reinforcement layer is the most crucial part, as it directly determines the hose’s pressure resistance, flexibility, and service life. Selecting the right reinforcement layer not only ensures the stable operation of the system but also reduces maintenance costs and enhances overall safety.
The reinforcement layer serves as the “skeleton” of the hose. It bears pressure, resists explosion, and maintains structural stability when the fluid exerts high-pressure impact, bending stress, and frequent pulsations. If the wrong type is chosen, it may lead to frequent oil leakage and hose bursting, increasing downtime losses at best; at worst, it could cause equipment accidents and even personal injuries. Therefore, appropriate reinforcement layer structures must be selected for different industries, pressure levels, and usage scenarios.
There are several common types of reinforcement layers, each with distinct characteristics and applications. Steel Wire Braid, featuring excellent flexibility and moderate weight, is suitable for occasions requiring frequent bending, widely used in construction machinery, hydraulic equipment, and architectural machinery. Steel Wire Spiral, with strong high-pressure resistance and pulse resistance, is ideal for heavy loads and applied in mining, oil fields, heavy-duty equipment, and metallurgical industries.
Textile Braid, being lightweight and soft, is suitable for low-pressure medium transfer, commonly used in air compressors, water pipes, agricultural irrigation, and low-pressure oil circuits. Textile Spiral, with medium pressure resistance, light weight, and non-conductivity, offers high safety and is applied in aerospace, rail transit, and lightweight equipment. Hybrid Reinforcement, combining fibers and threaded steel wire support, balances high-pressure bearing and flexibility, used in high-pressure cleaning, fire protection, special industrial hoses, oil suction, and oil return discharge pipes. Spiral Plastic Helix, with an anti-collapse structure, is mainly used in suction and discharge negative pressure working conditions, such as agricultural water suction pipes, oil suction pipes, and chemical suction and discharge pipes.
For different industries, specific recommendations are provided. The engineering machinery/hydraulic industry prioritizes Steel Wire Braid and Steel Wire Spiral to ensure the safety and stability of high-pressure hydraulic systems. The mining, oil field, and metallurgical industries benefit more from Steel Wire Spiral, which can withstand high pressure and pulse impact. The agricultural and municipal sectors prefer Textile Braid and Spiral Plastic Helix reinforcement types for their light weight and durability, suitable for water and low-pressure media. The aerospace, rail transit, and high-end equipment industries opt for Textile Spiral due to its lightweight and non-conductive properties, meeting safety requirements. The special equipment and industrial cleaning fields rely on Hybrid Reinforcement hoses to balance high pressure and flexibility.
Although the reinforcement layer is hidden inside the hose, it determines the “vitality” of the hose. Choosing the right reinforcement layer means choosing safety and efficiency. By reasonably selecting the reinforcement layer structure based on different working pressures, medium characteristics, and industry needs, enterprises can ensure stable system operation, reduce losses, and achieve more efficient productivity.
