Concentric Hose For Fire Rescue Breaching Tools

Product Positioning

As a core supporting component of fire rescue breaching tools, this product is tailor-made for hydraulic fire rescue breaching equipment. Its core function is to stably deliver hydraulic oil, providing continuous and reliable power support for tools such as hydraulic shears and spreaders. Different from ordinary hydraulic hoses, its exclusive concentric tube structure design fundamentally improves the operational stability and anti-interference ability of the hydraulic system, effectively avoiding hidden dangers such as oil leakage and poor transmission during emergency rescue. It is an indispensable key supporting part in fire emergency rescue, industrial high-pressure operation and other scenarios, safeguarding operation safety and improving rescue efficiency with professional performance.​

 Exclusive Structure and Material Analysis

This product adopts a three-layer composite structure design, and each layer of material is strictly selected to accurately adapt to the harsh working conditions of fire rescue, taking into account multiple characteristics such as pressure resistance, wear resistance and flexibility, ensuring long-term stable operation in complex environments.​

•Inner Layer Material (PA11/12):

Selected PA11/12 special material with high compatibility with hydraulic oil, which fundamentally prevents chemical reactions between hydraulic oil and the pipe wall, avoids oil contamination, and ensures the cleanliness of the hydraulic system; at the same time, the inner wall of the inner layer is finely processed, smooth and burr-free, effectively reducing the resistance during oil flow, helping the rapid transmission of hydraulic oil, and gaining valuable time for emergency rescue.​

•Reinforcement Layer (High-Strength Steel Wire/Aramid Fiber):

According to the operation pressure requirements, high-strength steel wire or aramid fiber can be selected as the reinforcement layer. Both materials have excellent pressure resistance and tensile strength, which can stably withstand the impact of high-pressure oil, effectively prevent the hose from bursting, bulging and other problems under high-pressure working conditions, completely avoid safety hazards during operation, and adapt to high-intensity operation scenarios such as fire rescue and industrial high pressure.​

•Outer Layer Material (Wear-Resistant Polyurethane):

The outer layer is made of wear-resistant, impact-resistant and scratch-resistant polyurethane material, which can effectively resist external damage such as sharp objects, gravel and friction at the rescue site. It also has good anti-aging performance, can adapt to different climatic environments, extend the service life of the hose, and reduce the maintenance cost and replacement frequency of customers.​

Core Advantages 

•Exclusive Concentric Structure Design for More Efficient Transmission:

Adopting precise concentric forming technology to ensure that the concentricity error of the inner and outer pipes is controlled within a very small range, effectively reducing the eddy current phenomenon during oil flow, reducing flow resistance, and improving the transmission efficiency of hydraulic oil; at the same time, the concentric structure can enhance the overall stability of the hose, avoid poor transmission caused by hose distortion and deformation, ensure the rapid response of fire rescue breaching tools, and adapt to the urgent needs of emergency rescue.​

•Outstanding High-Pressure Resistance for More Safety Assurance:

The reinforcement layer is made of high-strength materials, combined with professional forming technology, which can stably withstand 730Bar working pressure, fully adapt to the high-pressure and high-flow requirements of fire rescue and industrial high-pressure equipment, and still maintain good sealing performance under extreme high-pressure working conditions, preventing oil leakage and providing strong guarantee for the safety of operators.​

•Excellent Flexibility for More Convenient Operation:

The overall flexibility of the hose has been professionally adjusted, which can be flexibly bent and laid, facilitating installation and operation in narrow and complex rescue sites or industrial sites. It does not need additional complex tools, can quickly adapt to the installation angle of various fire rescue breaching tools, reduce operation difficulty and improve operation efficiency.​

•Wear and Damage Resistance for Longer Service Life:

Double wear-resistant protection of inner and outer layers, inner layer resistant to oil erosion, outer layer resistant to external damage and aging, can be used for a long time in complex and harsh environments such as fire rescue and industrial operations. Compared with ordinary hydraulic hoses, the service life is greatly improved, effectively reducing the customer's replacement cost and operation interruption risk.
