Concentric Hose For Fire Rescue Breaching Tools

Product Positioning

 

This product is the main supporting part of fire rescue breaching tools, specially designed for hydraulic fire rescue breaching equipment. The main task of the hydraulic power pack is to supply stable hydraulic oil, so that tools such as hydraulic shears and spreaders have steady and constant power support. Compared with general hydraulic hoses, the unique design of the concentric tube structure can fundamentally improve the operational stability and anti-interference ability of the hydraulic system, and effectively prevent hidden dangers such as oil leakage and poor gearbox during emergency rescue. It is an indispensable support part of fire emergency rescue, industrial high-pressure operation and other scenarios, which ensures operation safety and improves rescue efficiency with professional performance.

 

Exclusive Structure and Material Analysis

 

The 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, to ensure long-term stable operation in complex environments.

 

• Inner Layer Material (PA11/12)

Selected PA11/12 special material with high compatibility to hydraulic oil, which can prevent the chemical reaction between hydraulic oil and pipe wall, avoid oil pollution and ensure cleanliness of hydraulic system; Meanwhile, the inner wall of the inner layer is finely processed, smooth and burr-free, which effectively reduces the resistance during the oil flow, helps the rapid transmission of hydraulic oil and gains valuable time for emergency rescue.

 

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

Depending on the operating pressure required, the reinforcement layer can be selected from high-strength steel wire or aramid fibre. Both materials have excellent pressure resistance and tensile strength, which can stably bear 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.

 

• Exterior Layer Material (Polyurethane Wear Resistant):

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

 

 

Core Advantages 

•Unique Concentric Structure Design for Efficient Transfer:

Adopt accurate concentric forming technology, to ensure that the concentricity error of inner and outer pipes is controlled within a very small range, effectively reducing the eddy current phenomenon during oil flow, reducing the flow resistance, and improving the gearbox efficiency of hydraulic oil. The concentric structure can also improve the overall stability of the hose, avoid poor gearbox caused by hose distortion and deformation, ensure the rapid response of fire rescue breachin

 

•High-Pressure Resistance Superior for Better Safety Assurance:

The reinforcement layer is made of high strength materials and professional forming technology, which can stably withstand the working pressure of 730Bar, 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.

 

• Wide Flexibility for Easier Operation:

The overall flexibility of the hose is professionally adjusted, flexibly bendable and laying, and convenient to installation and operation in narrow and complex rescue sites or industrial sites. It does not need other 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 ageing, can be used in complex and harsh environments such as fire rescue, industrial operations for a long time. The service life is greatly improved compared with ordinary hydraulic hose, which effectively reduces the replacement cost and operation interruption risk of the customer.
