Hydraulic hoses play a critical role in various industrial applications, providing the necessary means to transmit hydraulic fluids. One of the established standards governing the manufacturing and testing of hydraulic hoses is EN 857. Specifically, EN 857 1SC pertains to a class of hydraulic hoses designed to operate under specific conditions of pressure and temperature. This article will delve into the intricacies of the EN 857 1SC standard, its construction, applications, and significance.


When it comes to vehicle maintenance, one often overlooked component is the brake hose. These flexible tubes play a critical role in the braking system, transmitting brake fluid from the master cylinder to the brake calipers. Ensuring that your brake hoses are in good condition is essential for the safety and performance of any vehicle. However, the cost associated with brake hoses can vary widely, making it crucial for vehicle owners to understand the factors influencing these costs.


Hydraulic rubber hoses are composed of several layers, each serving a unique purpose. The innermost layer is usually made of synthetic rubber, which is designed to withstand the pressure of the hydraulic fluids. This inner lining is often resistant to various chemicals, ensuring longevity in harsh operating environments. The next layer typically consists of reinforcement fabric or braided steel wires, enhancing the hose's strength and flexibility while preventing it from bursting under pressure.


In the agricultural industry, hydraulic systems are commonly found in tractors and other farming equipment. Here, hand crimpers aid farmers in maintaining and repairing hoses that are subject to wear and tear, especially when exposed to harsh environmental conditions. This capability not only boosts the efficiency of farming operations but also enhances safety by reducing the likelihood of hydraulic failures.


4. Chemical Resistance Industrial environments can expose hoses to various chemicals. The materials used in manufacturing high pressure steam hoses should possess adequate resistance to the chemicals that may come into contact with the hose.


2. Pressure Rating Always check the pressure rating of the hose to guarantee it can handle the operational pressures of your system.


1. Efficiency The ability to utilize high pressures allows for faster operation and productivity in industrial processes.

Auto fuel hoses are designed to withstand the harsh conditions that come with transporting gasoline, diesel, or alternative fuels. Constructed from durable materials like rubber, reinforced with steel or fabric, these hoses are engineered to resist high temperatures, pressure, and various chemicals found in fuels. Additionally, they are designed to be flexible, which is essential for navigating the tight spaces within an automotive system.


- Regular Inspection Routine inspections of pipeline integrity and connections are essential. Look for signs of wear, corrosion, or damage that could compromise the system.


2. Type of Vehicle The make and model of a vehicle can significantly influence brake hose prices. Specialty vehicles or high-performance cars often require specific hoses that can withstand greater stress and heat, leading to higher costs. On the other hand, standard vehicles may have more affordable options available.


- Speed and Efficiency Automated and electric crimpers can significantly speed up the production process, making it easier to meet high-demand requirements.

The EN 857 1SC standard provides specifications not only for pressure but also for temperature. The hose is designed to perform efficiently in a temperature range of -40°C to +100°C (-40°F to +212°F). This broad temperature range ensures that the hoses remain functional in various environmental conditions, from extremely cold to moderately hot climates.


Les flexibles de frein sont souvent négligés, mais ils sont essentiels au bon fonctionnement des systèmes de freinage. Ils doivent non seulement être résistants à la chaleur et à la pression, mais aussi capables de supporter les vibrations et les mouvements du véhicule. Un flexible de frein usé ou endommagé peut entraîner des fuites de liquide de frein, compromettant l'efficacité du système de freinage et mettant en danger la sécurité des passagers.


Applications of Blue Air Hoses


- Replace hoses that show signs of deterioration to prevent system failures.

Since hose may change in length from +2% to -4% under the surge of high pressure, provide sufficient slack for expansion and contraction.
Never use a bending radius less than the minimum shown in the hose specification tables. The bending radius of the hose should be far away from the hose fitting (A>1.5R)
Hose bending radius is bigger when it is in motion.
Choose proper fittings, avoid twisting in hose lines bent in two planes.
Avoid twisting in hose by use clamp properly.
Hose should not be twisted, hose is weak when installed in twisted position. Also pressure in twisted hose tends to loosen fitting connections. Design so that machine motion produces bending rather that twisting.
Leave proper length when the hose in connected
Choose proper fittings, avoid too small bending radius and excess force.
Choose proper fittings, avoid excessive hose length.
Reuse friction, avoid hose touching the object directly or far away from the object.
Hose Active Working Pressure Working Life
As shown , when active working pressure in 1.25 times recommended working pressure, the hose working life is only half of i under working in recommended working pressure.
Store Conditions of the Assembly.
1.If possible, the storing temperature range is within 0-30 ℃. During storing, temperature should not exceed 50℃
2.The storing areas can not place equipment within can produce ozone.For example mercury vapour lamp, high voltage electric device and other equipment which can produce spark or set out electricity.
3.Can not be placed with erosive products or exposed over gas-volatile on these products.
4.Far away from heat source and equipment which can produce electric field or magnetic field
5.Avoid sunshine or strong artificial light source
6.Avoid to touch the sharp objects or the ground
7.Guarantee against rodent attacking.
8.Observe the rule of “First in, then first out”

Chức năng chính của ống điều hòa không khí là vận chuyển chất lạnh (thường là gas) từ nơi này đến nơi khác trong hệ thống điều hòa. Sau khi máy nén nén chất làm lạnh, ống sẽ dẫn chất này đến dàn ngưng để khí lạnh được chuyển hóa thành trạng thái lỏng. Chất lỏng sau đó được dẫn đến dàn bay hơi, nơi nó biến đổi trở lại thành khí và làm lạnh không khí trong khoang xe. Quá trình này lặp đi lặp lại, tạo nên một chu trình điều hòa không khí hiệu quả.


In conclusion, chemical resistant hoses are indispensable tools in safely managing and transporting hazardous substances across various industries. The right selection, proper maintenance, and vigilant safety measures ensure that these hoses perform reliably while minimizing the risk of chemical spills and exposure. As industries continue to evolve, the demand for high-quality, durable, and efficient chemical resistant hoses will only grow, emphasizing the importance of investing in the right equipment to protect both workers and the environment.

Crimping is the process of compressing a fitting around the end of a hose to create a secure and leak-proof seal. Unlike hose clamps, which can loosen over time or fail under pressure, crimped fittings provide a permanent bond that is less likely to degrade. This is particularly important in high-stress environments, where the consequences of a hose failure can be catastrophic.


The specification of hydraulic hoses sometimes denotes the percentage of reinforcement or operational efficiency. Moving from a 3% to a 4% hydraulic hose can reflect various improvements in performance, pressure ratings, and overall durability. Although this specification might not be standard across all manufacturers, increasing the percentage typically indicates that the hose has enhanced material properties, allowing it to handle greater pressures or more demanding applications.
