en 856-4sp 32 four-layer steel wire wound high pressure hose
On November 3, 2024, the Hydraulic Hose Division of LETONE Technology will discuss in depth the basic characteristics and application areas of the EN 856-4SP 32 four-layer wire-wound high-pressure hose. EN 856-4SP is a hydraulic hose model specified by the International Organization for Standardization, which is particularly suitable for high-pressure working environments. 32 usually refers to the inner diameter of the hose. The four-layer wire winding structure gives this hose extremely high compressive strength and wear resistance, making it an indispensable and important component in many industrial fields.
The structural design of the four-layer wire-wound high-pressure hose is very precise. It consists of an inner layer, a middle layer, an outer layer and four layers of wire winding. The inner layer is usually made of oil-resistant and wear-resistant synthetic rubber material, which is responsible for direct contact with the transmitted hydraulic fluid to ensure the purity and transmission efficiency of the fluid. The middle layer is usually one or more layers of fiber or rubber reinforcement layers to provide additional strength and stability. The outer layer is another layer of oil-resistant and weather-resistant synthetic rubber, which mainly plays a protective role to prevent the external environment from damaging the inside of the hose. The most critical part is the four-layer steel wire winding layer. These steel wires are tightly wound between the inner and outer layers at a specific angle and tension, forming an indestructible barrier that can withstand extremely high working pressures and prevent the hose from expanding or bursting under high pressure.
In terms of material selection, this high-pressure hose usually uses high-quality rubber and steel wire. The rubber material not only needs to have excellent oil resistance, wear resistance and weather resistance, but also needs to have a certain elasticity and flexibility to adapt to complex and changing working environments. The steel wire needs to have high strength and good corrosion resistance to ensure that the hose will not fail due to rust or breakage of the steel wire during long-term use.
The operating temperature range of EN 856-4SP 32 four-layer steel wire winding high-pressure hose is usually wide, and it can maintain stable performance in extreme environments. Generally speaking, this hose can work normally in the temperature range of -40℃ to +100℃ (even higher temperatures in some special models). This is due to its high-quality rubber material and precise manufacturing process, which enables the hose to maintain its stable physical and chemical properties under various harsh working conditions.
In terms of application areas, EN 856-4SP 32 four-layer steel wire wound high-pressure hose covers almost all industrial fields that require high-pressure hydraulic transmission. For example, in the field of engineering machinery, large excavators, cranes, rollers and other equipment widely use this hose to transmit hydraulic oil to ensure the normal operation of the equipment. In port loading and unloading equipment, this hose also plays an important role, providing stable and reliable hydraulic power for loading and unloading machinery. In addition, in industries such as oil drilling, metallurgy, and mining, this high-pressure hose is also favored for its excellent pressure resistance and wear resistance.
In the specific application process, EN 856-4SP 32 four-layer steel wire wound high-pressure hose shows its unique advantages. First, its extremely high compressive strength enables it to work stably for a long time under high-pressure environment without leakage or rupture. Secondly, due to the use of a four-layer steel wire winding structure, the wear resistance of this hose has also been significantly improved, and it can maintain a long service life even in harsh working environments. In addition, this hose also has good flexibility and bending performance, and can adapt to various complex pipeline layouts and installation requirements.
However, despite the many advantages of EN 856-4SP 32 four-layer steel wire wound high-pressure hose, some matters need to be paid attention to in actual use to ensure the stability and safety of its performance. First, excessive bending and twisting of the hose should be avoided during installation to avoid damage to the internal structure of the hose. Secondly, the appearance and performance status of the hose should be checked regularly during use, and if abnormalities are found, they should be replaced in time to avoid safety accidents. In addition, during storage and transportation, care should be taken to avoid damage to the hose by high temperature, humidity and corrosive substances.
In terms of production technology, the production process of EN 856-4SP 32 four-layer steel wire wound high-pressure hose is very complicated and requires high-precision equipment and technical support. From the selection of raw materials to mixing, extrusion, winding, vulcanization and other production links, strict control of quality and technical parameters are required to ensure the performance and quality of the final product. For example, during the extrusion process, the extrusion speed and temperature of the rubber need to be precisely controlled to ensure the uniformity and thickness of the inner layer; during the winding process, the tension, angle and spacing of the steel wire need to be precisely controlled to ensure the stability and strength of the winding layer; during the vulcanization process, the vulcanization temperature and time need to be precisely controlled to ensure the stability of the physical and chemical properties of the hose.
With the continuous advancement of industrial technology and the continuous expansion of application fields, EN 856-4SP 32 four-layer steel wire wound high-pressure hose is also constantly developing and improving. On the one hand, in order to meet the needs of different industries and application scenarios, the material and structural design of the hose are constantly optimized and improved; on the other hand, as the concepts of environmental protection and sustainable development are deeply rooted in the hearts of the people, more and more environmentally friendly materials and production processes are introduced into the production process of the hose to reduce the impact on the environment.
In short, EN 856-4SP 32 four-layer steel wire wound high-pressure hose plays a pivotal role in the industrial field with its excellent pressure resistance, wear resistance and flexibility. It can be seen in industries such as engineering machinery, port loading and unloading equipment and oil drilling. With the continuous advancement of technology and the continuous expansion of application areas, we have reason to believe that this high-pressure hose will continue to play a more important role in the future and make greater contributions to the industrial development of human society. At the same time, we should also continue to pay attention to the improvement and innovation of its production process and environmental performance to promote its development in a more efficient, environmentally friendly and sustainable direction.
