EN856 4SH four-layer steel wire spiral hose
In hydraulic systems, hoses play a vital role. They not only transmit fluid media, but also carry the pressure and power of the system. Among many hose products, EN856 4SH four-layer steel wire spiral hose is highly respected for its excellent performance and wide application fields. This article will introduce the characteristics of EN856 4SH four-layer steel wire spiral hose in detail, and especially recommend LETONE brand 4SH and 4SP hydraulic hoses, focusing on the advantages of LETONE4SH hose.
EN856 4SH four-layer steel wire spiral hose is a high-performance hydraulic hose that complies with European standard EN856-4SP (or equivalent standard) and has excellent pressure bearing capacity and wear resistance. The structural design of this hose is very exquisite, consisting of three parts: inner layer, four layers of high-strength steel wire spiral layer and outer layer. The inner layer is usually made of oil-resistant and wear-resistant synthetic rubber materials to ensure smooth medium transmission and sealing; the four layers of high-strength steel wire are tightly wound in alternating directions, providing excellent pressure-bearing capacity and burst resistance; the outer layer is made of oil-resistant and weather-resistant synthetic rubber materials, which effectively resist the erosion of the external environment and extend the service life of the hose.
As a leader in the field of hydraulic hoses, the 4SH and 4SP hydraulic hoses produced by the LETONE brand enjoy a high reputation in the market. LETONE4SH hoses not only strictly follow the EN856-4SH standard, but also carry out a number of technical innovations and optimizations on this basis, making the product more outstanding in performance and more widely used.
LETONE4SH hoses perform well in pressure bearing capacity. Due to the four-layer high-strength steel wire winding structure, the hose can withstand extremely high working pressure and maintain stable performance even under extreme working conditions. This excellent pressure bearing capacity makes LETONE4SH hoses an ideal choice for high-pressure hydraulic systems.
In terms of wear resistance, LETONE4SH hoses also perform well. The oil-resistant and weather-resistant synthetic rubber material on the outer layer can not only effectively resist the erosion of the external environment, but also maintain a low wear rate during friction. This means that the hose can maintain a good appearance and performance during long-term use, reducing the frequency of maintenance and replacement, and reducing the operating cost of the system.
In addition to excellent pressure bearing capacity and wear resistance, the LETONE4SH hose also has excellent flexibility. The four-layer steel wire winding structure allows the hose to have good bending performance while maintaining high strength. This allows the hose to easily adapt to various complex pipeline layouts during arrangement and installation, reducing pipeline connection points and installation difficulties, and improving the overall performance and reliability of the system.
In addition, the LETONE4SH hose is also easy to care for and maintain. The smooth surface design makes the hose surface smoother, less likely to accumulate dirt and impurities, and reduces the workload of cleaning and maintenance. At the same time, the smooth surface also makes it easier to find surface defects, find problems in time and deal with them, avoiding potential safety hazards.
In terms of application areas, the LETONE4SH hose also performs well. It is suitable for hydraulic systems using petroleum-based hydraulic oil, with a temperature range of -40℃ to +100℃, and can meet the use requirements under various harsh working conditions. Whether in oil drilling, construction machinery, shipbuilding or other industrial fields, LETONE4SH hose can perform excellent performance and provide strong guarantee for the stable operation of the system.
Compared with 4SH, LETONE's 4SP hydraulic hose also has excellent performance and a wide range of applications. The 4SP hydraulic hose is similar to the 4SH in structure, but has been optimized and improved in some aspects to meet different usage requirements. For example, the 4SP hydraulic hose may use a thicker inner or outer rubber layer to improve the sealing and wear resistance of the medium; or use steel wires of different materials to enhance the pressure bearing capacity and fatigue resistance of the hose. These optimizations and improvements enable the 4SP hydraulic hose to perform better under certain specific working conditions.
However, whether it is 4SH or 4SP hydraulic hose, the LETONE brand always adheres to quality as the core and technological innovation as the driving force to continuously launch better products and services. LETONE has advanced production equipment and a technical team, which can provide customers with customized solutions and all-round technical support. At the same time, LETONE has also established a complete after-sales service system to ensure that customers can get timely and effective help and support during use.
In summary, EN856 4SH four-layer steel wire spiral hose is a high-performance and high-reliability hydraulic hose product. As a leader in this field, the 4SH and 4SP hydraulic hoses produced by LETONE enjoy a high reputation in the market. LETONE4SH hose has become the first choice for many hydraulic system users with its excellent pressure bearing capacity, wear resistance, flexibility and easy care. In the future development, LETONE will continue to adhere to the principle of "quality first, customer first", and continue to launch more excellent products and services to provide strong support for the stable operation of hydraulic systems and the sustainable development of customers.
