EN856-4SH Hydraulic Hose Selection Guide
In the field of heavy machinery, high-pressure hydraulic hoses are indispensable key components. They are responsible for transmitting high-pressure liquids under extreme conditions to ensure the stable operation of mechanical equipment. Today, we will take a deep look at the high-pressure hydraulic hoses of the EN856-4SH standard, and especially recommend the LETONE brand 4SH high-pressure hydraulic hose and its hose assembly to help you better understand and choose the high-pressure hose suitable for your equipment.
I. Overview of EN856-4SH High-Pressure Hydraulic Hose
EN856-4SH is a hydraulic hose standard jointly formulated by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN). The standard specifies the structure, performance, test methods and marking requirements of four-layer steel wire winding high-pressure hoses. This hose has been widely used in high-pressure and large-flow hydraulic systems such as engineering machinery, ships, and aerospace due to its high strength, high pressure resistance, oil resistance, and temperature resistance.
The structure of the EN856-4SH high-pressure hydraulic hose is usually composed of an inner rubber layer, a middle rubber layer, a four-layer high-strength steel wire winding reinforcement layer, and an outer rubber layer. The inner rubber layer is made of oil-resistant and wear-resistant rubber material to ensure the purity of the transmission medium and the stability of the system. The middle rubber layer acts as a transition layer, which enhances the bonding strength between the inner and outer rubber layers. The four-layer high-strength steel wire winding reinforcement layer is the core part of the hose, which provides the hose with the ability to withstand high pressure. The outer rubber layer protects the steel wire layer from external damage, while giving the hose good wear resistance and weather resistance.
