EN856-4SP high-pressure oil pipe
EN856-4SP high-pressure oil pipe is a high-pressure hydraulic hose that complies with the European standard EN856-4SP. It consists of an inner rubber tube, four layers of high-strength steel wire reinforcement and an outer rubber covering layer.
EN856-4SP high-pressure oil pipe has the following characteristics and parameters:
1. High pressure capability: EN856-4SP hose can withstand extremely high working pressure. Its rated pressure is usually 380-450 bar, and the burst pressure can reach up to 1800 bar. It is suitable for working environments that need to withstand high pressure in high-pressure hydraulic systems.
2. Pulse resistance: Due to the design of four high-strength steel wire reinforcement layers, EN856-4SP hose has excellent pulse resistance and can withstand frequent hydraulic pulses and vibrations, extending the service life of the hose.
3. Wear resistance: The outer layer of the hose is covered with rubber, which can provide good wear resistance, resist friction and wear from external objects, and extend the service life of the hose.
4. Corrosion resistance: The inner rubber tube has good corrosion resistance and can withstand corrosion from various liquid media. It is suitable for working environments in chemical, petroleum and other industries.
5. Bending performance: Although EN856-4SP hose is a high-pressure steel wire reinforced rubber pipe, it also has certain bending performance and can adapt to a certain bending radius, making it easy to use in complex working environments.
It should be noted that when using EN856-4SP high-pressure oil pipe, the following precautions should be observed:
1. Regular inspection: Regularly check the appearance of the hose, including whether it is worn, aged, cracked, etc., and replace or repair problematic hoses in a timely manner.
2. Temperature limitations: The operating temperature range of hoses is generally -40°C to +100°C, and hoses should not be used at temperatures outside this range.
3. Avoid overpressure: When using hoses, ensure that the working pressure of the hose does not exceed its rated pressure to avoid accidents caused by hose rupture or explosion.
4. Avoid bends: The bending radius of the hose should comply with regulations to avoid damage to the hose caused by bends.
All in all, EN856-4SP high-pressure oil pipe is a hydraulic hose with high-pressure capability, pulse resistance, wear resistance, corrosion resistance and high strength. When using it, you need to pay attention to regular inspections, observing temperature limits, avoiding overpressure and bending, etc. to ensure safe and reliable operation of the hose.
