In the fields of industry, engineering machinery, mining equipment, etc., high-pressure hydraulic hoses are the core components of hydraulic systems, and their quality is directly related to the stability and safety of equipment operation. Once the wrong hose is selected, it may cause pipe bursting, oil leakage, equipment shutdown, and even cause safety accidents, resulting in huge economic losses. So, how to choose a safe and reliable high-pressure hydraulic hose? This article will analyze 5 key indicators for you and recommend the industry-leading LETONE brand to help you stay away from safety hazards!
1. Pressure resistance level: match working pressure to avoid pipe bursting risks
The core indicator of high-pressure hydraulic hoses is pressure resistance, and it must ensure that its working pressure (WP) and burst pressure (BP) meet system requirements.
Working pressure: The maximum pressure that the hose can withstand for a long time should be slightly higher than the maximum pressure of the system.
Burst pressure: The ultimate pressure bearing capacity of the hose is usually 34 times the working pressure.
LETONE high-pressure hydraulic hoses use high-strength steel wire braiding/winding layers with a wide pressure resistance range, up to 6000PSI or more, to ensure safe operation under extreme working conditions.
2. Material selection: oil-resistant, wear-resistant, and anti-aging
Hydraulic oil is corrosive, and inferior hoses are prone to expansion, cracking, and leakage. Therefore, the inner rubber layer of the hose must be made of oil-resistant synthetic rubber (such as NBR), and the outer rubber layer must have wear-resistant and UV-resistant properties.
Advantages of LETONE hoses:
Inner layer: high-purity nitrile rubber (NBR), excellent oil resistance, and anti-swelling.
Outer layer: wear-resistant composite rubber, tear resistance, strong weather resistance, and extended service life.
3. Bending radius: flexible adaptation to complex working conditions
Too small a bending radius of the hose will cause fatigue fracture of the steel wire layer and increase the risk of pipe explosion. When selecting, it is necessary to match the movement trajectory of the equipment to ensure that the hose can bend freely without deformation.
LETONE solution:
Optimize the structural design and provide small bending radius models for narrow spaces.
Highly flexible steel wire layer, anti-kinking, and reduce stress concentration.
4. Connector quality: prevent oil leakage and ensure sealing
Connector detachment or oil leakage is a common fault. Poor-quality connectors can cause hydraulic oil leakage and system pressure drop. High-quality hoses should be equipped with high-precision crimping connectors to ensure 100% sealing.
Advantages of LETONE connectors:
Carbon steel/stainless steel material, corrosion-resistant and vibration-resistant.
Precision crimping process to prevent loosening and leakage.
5. Certification standards: Comply with international safety regulations
Hoses must pass ISO, SAE, DIN and other certifications to ensure that their pressure resistance, pulse resistance, temperature resistance and other performance meet the standards. Uncertified products may have serious safety hazards.
LETONE certification:
ISO 18752, SAE J517 and other international standard certifications.
MSHA (Mine Safety Certification), suitable for harsh environments.
