High precision honing tubes are widely used in industrial fields that require high reliability, long lifespan, and precise control due to their excellent dimensional accuracy, surface smoothness, and material properties. The following is a detailed classification of its main uses and specific application scenarios:
1、 Hydraulic and pneumatic systems: Core transmission components
Hydraulic cylinder/cylinder barrel
Application scenarios: Hydraulic cylinders or cylinders for construction machinery (excavators, loaders), industrial equipment (injection molding machines, die-casting machines), and agricultural machinery (tractors, harvesters).
Advantage:
The inner wall roughness Ra ≤ 0.4 μ m reduces seal wear and extends service life (such as the use of 27SiMn honing tubes for mining hydraulic support cylinders, which can achieve 300000 times of expansion and contraction without leakage).
Straightness ≤ 0.25mm/m, ensuring smooth piston movement and avoiding jamming or leakage.
high-pressure fuel pipe
Application scenarios: hydraulic systems for construction machinery, ship servos, aerospace hydraulic devices.
Advantages: High pressure resistance (up to 100MPa), corrosion resistance, and prevention of oil oxidation or particle wear caused by rough inner walls.
Pneumatic control tube
Application scenarios: Automated production lines, robot joints, pneumatic tools.
Advantages: Smooth inner wall reduces airflow resistance, improves response speed, and reduces energy consumption.
2、 Construction machinery: Key moving components
Shock absorber tube
Application scenarios: automotive suspension systems, engineering machinery seat damping, and vibration isolation of building equipment.
Advantages: High precision inner holes ensure smooth piston movement, improve shock absorption and durability (such as using honing tubes for commercial vehicle shock absorbers, which extend their lifespan by 50%).
Steering system pipe
Application scenario: Hydraulic power steering system for heavy-duty trucks and construction machinery.
Advantages: High inner wall smoothness, reducing the risk of power steering oil leakage, and improving handling stability.
Telescopic arm/leg tube
Application scenarios: high-altitude work platforms, fire trucks, and on-board cranes.
Advantages: High straightness ensures synchronous expansion and contraction, avoiding the risk of jamming or overturning caused by deformation.
3、 Energy and chemical industry: Corrosion resistance and high voltage transmission
Petrochemical pipeline
Application scenario: Chemical medium transmission pipelines in refineries and chemical plants (such as acid, alkali, salt solutions).
Advantage:
The material can be 316L stainless steel or corrosion-resistant alloy, and the inner wall is polished to Ra0.2 μ m to prevent residual media and bacterial growth.
Complies with ASME BPE standards and meets food grade and pharmaceutical grade hygiene requirements.
Nuclear power equipment pipeline
Application scenarios: nuclear reactor cooling systems, auxiliary equipment pipelines.
Advantages: High precision processing ensures sealing, prevents radioactive material leakage, and can withstand high temperature and high pressure environments.
Oil and gas extraction pipeline
Application scenarios: drilling platforms, downhole tools (such as drill pipes, casing).
Advantages: Smooth inner wall reduces drilling fluid resistance, improves drilling efficiency, and reduces the risk of stuck drilling.
