Polyurethane tube lining

Polyurethane-lined cylinders refer to the inner protective layer of industrial equipment made primarily from polyurethane elastomers. Their core function is to extend the service life of the equipment and ensure production stability through the material's wear-resistant, corrosion-resistant, and high elasticity properties.

Material Characteristics

Wear resistance
Polyurethane exhibits wear resistance 3-5 times that of natural rubber, particularly outstanding in environments below 80°C.
Case: In sand mills, the wear resistance of polyurethane lining can significantly reduce the wear on the cylinder from the grinding medium, thus lowering maintenance costs for the equipment.
Corrosion resistance
Polyurethane exhibits high resistance to non-polar mineral oils, fuel oils, and mechanical oils, effectively preventing medium corrosion of the lining.
Application: In chemical pipeline systems, polyurethane lining effectively transports acidic and alkaline media, reducing the risk of pipeline leakage.
High elasticity and recovery resilience
Polyurethane elastomers offer a wide hardness range (Shore A10-D95), combining the flexibility of rubber with the high strength of plastic.
Advantages: Absorbs vibration energy, reduces impact damage to the cylinder, and improves equipment stability.
High purity, pollution-free
Polyurethane-lined abrasive particles can be completely eliminated through heat treatment, preventing contamination of materials. Particularly suitable for industries that require high purity, such as food and pharmaceuticals.
High surface gloss
Polyurethane lining features a smooth surface, which prevents material adhesion, enhancing grinding efficiency and reducing residue.
 

Technical Advantages

Noise Reduction Performance
Polyurethane lining can effectively reduce noise during equipment operation, improve the working environment, and decrease noise pollution.
Damping performance
Polyurethane lining offers excellent vibration absorption properties, reducing equipment vibration and enhancing operational stability.
Radiation Resistance
Polyurethane lining maintains satisfactory performance under radiation doses of 10⁶-10⁸ Gy, suitable for special operating conditions.
