PRODUCT APPLICATIONS

1. Hydraulic and Pneumatic Cylinders: Due to their highly smooth inner surface and precision, honed tubes are ideal for
manufacturing hydraulic and pneumatic cylinders. These cylinders are used in various machines and vehicles for motion control.

2. Hydraulic Equipment: In various hydraulic systems, such as excavators, cranes, and hydraulic presses, honed tubes are used to construct key components of hydraulic equipment.

3. Automotive Industry: In the automotive industry, honed tubes can be used to make critical components like suspension systems and steering systems.

4. Heavy Machinery: Heavy machinery used in construction and mining industries, like bulldozers and loaders, often use honed tubes as one of their primary construction materials.

5. Precision Machinery Manufacturing: In precision machinery that requires accurate control and high reliability, honed tubes are widely used due to their precise dimensions and surface smoothness.

The inner and outer walls of the precision bright steel pipe are of high precision and high finish. After heat treatment, the steel pipe has no oxide layer, and the inner wall has high cleanliness. The steel pipe bears high pressure, does not deform during cold bending, and has no cracks during flaring and flattening. Therefore, the precision steel pipe can be processed for various complex deformation and machining.
