Alloy pipe

  Cylinder pipe are mainly applied in hydraulic driving equipment (including hydraulic and pneumatic steel cylinder, hydraulic support, oil-well pumping barrel, and etc.) used for the manufacturing of vehicle, engineering machinery, lifting and transportation machinery and other machinery. Liquid steel has high purity, excellent geometrical dimension and good performance for processing.
