During the operation of marine equipment, as the most important executive element, hydraulic cylinder is in the seaside for a long time. The water and salt content in the air is high, and the cylinder must have strong corrosion resistance. We adopt advanced composite electroplating process to ensure the superior corrosion resistance of the rod body in harsh environment.
Three-layer chromium composite electroplating process and sealing wax treatment are adopted for the rod outer circle , which guarantee the excellent corrosion resistance;
Compound sealing technology reduce the impact from oil pressure and enhance sealing performance;
Sheathed U butt welding technology has high welding performance and enhance the appearance.
