Many mechanical equipment on offshore drilling platforms is driven by hydraulic pressure, among which various hydraulic cylinders play a pivotal role.
Hengli hydraulic cylinders designed for harsh offshore environments can meet the demanding requirements of offshore drilling platforms in terms of safety, anti-corrosion performance and heavy-duty operations. Special structure design, using well-known seal brand to ensure excellent sealing performance. In view of the long-term low temperature environment, advanced welding methods are used, and the welding seam is inspected with a 3D stereo microscope with super depth of field, which fully meets the needs of various third-party inspection organization and customers.
We have a patented HengliExpoNite marine environment anticorrosive coating solution, which can provide customers with better and more suitable solutions according to the marine climate characteristics of different regions and the different areas of use of hydraulic cylinders.

Make the hydraulic cylinder coped with the working environment of high temperature, high humidity and high salt spray with better performance.
For example, a well-known domestic offshore oil equipment company selected Hengli's triple hydraulic cylinders for its offshore oil exploration drilling platform. And Hengli passed the final user's completion acceptance at one time, improving the efficiency and reliability of on-site construction significantly.
Whether it is deep sea operations, polar operations or other difficult and dangerous environments, Hengli has always maintained close cooperation and communication with customers and provide expert consultants. We constantly tried new technologies to ensure excellent product performance.
