Product advantages

• The use of high-strength materials and special heat treatment and welding processes ensure that the cylinder has a very high fatigue life under high pressure and heavy load

• Part of the cylinders are specifically designed to meet high vibration conditions during TBM construction

• Design a reliable sealing configuration suitable for TBM working conditions for different types of cylinders

• Can be designed and integrated hydraulic locks, balance valves, etc. according to requirements

• The design has a wide temperature range (-20℃~+80℃), and can provide higher or lower temperature cylinder customization services

• The theoretical analysis and finite element calculation of the system can make the design of the cylinder structure more optimized and safer

• Working pressure, size specifications, installation methods, etc. can be customized according to customer needs
