Product Advantages
• The use of high-strength materials, 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 operation • Design a reliable sealing configuration suitable for TBM working conditions for different types of cylinders • It can be designed and integrated with P.O. check valves, counterbalance valves, etc. according to requirements • The design has a wide range of temperature resistance (-20℃~+80℃), and can provide higher or lower temperature cylinders • The theoretical analysis and FEA 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 the customer needs
