? 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.
? Design a reliable sealing configuration suitable for the working conditions of the shield machine for different types of oil cylinders
? 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
