Types of hydraulic oil pipes Hydraulic oil pipes are divided into high-pressure steel wire braided hydraulic oil pipes and cloth-covered rubber hydraulic oil pipes according to their materials. Among them, steel wire braided hydraulic oil pipes are the most widely used. They have high strength and toughness, can withstand high pressure and impact loads, and have good thermal conductivity. They are suitable for high temperature and high pressure environments.
High-pressure bearing capacity: Hydraulic oil pipes have high strength and high pressure-bearing capacity, and can meet the working requirements in various high-pressure environments.Wear resistance: The surface of the hydraulic oil pipe has been specially treated to have excellent wear resistance and extend its service life.High temperature resistance: Hydraulic oil pipes can work normally in higher temperature environments and adapt to various harsh working conditions.Good sealing performance: The hydraulic oil pipe has excellent sealing performance and can effectively prevent leakage.Easy to install and maintain: Hydraulic oil pipes are easy to install and have low maintenance costs, providing convenience for production.| Speci -cation | Grade | Chemical Composition [%] | ||||||||||||||
