The pressure level of high-pressure hydraulic oil pipes is determined by factors such as their wall thickness and material. At present, the pressure Elo rating system of high-pressure hydraulic oil pipes are generally divided into the following five grades:
Low pressure: The working pressure of low-pressure hydraulic oil pipes is usually below 6.3MPa. This type of hydraulic oil pipe is mainly used in mild industrial environments, such as automotive manufacturing, mechanical manufacturing, aerospace, etc.
Medium pressure: The working pressure of medium pressure hydraulic oil pipes is usually between 6.3MPa and 31.5MPa. This type of hydraulic oil pipe is mainly used in some complex and strict industrial environments, such as metallurgy, mining, steel, etc.
High pressure: The working pressure of high-pressure hydraulic oil pipes is usually between 31.5MPa and 50MPa. This type of hydraulic oil pipe is mainly used in some special industrial environments, such as nuclear power plants, aviation, marine, etc.
Ultra high pressure: The working pressure of ultra-high pressure hydraulic oil pipes is usually between 50MPa and 100MPa. This type of hydraulic oil pipe is mainly used in some special high-pressure environments, such as high-speed trains, spacecraft, etc.
Ultra ultrahigh pressure: the working pressure of ultra ultrahigh pressure hydraulic tubing is usually above 100MPa. This type of hydraulic tubing is mainly used in extremely special industrial environments, such as Nuclear fusion reactors, ultra-high pressure water jets, etc.
