Hydraulic Pipes, Tubes, and Hoses

- Mar 08, 2018 -

 

It is important to distinguish what type of hydraulic equipment is being connected in the system to determine what fittings are appropriate.

 

  • Hydraulic tubes are seamless precision pipes specially manufactured for hydraulics. The tubes have standard sizes for different pressure ranges, with standard diameters up to 100 mm. Tubes lengths are interconnected via flanges, welding nipples, flare connections, or by cut-rings. Direct joining of tubes by welding is not acceptable since the interior cannot be inspected.

  • Hydraulic pipes are larger diameter hydraulic tubes. Generally these are used for low pressure applications or when hydraulic tubes are not available. They can be connected by welds or threaded connections. Because of the larger diameters the pipe can usually be inspected internally after welding.

  • Hydraulic hose is graded by pressure, temperature, and fluid compatibility. Hoses are used in applications where pipes or tubes are not suitable, usually to provide flexibility for machine operation or maintenance. The hose consists of multiple layers of rubber and steel wire. Hydraulic hoses generally have steel fittings swaged on the ends. The weakest part of hydraulic hose is the connection of the hose to the fitting, which is why proper fitting selection and installation is essential in high pressure applications.
