We know there are many kinds of hydraulic hose for different work conditions. Some are for normal use, but some are for high pressure use. Then is there any difference between them?
The main difference between a standard hose and a high pressure hose is their max work pressure rating. Standard hose can handle relatively low to moderate pressure levels, up to around 3000 psi. High pressure hydraulic hose, on the other hand, is to handle much higher pressure levels. While the typical range is from 5000 psi to as high as 10 000 psi or more.
To achieve the higher pressure rating, high pressure hose has a reinforced structure. While the reinforce is multiple layers of steel wire or textile braid to provide additional strength and durability. The inner tube of a high pressure hose is often a more wear resistant material, such as NBR or Teflon.
In addition to pressure, high pressure hose is more flexible than standard hose. While this allow it to bend and flex more easily without kink or collapse. This can be important in the apps with a limit space or where the hose needs to move and flex as part of its operation.
You’d better use the correct type of hydraulic hose for the specific app. In addition, ensure that the hose is suitable to handle the max pressure levels. Using a standard hose in a high pressure app can lead to hose failure. What’s more, it may cause serious safe problem.
