Minimum bending radius of high pressure hose

High pressure rubber hoses are widely used in mine hydraulic equipment, coal industry, petroleum industry, agricultural machinery, other various machines, various hydraulic systems and engineering and construction industries to transport petroleum-based or water-based liquids with high pressure temperature and high pressure. The characteristics of high pressure and temperature resistance, oil resistance, corrosion resistance, aging resistance and weather resistance make it well used in the application scenarios mentioned above.

Proper installation is a prerequisite for the high pressure rubber hose to work well, and the minimum bend radius of the high pressure rubber hose is an indispensable part of the correct installation process. Let's start from three questions and talk about the minimum bending radius of high pressure rubber hoses:

Q1 What is the minimum bending radius of the high pressure rubber hose?

The minimum bending radius of the high pressure rubber hose refers to the minimum value of the bending radius the high pressure rubber hose will not be damaged and can work well.

Q2 What affects the minimum bend radius of the high pressure hose?

Reinforcement layer production process:

The high pressure rubber hose is composed of three layers: inner rubber layer, reinforcement layer and outer rubber layer. The reinforcement layer is generally made of high-strength steel wire through braiding or spiraling process. For the steel wire braided hose, it is more flexible, so the bending radius is smaller; while the reinforcement layer made of the steel wire spiral process has higher strength and is less easy to bend.

Number of reinforcement layers:

For the high pressure rubber hose made by the steel wire braiding process, the more braided layers, the smaller the minimum bending radius of the high pressure rubber hose; for the high pressure rubber hoses made by the spiral process, the six-layer steel wire spiraled rubber hose must be stronger than the four-layer steel wire spiraled rubber hose, and the bend radius is larger.

Material of high pressure hose:

Using a more rigid material for the high pressure rubber hose will make the high pressure hose stronger and have a larger bend radius.

Q3 How to utilize the minimum bending radius of the high pressure hose？

The bending radius is one of the factors that you need to consider carefully during the installation process. Correct use of the bending radius can avoid damage to the high pressure rubber hose: If the bending radius of the high pressure rubber hose is smaller than the minimum bending radius, firstly, the rubber hose will be in a fatigued state during the working process, and failures may occur. Secondly, the smaller bending radius will also cause the unsmooth delivery of liquid, and it will also lead to local high temperature, which will increase friction locally and lead to rupture. In addition, cracks may occur at the bend area, accelerating the aging or damage of the high pressure rubber hose. Therefore, the correct use of the minimum bend radius of the high pressure rubber hose is critical.

If it is damaged due to excessive bending, it can only be replaced in time. We recommend proper use within the specified range according to the manufacturer's model requirements. If you choose our high pressure rubber hose, we will be happy to patiently solve your problem.
