The hydraulic tube is mainly designed to deliver hydraulic fluid between hydraulic components, valves, actuators, and tools. It is very flexible because the hydraulic system is often operated under high or ultra-high pressure. Thus, its structure is usually reinforced by several layers of reinforcement. 

Whenever you are going to purchase these tubes, then you have to get them from dependable hydraulic tube suppliers. There are diverse suppliers present across the globe. However, all of them do not provide top quality tubes. You need to pick the one that has a good reputation in the market.

How to select the inner diameter of the hydraulic tube?

Hydraulic pipes are widely used in various industrial hydraulic systems. Size, performance specifications, materials, and functions are all critical parameters to consider when selecting the inner diameter of the hydraulic tube.

Structure

Like most industrial pipes, hydraulic pipes consist of three basic parts: the inner tube, the reinforcement layer, and the outer cladding. Plastic or rubber tube or liner, which makes contact with the fluid. A fiber, plastic, or metal body or carcass that strengthens the structure of the pipe. In this way, it is able to withstand internal and external pressure. Reinforcement is the key to hydraulic pipes because it ensures that the pipes can withstand the high pressures involved. Types of reinforcement include wire braiding and wire winding.

Steel wire braid reinforcement (marked as W in the parameter table) usually provides more flexibility. However, it is more prone to failure in high-pulse applications. Wire winding reinforcement (marked S in the parameter table) usually provides higher strength. Nevertheless, it is affected by increased stiffness and a minimum bending radius. Some new winding pipe technologies have overcome the problem of rigidity. The coverings of rubber, plastic, metal, or textile can prevent damage. There are many different pipe designs based on weave type or weave structure and material layers.

Inner Dimensions

Size is the most basic and most important factor in the selection of the inner diameter of the hydraulic tube. Hydraulic pipe size specifications include inner diameter, outer diameter, and length. The inner diameter (ID) is the span of space in the cross-section of a circular pipe that affects the flow rate of fluid in the pipe.

The pipe has a system performance that is too large for the internal diameter to be late. A narrow internal diameter can cause excessive pressure drop, leakage, and system damage. You have to know your requirements before choosing the inner diameter of the hydraulic pipe. In this manner, you will be able to get the best tube from the hydraulic tubing suppliers.

Performance parameter

The essential performance parameters of hydraulic pipes include rated temperature and pressure level. Hydraulic pipes often work at temperatures of a few hundred degrees Celsius, and in applications where the rated temperature exceeds the temperature limit. These limits include medium temperature (temperature of hydraulic fluid) and ambient temperature (temperature of the surrounding environment). Operating pipes above or below the rated temperature range can reduce their service life and adversely affect their performance (e.g., loss of elasticity, cracking). Based on the thermal stability and thermal capacity of the fluid, the type of hydraulic fluid delivery can also increase or decrease the effect of temperature changes on the pipe. Because of this, some manufacturers specify different temperature grades for various fluids.
