How to Choose the Right Size Hydraulic Hose for Optimal Performance

Choosing the right size hydraulic hose is essential for ensuring optimal performance and durability of your system. To know the size of the hose, you should check the assembly line or measure the inner diameter of the original hose if it has worn out. Be sure to measure the total length of the assembly and the orientation of the connection before cutting the hose. A hydraulic hose is a flexible, reinforced rubber or thermoplastic duct that is used to transport fluid within a hydraulic or process system.

These hoses are usually reinforced with several layers of material to withstand the required pressure of the system in which they are used. One of the most fundamental considerations when selecting a hydraulic hose is its size. If it has an inner diameter that is too small, pressure losses may be high and excessive flow will generate heat, which can damage the inner tube of the hose and possibly cause an erosion of its flow. This can cause damage to joints, blockage of pumps, valves and filters, as well as failure of the hose itself.

On the other hand, if the inner diameter of the hose is too large, the volume of fluid contained will be greater than that needed for the operation of the equipment and routing it may be difficult. In addition, costs for assembling and connecting larger hoses may be higher than what is actually needed. Response time will also be delayed in hydraulic systems if hoses are too large. The size of a hose is determined based on its inner diameter (I.

D.). Hose sizes are designated based on their inner diameter, which is measured in inches even if assigned a metric size designation. The outer diameter (O. D.) can be used to ensure that it fits in its allocated space but has no direct impact on pressure loss and flow calculations within systems.

The size of a hydraulic hose must also take into account its maximum distance between two ends. As its length increases, frictional losses between fluid and its inner surface also increase, reducing pressure within the system. Therefore, you should consider its length when calculating pressure requirements for your system. If its inner diameter is slightly larger, pressure loss (also known as pressure drop) will be reduced.

The flow rate (expressed in gallons per minute or liters per minute) or speed (expressed in feet per second or meters per second) of fluid moving within your system is key to sizing your hose correctly. The maximum flow rate of your system is mainly determined from nominal values of pump used. Pump data can be found on pump manufacturer's label, in system specifications, or in pump manufacturer's catalog or website. This is sometimes expressed as “pump curves”, which are based on several variables including speed at which pump is operated.

Once you have established maximum flow rate for your system, use nomograph supplied in Jason Hose product catalog to easily determine appropriate selection for right size hose to obtain best performance and durability for given flow. Please note that as indicated in nomograph, hoses used for suction (pump intake) must be larger than those on pressure outlet side (pump outlet). To ensure best selection for their hose options, industry professionals adhere to S. T.

A. M. P. E.

D standards - System, Temperature, Medium, Pressure, Extremes and Delivery. The inner diameter of your hose must be correct size to ensure adequate fluid flow within your system. Excessive flow because it's too small or wrong internal diameter can cause inconsistencies, internal damage and liquid leaks while a hose that's too large can compromise system's response output. A wide variety of materials can be transported using hoses so you should consider possible physical or chemical reactivity between fluid medium and hose material.

If improper material is used in your hose or its accessories it can damage your system or cause it to fail and due to fault create hazardous conditions. Compressed gases require specially designed and manufactured hoses as some materials can damage reinforcement and even ends and joints all of which can result in sudden and catastrophic failure. Understand application and check compatibility if you have any questions or concerns. Your hydraulic hose will have to withstand working pressure of application as well as any additional pressure that may be due to fluctuations within system.

The specific application must be carefully considered to ensure that your hose is correctly selected for greater durability and safety when selecting ends or couplings consider size, material and application as accessories come in incredible variety of styles, orientations and attachment methods to meet particular needs of each system. Each type of connector has many attributes as well as limitations in terms of ratings and resistance to leaks and pressure. Timely and reliable delivery is need that's often overlooked when selecting right hose whether you need special packaging, one-time shipment, certification, testing or labeling Jason Industrial will help you get product you need when you need it. Accurate sizing requires combination of complex calculations and industry knowledge even if you have experience in field it's good idea to consult with manufacturing technician to get best tools for your project.

Selecting wrong hose for custom equipment can lead to system failures and unnecessary expenses but professional consultation can ensure best possible outcome.
