What is spiral hydraulic hoses
A spiral hydraulic hose, or spiral hose, is a high-pressure hydraulic hose that is a critical part of hydraulic systems used in dozens of industries. Spiral hoses get their name from their reinforcement, which is made of multiple layers of steel wire (usually four or six layers) that are twisted together and stacked in alternating directions to create a "spiral" shape. Of the two main types of rubber hydraulic hoses (braided or spiral), spiral hydraulic hoses are the preferred choice for high-pressure applications and extreme conditions, and the added rigidity of their spiral construction makes them stronger and safer than the more flexible braided hydraulic hoses. However, due to this rigidity, the bend radius of spiral hoses is significantly smaller than that of braided hoses. As with all things, which type of hose to choose depends on the application.
Where can Spiral Hydraulic Hose used?
Spiral hoses are reliable and rugged high-pressure hydraulic hoses that can get heavy-duty jobs done safely and efficiently. They are popular in industries such as construction, mining, agriculture, highway maintenance, and any application that needs to handle high peak pressures and rigorous operating conditions. Spiral hydraulic hoses are versatile and highly sought after. As a result, there are many different categories, types, and sizes of spiral hoses, so finding the right hose and size for your operation can be difficult and overwhelming.
Difference between Spiral and Braided Hydraulic Hoses?
Construction
For braided hoses, as the name implies, this layer consists of steel wires that alternately cross to form a braid. The manufacturing process is fairly complex and requires the use of large braiding machines to form the braid on an extruded inner tube. It also requires an extensive quality inspection protocol to ensure that the braid does not split; otherwise, the thickness of the final product will be affected.
Spiral hoses, on the other hand, also have steel wires wrapped around the inner tube, but instead of interlacing, they are arranged in parallel in a spiral pattern. Manufacturing a spiral hydraulic hose is generally faster than a braided hose because it has the same number of reinforcement layers.
Flexibility
Braided hoses are more flexible than spiral hoses. This is because the interlocking pattern of the braid gives it a higher tensile strength. Spiral hydraulic hoses require additional layers of counter-helix to withstand the same pressure as braided hydraulic hoses, which increases its outer diameter and reduces its minimum bend radius. Therefore, braided hydraulic hoses are ideal for applications that require the hose to be twisted in an unconventional position to be installed.
Durability
Durability is one area where spiral hoses outperform braided hoses. In hydraulic systems where pressure changes occur frequently, the hoses tend to expand and contract to compensate for the peaks and drops in pressure. Over time, these changes can cause braided hoses to lose tensile strength as the tightness between them weakens. Additionally, the friction between the braided wires generates heat, which degrades the performance of the inner and outer tubes. Spiral braids tend to exhibit higher resistance to pressure changes, making them more durable in the long run.
Applications
Most braided hoses are suitable for low- to medium-pressure applications, such as return lines, hydraulic lifts, and large engines. Spiral hoses are ideal for hydrostatic drives that operate at higher pressures and have rapid pressure changes. They are most commonly used in large, specialized heavy machinery, such as mining excavators and off-road dump trucks.
