Hydraulic hoses are essential components of many industrial systems, powering some of the most demanding equipment in the world. But what type of raw materials are used to make them? This post will explore four universal rubbers and their characteristics to help you determine what your hydraulic hose is made of. In general, metal fittings are used in most hydraulic systems due to their high nominal pressures. Plastics, on the other hand, have greater resistance to corrosion than metals, but they have lower strength and durability, making them less suitable for hydraulic systems.
The operating environment in which the hose will be used will also help you narrow down your search for the right material. Some places and conditions, such as temperature or exposure to aggressive chemical elements, can cause even the most delicate materials to degrade and decay over time, resulting in a less efficient hose, higher replacement costs and a greater potential for damage to the entire hydraulic system. When creating a quote for the repair of a telescopic hydraulic cylinder, you will receive four price ranges. Other factors that can affect the usability and durability of hydraulic hoses are the radius of curvature (the amount of curvature the hose has and the way it can bend a corner) and any temperature requirements or restrictions that your application has.
Mid-RangeThis range is for a hydraulic pump or hydraulic motor that has visible shaft wear or that may have a performance problem.
Typical Price RangeThis is a wide range that will give you an idea of what a typical hydraulic hose repair will cost without knowing the actual types of hose ends found on your hose assembly.
Low RangeThis range is for a hydraulic pump or hydraulic motor that works well, has no visible wear and only leaks.
Types of Rubber Used in Hydraulic HosesWhen it comes to selecting the right material for your hydraulic hoses, there are four main types of rubber that are commonly used. Each type has its own unique characteristics that make it suitable for certain applications.
Let's take a look at each one in more detail.
Neopreneis often used as the main or auxiliary rubber in the external structure of hydraulic hoses. It is highly versatile and can flex as needed without compromising its integrity or longevity. Neoprene is also resistant to oil, ozone, and weathering, making it an ideal choice for outdoor applications. Natural rubber is often used in the outer layer of hydraulic hose structures, although it is occasionally supplemented with other rubber materials to improve overall performance.
Natural rubber is highly resistant to abrasion and offers excellent flexibility and durability.
Nitrile rubber, also known as Buna-N or NBR, is commonly used in industrial applications due to its excellent resistance to oil and fuel. It also offers good resistance to abrasion and weathering.
Silicone rubberis often used in high-temperature applications due to its excellent heat resistance. It also offers good flexibility and resistance to abrasion.
Choosing the Right Hydraulic HoseChoosing a hydraulic hose isn't that complicated once you've started to understand the different options and why they exist.
A wide network of industries depends on hydraulic energy and, for each application, there is a suitable hydraulic hose to optimize the performance of hydraulic systems in each of these diverse scenarios. The raw material for hydraulic fittings must have adequate strength and corrosion resistance to safely handle the high pressures characteristic of hydraulic systems. When selecting a material for your hydraulic hoses, it's important to consider factors such as temperature requirements, exposure to aggressive chemicals, radius of curvature (the amount of curvature the hose has and how it can bend around corners), and any other environmental factors that could affect its performance over time. With this information in hand, you'll be able to make an informed decision about which type of rubber is best suited for your application.
