How Does Temperature Affect High-Pressure Hose Assemblies?

As you already know, hydraulic hose assemblies are under a lot of pressure. No matter what temperature they’re operating under, it’s important that it doesn’t affect their performance or safety. Choosing the right hydraulic hose assembly for your apparatus is important. Here’s a guide to choosing appropriate hose assemblies when it comes to temperatures experienced in the working environment.

How does temperature affect hoses?

First of all, determine whether your hoses have a rubber interior. Rubber is notorious for changing properties depending on heat. If you have to use your hoses during extreme heat, consider operating them at a lower temperature. Most materials expand and contract with heat, let alone pressure. This can determine whether they’re suitable for a certain application.

Your hoses need to be able to withstand internal and external temperatures. That is, can your hoses withstand hot (or cold) high pressure gas, liquid or other contents in the general ambient temperature?

As you know, this usually depends on material. Stainless steel hoses are much more likely to withstand extreme temperatures than plastic or PVC, which cracks and strains in extreme weather.

Temperature and hoses

Here are some ways temperature might affect hydraulic hose assembly:

• Maximum intermittent ambient temperature: This construction uses a rubber inner tub or cover. It can have a major change in properties when exposed to extreme weather, so consider the hose rating when choosing this type.
• Fluid temperature: Your fluid temperature makes a difference in what kind of hose you should choose. If you’re not sure, ask one of the team members at Royal Brass, Inc.
• Ambient temperature: This is the environment where you’re going to use the hoses. If it’s indoors, for example, it won’t have the same temperature as it would if you were working outdoors in the San Jose summer.
• Maximum temperature: Next, consider the maximum temperature that the fluid and your environment could reach. Think about the highest possible temperature it could reach under extreme operating conditions. Then, select a hose that can handle those temperatures.
• Minimum temperature: This is the lowest temperature that your hose and fittings will be exposed to. If you’re in San Jose, you know that this is usually somewhere between 25 to 35 degrees Fahrenheit environmentally. If it’s lower for the liquid, take that into account as well.

These factors will all determine which hydraulic hose assemblies you choose. As always, your specific industry, practices and business type will determine which type of hydraulic hose assemblies is the right option for you.
