Hey there! As a supplier of PU steel wire hoses, I often get asked about the differences between PU steel wire hoses and rubber hoses. So, I thought I'd write this blog post to break it down for you.
Material Basics
Let's start with the materials. A rubber hose, well, it's made from rubber. Rubber has been around for ages and is a classic choice for hoses. It's flexible and can handle a fair amount of wear and tear. On the other hand, a PU (Polyurethane) steel wire hose is made from polyurethane, which is a type of polymer. The steel wire in it acts as a reinforcement, giving it extra strength.
Flexibility
When it comes to flexibility, both have their pros and cons. Rubber hoses are generally very flexible right out of the box. They can bend easily around corners and through tight spaces without much effort. You can pretty much twist them into all sorts of shapes. However, over time, especially in extreme temperatures, rubber can start to lose its flexibility. Cold weather can make it stiff, and hot weather can make it a bit too soft and prone to kinking.
PU steel wire hoses, though, maintain their flexibility better in different temperatures. The polyurethane material has a more consistent performance. It doesn't get as stiff in the cold or as soft in the heat. This means that no matter if it's freezing outside or sweltering, your PU steel wire hose will still be able to bend and move as you need it to.
Strength and Durability
Strength is a big factor when choosing a hose. Rubber hoses are tough, no doubt about it. They can withstand a good amount of pressure and abrasion. But they do have their limits. Sharp objects can puncture them, and over time, the rubber can start to crack and deteriorate, especially if it's exposed to chemicals or UV rays.
PU steel wire hoses, with their steel wire reinforcement, are much stronger. The steel wire gives them excellent resistance to pressure. They can handle higher pressures without bursting or deforming. And when it comes to abrasion, the polyurethane material is more resistant than rubber. It can take a beating from rough surfaces without getting damaged easily. Plus, PU is more resistant to chemicals and UV rays, so it has a longer lifespan in harsh environments.
Weight
Weight can be an important consideration, especially if you need to move the hose around a lot. Rubber hoses are usually heavier. The rubber material itself is dense, and depending on the thickness of the hose, it can add up. This can make it a bit of a hassle to carry around, especially for longer hoses.
PU steel wire hoses are generally lighter. The polyurethane material is less dense than rubber, and even with the steel wire reinforcement, they still weigh less. This makes them easier to handle, transport, and install. Whether you're using it in a small workshop or a large industrial setting, the lighter weight can save you a lot of effort.
Transparency
If you need to see what's flowing through the hose, transparency can be a crucial feature. Some rubber hoses are opaque, so you can't see inside. There are also clear rubber hoses available, but they tend to get cloudy over time due to oxidation and exposure to various substances.
PU steel wire hoses often come in clear versions, and they maintain their transparency much better. You can easily see the flow of liquids or gases inside, which is great for monitoring and troubleshooting. Whether you're checking for blockages or just want to see the quality of the fluid, the clear PU steel wire hose makes it easy.
Applications
The differences in properties also mean that they are suitable for different applications. Rubber hoses are commonly used in automotive, plumbing, and general household applications. They are a good all - around choice for low - to medium - pressure applications where flexibility is important and the environment is relatively mild.
PU steel wire hoses, on the other hand, are ideal for more demanding applications. They are widely used in industrial settings, such as in chemical processing plants, food and beverage industries, and high - pressure cleaning systems. For example, in the food and beverage industry, you can check out our Food Grade Steel Wire Hose, which is made of high - quality PU and meets all the necessary food safety standards.
In high - temperature environments, our High Temperature Resistant Steel Wire Hose is a great option. It can withstand extreme heat without losing its performance. And for applications that require high - strength and flexibility, our TPU Steel Wire Reinforced Hose is a top choice.
Cost
Cost is always a factor in any purchasing decision. Rubber hoses are generally cheaper upfront. They are mass - produced and have been around for a long time, so the manufacturing costs are relatively low. However, considering their shorter lifespan and potential for more frequent replacements, the long - term cost can add up.
PU steel wire hoses are more expensive initially. The cost of the polyurethane material and the steel wire reinforcement is higher. But when you factor in their longer lifespan, better performance, and lower maintenance requirements, they can actually be more cost - effective in the long run.
Conclusion
So, to sum it up, both PU steel wire hoses and rubber hoses have their own advantages. Rubber hoses are a good choice for basic, low - pressure applications where cost is a major concern and the environment is not too harsh. But if you need a hose that can handle high pressures, extreme temperatures, chemicals, and has a long lifespan, then a PU steel wire hose is the way to go.
