Hoses, pipes, and tubes are often necessary in many applications. Hoses are flexible, like rubber, plastic, or stainless hoses. Pipes are rigid, and tubes are almost similar to pipes but made of thinner walls. All of these can transport liquids and gases. However, the suitability depends on your project needs.
Does your project involve movement? How about the sizes? Stability, durability, and strength play crucial roles in this case. A stable hose prevents leaks and reduces project downtime. Durable hoses always ensure lower operating and maintenance costs. On the other hand, strength ensures that your hoses are stable even under high pressure and temperatures.
Stainless hoses outperform rubber hoses in many situations. In short, they resist high pressure, corrosion, and heat. Unlike rubber, stainless steel hoses do not crack, warp, or form dry rot over time. In this article, you will be familiar with all of these and learn why stainless hoses can replace many rubber hoses.
What are stainless hoses?
Stainless steel hoses are typically made of stainless steel. Some may come with SS braiding and a rubber or plastic inner tube. However, they typically have two main forms: corrugated and braided. Both offer excellent flexibility and strength. These hoses can be used for systems that need strength, durability, and corrosion resistance.
Stainless hoses’ main job is to transfer fluids or gases, the same as other types of hoses. What makes them different is the environment in which they are used. Stainless hoses are highly suitable for use in high-temperature or high-pressure environments. Due to their robust construction, these hoses are durable and highly reliable.
Benefits of using stainless hoses
Stainless hoses offer numerous benefits, making them great alternatives to rubber hoses. Let’s check them out!
(1) Stainless hoses are long-lasting. They can endure many environmental factors, such as wear and tear and friction. Therefore, you don’t have to worry about replacing the hoses frequently.
(2) Stainless steel hoses are also highly temperature resistant. The presence of chromium in their chemical structure typically produces a chromium oxide layer, which is responsible for SS’s corrosion resistance. Because of this, stainless hoses are ideal for transporting corrosive materials.
(3) One of the advantages of using stainless steel hoses is their resistance to temperature and pressure. Stainless steel hoses can endure high pressure and temperature and maintain your hose’s integrity.
(4) Despite their strength, SS flex hoses are also flexible. You can install them in tight spaces. However, you must choose between different flexible hose types. This versatility typically makes stainless hoses an ideal option for complex setups.
(5) Stainless steel hoses need less maintenance. Once installed, you don’t have to worry about cleaning or maintaining them, and as a result, stainless steel hoses are durable.
(6) SS flex hoses are safe, and food-grade materials are available. They may often be used in pharmaceuticals and water treatment facilities.
Types of stainless hoses
As you know, stainless steel is a rigid material. When you make pipes and hoses, they are also rigid. Working with rigid pipes or hoses is sometimes inconvenient, though rigid hoses have many benefits. To solve the inconvenience, engineers devised a few solutions. The following two types are two of the most popular ones.
SS Corrugated Hose
SS corrugated hoses are among the most popular flexible metal hoses. As the name implies, these stainless hoses are made in a corrugated form. This particular corrugated structure typically absorbs vibrations and compensates for thermal expansion.
SS corrugated hoses are widely used in high-temperature systems. You can use it to transport steam and hot water. You will find that many industrial machinery uses these stainless hoses for connections.
SS Braided Hose
So far, these stainless hoses are the most popular in industrial and commercial applications. As the name implies, they have a braided reinforcement layer in the construction. The braided structure means the reinforcement material is in interlocking designs. This special structure typically improves the strength of the hose.
SS braided hoses can endure more mechanical stress, making them very strong. As a result, these hoses make your system more stable. Also, they prevent external damage.
SS braided hoses are widely used in hydraulic systems. You may also find its use in gas transportation works. Moreover, fuel and oil machinery also use these hoses a lot.
Why Should You Replace Rubber Hoses with Stainless Hoses?
We use rubber hoses in various applications, from pure rubber to reinforced rubber. Although they are popular in many applications, they also have some problems. That’s where the other types of hoses shine.
SS flex hoses are often a better alternative. They are excellent against corrosion and durable. They are also safer because they don’t kink or leak. The following four points are the primary reasons for replacing rubber hoses with stainless ones.
Reason #1 Last Longer
Rubber hoses do, indeed, wear out over time. They are likely to crack, harden, and break down. Some rubbers, like EPDM, can withstand weather, while others might be good against chemicals. The main things that damage rubber hoses are usually sunshine, chemicals, and pressure.
In this case, stainless hoses are a great alternative to rubber hoses. They offer great longevity, which may not be possible with other types of hoses. A stainless-steel hose is excellent against corrosion, chemicals, and UV. Its body can also withstand and maintain high strength even after years of use. Although the initial cost is high, you can save replacement costs in the long run.
Reason #2 Safer
Rubber hoses are also safe but have a shorter lifespan than stainless steel ones. Safety is a big issue in the auto, chemical, and food handling industries. If your rubber hose wears out or you haven’t replaced it promptly, it is dangerous to work with it. It can fail anytime, leading to leaks, spills, or dangerous accidents.
Stainless hoses are much safer. They are less likely to rupture or leak under stress. As you already know, SS316 has a tensile strength of 579 MPa or 84 KSI. Also, stainless steel products offer great strength, which reduces the risk of accidents. So, you can replace rubber hoses for critical applications. You can protect workers, equipment, and the environment from hazards.
Reason #3 Don’t Bend
Because rubber tubes are bendable, they can be used for many different things. But being flexible can be a problem sometimes, like when they bend or kink. Kinking is a big problem. It stops the flow of liquids or gases when it happens. Most of the time, this situation increases the pressure there. If your hose continues to do so, it may leak or even burst sometimes.
You don’t have to worry about bending or kinking regarding stainless hoses. If you need flexibility, you have two options: corrugated and stainless braided hose. They both offer good flexibility along with strength and durability.
Reason #4 Pressure and Temperature Resistance
Another great advantage of stainless hoses is their performance. As you already know, metals offer high strength and melting points. Therefore, they can endure high heat and pressure.
Rubber hoses are also used for many high-heat and temperature jobs, though. However, the pressure rating is set and can only be used on certain types. Reinforcement layers are needed to maintain a high-pressure grade.
