Technical Terms to Consider in Hose Selection
There can be many technical details that cause confusion when choosing a hose. But don't worry, in this guide we will explain the terms of the hose world in the most understandable way. Diameter, pressure resistance, flexibility and more...
Once you know what these terms mean, choosing the right hose will be a piece of cake!
Diameter (Inside and Outside Diameter): Measure Determining the Capacity of the Hose
The most important factor determining the efficiency and speed of the fluid flowing through the hose is its diameter. Diameter has two main dimensions: inner diameter and outer diameter.
- The inside diameter determines the speed and volume of the liquid or gas flowing through the hose. For example, a hose with a large inner diameter allows for greater flow, making it ideal for high-volume processes. From garden hoses to industrial hoses, water pressure, flow rate or hose performance can be reduced if the diameter is not selected correctly.
- The outer diameter refers to the thickness of the hose and is related to its durability. In most cases, the thicker the outer diameter of the hose, the thicker the material and the more durable the hose becomes. The outside diameter is also important to consider depending on the connection points the hose will fit into. For example, if you don't pay attention to the OD when buying a hose to fit a narrow pipe, you may have connection problems.
Pressure Resistance: Force with which the hose withstands
- Pressure resistance refers to how long the hose can withstand pressure from the inside. There are two main pressure ratings: working pressure and burst pressure.
- Working pressure refers to the pressure level that the hose can safely withstand over a long period of time.
- Burst pressure is the highest pressure level that the hose can withstand; exceeding this value may cause damage or bursting of the hose.
- Understanding the difference between the two is crucial because in applications that require constant high pressure, system failures and safety issues can occur if you don't use a hose with the appropriate working pressure. For example, in an industrial cleaning hose, if you don't choose a hose that is resistant to high pressure, there is a risk of cracking or bursting. Therefore, buying a hose suitable for pressure is of great importance in terms of safety and efficiency.
Flexibility Ability of the Hose to Bend
- Flexibility is important for the easy handling of the hose in confined spaces and its functionality in applications where it needs to be bent. The flexibility of the hose usually depends on its material, thickness and diameter.
Flexible hoses provide comfort in tight spaces and are easy to install. However, flexibility can sometimes be inversely proportional to durability. Hoses that are too flexible can wear out more quickly if they are constantly kinked.
For example, if you are going to buy a hose that is constantly moving or installed in tight spaces, the flexibility should be high. However, it would be better not to choose a very flexible model for a hose that will remain stationary for a long time and work under pressure. Making this balanced choice directly affects the service life.
Temperature Resistance: Resistance of Hose to Fire and Cold
- The temperature range to which the hose can be exposed is another critical factor affecting its selection. Materials that can withstand different temperatures expand the range of uses for hoses. For example, some hoses remain flexible even at temperatures as low as -50°C, while others can withstand up to 200°C. For processes requiring high temperatures, silicone or glass fiber hoses are preferred. These hoses can continue to function at high temperatures without deforming. Flexibility is at the forefront in hoses to be used at low temperatures. Hoses that do not harden in cold weather offer a safer use by maintaining their flexibility.Hoses used in the wrong temperature conditions quickly wear out, lose flexibility and leak. Therefore, it is of great importance to choose a hose that is suitable for the temperature conditions of the environment in which you work.
Durability and Abrasion Resistance: Hose Resistance to Harsh Conditions
- Durability is the hose's resistance to external environmental influences. Especially hoses exposed to chemicals, abrasive surfaces and high friction must have high abrasion resistance.
For example, hoses used in chemical plants can be exposed to corrosive substances such as acids and oils. Chemical resistant hoses are specially manufactured for such situations. Likewise, physical abrasion resistance becomes important for hoses that rub against abrasive surfaces. The quality of the hose and the nature of the material used directly affect the durability.
Hoses with physical abrasion resistance offer long-lasting solutions, especially when used in harsh conditions such as quarries and mining. Evaluating the durability of your hose according to environmental conditions when choosing your hose will reduce future wear and costs.
Material Selection: Which Material is Suitable for Which Job?
- Hoses are usually made of different materials such as silicone, PVC and rubber, and each material has its own advantages.
Silicone hoses stand out with their resistance to high temperatures and flexible structure. It is preferred in the food and health sector due to its hygienic structure.
PVC hoses are frequently used in low pressure applications because they are economical and lightweight.
Rubber hoses, on the other hand, are highly successful in terms of flexibility and durability and are used in most industrial applications.
The choice of material directly affects the price, durability and range of use of the hose. Choosing the wrong material can result in a short-lived product. By paying attention to the material when choosing your hose, you can choose the most suitable product for your intended use.
Technical Terms Judge Becoming The Key to Conscious Shopping
Knowing these technical terms when choosing a hose allows you to make a more informed purchase. Choosing a hose with the wrong diameter, pressure resistance or flexibility can lead to system failures, safety issues and even extra costs. Choosing your hose correctly ensures long-lasting use and a safe working environment.
By getting information from hose experts, you can choose the most suitable hose for your work and make informed choices. Now that you know all the terms of the hose world, it will be much easier to find the hose that fits your needs!
