Hoses play a crucial role in several industries in carrying fluids, gases, and other materials. However, choosing the right hose is not as easy as it sounds. A wrongly chosen hose not only leads to leaks but also causes financial losses. That’s where the STAMPED hose identification method comes into the scene.
STAMPED is a reliable and straightforward way to identify, select, and specify a perfect hose for a particular job. It not only removes the confusion but also ensures that the hose performs efficiently in its environment. Are you new to the STAMPED method concept? Worry not! In this article, I will clarify everything about this method and help you understand it. So let’s get started!
What is the STAMPED Method?
Let’s first understand the basics of the STAPMED method.
STAMPED is a standardized system that is used to identify and select the right hose for the right job. It is the acronym of seven letters. Those include Size, Temperature, Application, Material (or Media), Pressure, Ends, and Delivery. Each of these letters provides valuable information about the hose’s design and its working condition.
In simple words, the STAMPED method is like a checklist. It provides users with a complete guide to what to look for in a hose for a specific job. For example, it specifies the size, pressure capacity, and temperature resistance a hose should have. As a result, this method prevents guesswork, which can cause leaks, accidents, and hose failure.
Why is the STAMPED Method so Valuable?
Now you understand the basic know-how of the STAPMED method. Right? Let’s discuss why this method is highly valuable in industries.
- Simplifies Selection Process. The main perk of this method is its simplicity. As you know, there are several sizes, materials, and types of hoses. So it becomes confusing to choose the right one. But the STAMPED method provides seven simple steps to identify the right hose for your needs. It eliminates guesswork and provides a direct path to the right hose.
- Saves Money & Time: When you choose the wrong hose, it leads to frequent replacement. This not only wastes your time but also your money. However, the STAMPED method prevents incorrect selection by providing the proper guidance. When you invest wisely in the hose, it pays off in the long term.
- Improves Safety: The STAMPED method ensures hose safety. It helps you choose the hose for the suitable fluid. As a result, the risk of damage and leakage is reduced, and fluid is transferred safely without accidents.
- Improves Efficiency: When you choose the wrong hose, the chances of damage increase. Right? This damage can ultimately affect the entire system’s efficiency. Even in some cases, it can stop the whole system. However, the STAPMED method helps you choose the hose that best handles fluids. This improves the system’s performance and overall reliability.
STAMPED Hose Identification Method
As I said above, each letter in the STAMPED method identifies unique specifications. So let’s discuss what each letter means and how it helps you choose the hose that best suits your needs.
S = Size
The first letter of the STAMPED method concerns choosing the correct hose size. In size, there are three parameters. Those include the Inside Diameter (I.D.), the Outside Diameter (O.D.), and the overall length. The inside diameter is about the thickness of the hose and determines the fluid’s flow capacity. How?
If the inside diameter is too small, it can restrict fluid flow and increase fluid pressure. As a result, the risk of hose rupture increases. On the flip side, if it is too large, the fluid’s pressure decreases, and it becomes unstable. Now, the outside diameter (O.D.) affects hose placement, especially in tight spaces.
So you should choose the right diameters based on the available space. Lastly, the entire length of the hose also matters. It includes measuring the hose’s length from tip to tail. A hose that is too short or too long can affect its handling. So you should measure the correct length of the hose needed for your project. The hose manufacturer can design it to that length, which prevents you from the hassle.
T = Temperature
The second and most important factor in the STAMPED method is to identify temperature. Here, you should understand two types of temperature ranges. The first is the temperature of the fluid flowing through the hose. If the fluid temperature is too high, it can cause the hose to rupture and melt. However, the lower temperature can make the hose stiff.
The second temperature is the environmental temperature in which the hose will operate. This temperature also affects the hose’s durability. For example, if you use the hose in extremely hot temperatures, its outer surface will deteriorate. On the flip side, freezing temperatures can cause hose stiffness. Therefore, you must choose the hose material specified for the required temperature range.
A = Application
The third step to buy the hose is understanding its application. In other words, you will have to determine where it will be used. Remember, every hose is designed for a specific job. A single hose cannot handle every type of job. So first, you should understand which job you are buying the hose for. For example, a hydraulic hose must handle high pressure.
However, a food-grade hose must be non-toxic and resistant to bacteria. Similarly, if you are buying a hose for fuel, it must be fire- and chemical-resistant. Like this, an air hose must be lightweight and flexible. In this way, you should first understand the nature of your project. After that, choose the hose that fits it perfectly.
In addition to the application, consider the environmental conditions where the hose will be used. For example, you should evaluate whether it will be used indoors or outdoors, or in moisture-prone environments. This factor will also help you choose the right hose for a specific application.
M = Media
The next factor you must consider when choosing a hose is the media. It refers to the material that will pass through the hose. There are various types of media. Some of those include air, water, fuel, chemicals, gas, and food products. You should know that not every hose can handle every type of material equally. Every media reacts differently to the hose components.
For example, the hose designed to handle air differs in composition from the hose designed to hold fuel. If you choose the wrong hose material for the media, it will deteriorate the hose’s structure. To prevent this, you should understand the nature of the media and then match it to the hose’s material.
For example, rubber hoses are usually used for air handling. However, PTFE (Teflon) hoses are ideal for strong chemicals and oils. On the flip side, PVC hoses work well for light-duty fluids or food products. Lastly, identify the media’s state. For example, whether your media is in a liquid, gas, or solid state.
P = Pressure
Now, it’s time to identify the pressure range of your hose. It actually refers to the maximum force a hose must withstand when carrying the media. If the media exerts too much pressure on the hose, it will cause bursts and leaks. You will find two types of pressure ratings on the hose. The first one is working pressure.
It is the maximum pressure the hose can safely handle during its operation. The second one is burst pressure. It is the point at which the hose can no longer withstand the pressure and breaks. So when you buy a hose, you must check that the burst pressure is always higher than its working pressure. This is called a safety factor, which allows the hose to operate safely under high pressure.
Besides media pressure, you should also consider surges and spikes in pressure, especially for the hydraulic hose. It is the pressure that a hose faces when starting or shutting off. If the hose is not strong enough to withstand these pressures, it will burst.
E = Ends (End Fittings)
The STAMPED method also helps us identify the right types of ends or fittings. These are the connection points at the ends of the hose that allow it to connect to the equipment or hose. In simple terms, fittings ensure a leak-free transfer of media from one place to another. The STAMPED method suggests that when buying a hose fitting, you should understand its three factors.
Those include the fitting’s material, size, and type. Common types of fittings include threaded, flanged, quick-connect, and cam-lock. However, the fitting is available in brass, stainless steel, carbon steel, or aluminum. When selecting fitting material, ensure it is compatible with the media flowing through the hose. Why?
Incompatible fittings will rust when they come into contact with media such as acids, fuels, or chemicals. For example, stainless steel fittings are ideal for chemicals. Why? Because they resist rust and chemical reactions. In the end, you should choose the right size of the fitting to ensure a secure connection and prevent leaks.
D = Delivery
The last step in the STAMPED method describes the delivery method for your hose. It helps you decide the final details of how the hose should be supplied or delivered to you. Delivery first includes shipping details. For example, how your hose should be packed (custom or labeling). You can also decide whether the hose should be coiled, straight, or on a reel.
Secondly, in delivery, it includes instructions for everything before the hose reaches you. For example, you can decide whether fittings should be attached at each end. Moreover, you can tell the hose supplier whether the hose should be pre-assembled or sent loose.
Conclusion
Hoses have become the most critical part of almost every industry. They safely transfer materials from one place to another and also help run several machines. However, when it comes to choosing the hose for the right job, many people get confused. That’s where the STAMPED method comes in. In this article, I discuss how the STAMPED method helps you choose a hose.
It stands for seven factors. These seven factors are what you should keep in mind when buying a hose. For example, you should understand size, temperature, application, media, pressure, ends, and delivery. In simple terms, STAMPED is the method that prevents hassles like leaks, issues, bursts, or failures later.
