S.T.A.M.P.E.D. : The Seven Hose Assembly Specifications To Know When Determining The Appropriate Hoses for Your Application
If you are in the process of appropriately spec'ing a hose for your application, it is important to follow the industry standard process of S.T.A.M.P.E.D. The seven information points in the S.T.A.M.P.E.D. acronym stand for Size, Temperature, Application, Material, Pressure, Ends and Delivery.
In order to choose a cost-effective and safe hose assembly use the S.T.A.M.P.E.D. acronym to find the appropriate hose for your application. This acronym is an easy way to quickly provide the pertinent information to your hose supplier. Hoses used inappropriately, can cause serious injuries and lost production time which leads to expensive downtime.
The S.T.A.M.P.E.D Hose Selection Process
What are the inside and outside diameter size of the hose?
The industry standard for a hose size is usually determined by the inside diameter (I.D.), and outside diameter (O.D.). The outside diameter becomes more important when the hose assembly will be installed in a confined space. The overall length of the hose should be spec'd with fittings included.
What is the temperature of the what is being passed through the hose and what is the ambient application temperature?
The selected hose(s) must be rated to withstand the applications minimum and maximum temperatures. The most important aspect dealing with temperatures and the hose selection process is to ensure that at the highest spikes of temperature in the application the hose will not have a catastrophic failure.
What type of machine and/or set up will the hose be used for? Routing? Orientation? Bend Radius Requirements?
A major factor when selecting a hose is to understand how the hose will be used in the application, what type of equipment it will be installed in and what are the environmental factors, to name a few. It is vital to verify and understand all aspects of the application the hose will be utilized in to make certain the hose is rated for the conditions it will be utilized in.
What type of material or media will the hose be subjected to?
Another vital aspect to consider when selecting the proper hose for the application is to check the compatibility with the material that will be conveyed. Check your chemical compatibility chart to ensure that everything from the hose, cover, O-rings and hose fittings are rated favorably for the materials in the assembly.
What is the pressure flowing through the hose assembly?
By determining the application's working pressures, you can then choose the proper pressure rating for the hose. A rule of thumb is the working pressure in an assembly must be equal to or greater than the system pressures. If there are pressure spikes that are greater than the recommended maximum pressure of a hose, those will ensure a shorter hose life.
What types of fittings and thread style are necessary to connect the hose to the equipment?
When determining what type of ends and threads needed on the hose for the application it is important to understand the set-up to install the proper couplings, adapters, fittings and the correct metal for the material that will be conveyed.
What are the hose assembly requirements for testing, packaging, and delivery?
After doing all the specification work for the hoses it is just as important to understand how the hose assemblies should be packaged, tested and delivered per customer, test or certification requirements.
