S.T.A.M.P.E.D. – The Most Important Part of the Hose Selection Process

Kevin Olmstead | April 27th, 2015

The S.T.A.M.P.E.D. acronym is an industry-wide standard that should begin every conversation when replacing an existing hose, or spec’ing in a hose for a new application. The easy to remember acronym stands for Size, Temperature, Application, Material/Media, Pressure, Ends, Delivery.

Size

Size would refer to the i.d. (inside diameter) of the hose, as this is also the industry standard in getting an accurate measurement of a hose. Sometimes the o.d. (outside diameter) might be a critical measurement in confined spaces, which can be just as important, so that is worth noting as well.

Temperature

Temperature is the next issue that should be discussed when recommending a hose. Both the temperature of what’s being conveyed through the hose, as well as the ambient temperature can make a difference in the proper hose selection. It is very important to choose a hose that will handle the highest spikes in temperature that the hose might see.

Application

Application refers to how the hose will be used, and under what conditions. Are there any unusual bends that might affect the life of the hose? What are the conditions under which the hose will be used? Is the hose going to be subjected to internal or external chemicals that will affect its life?

Media

Media specifies what is being conveyed through the hose. Is the hose going to be subjected to abrasives, caustics, or other chemicals? It is imperative to ask about what concentration of a specific chemical will be conveyed through the hose, as this is a major influencer of choosing the correct hose compound to handle that chemical.

Pressure

Pressure is another very important piece of information that we need in order to recommend the proper hose. Most hose is made to a 3:1 or 4:1 burst to working pressure safety factor. For example, a 4:1 hose that has a working pressure of 2000 psi (pounds per square inch), would have a burst pressure of 8000 psi…although, this doesn’t mean you should go over the 2000 psi limit for which the manufacturer has rated it. Bottom line, the hose should be able to handle the highest pressure that the system will see. Using a hose that isn’t rated high enough can cause serious injury, and even death.

Ends

E is for ends. What fittings will go on the end of the hose? What style thread is necessary to connect the hose to your equipment. In the case of elbows, what is the correct orientation of the 45 degree or 90 degree fittings to face? Am I using the correct metal for what I’m conveying ie: aluminum, stainless, brass etc.

Delivery

Delivery is for packaging, testing, and delivery requirements. Does the hose need to be pressure tested? Is there a specific packaging need to ensure the hose assembly arrives as it left the distributor? How quickly do you need your hose assembly?

The S.T.A.M.P.E.D. system of hose requirements is an absolutely critical list when it comes to recommending the correct hose for the correct application. I will be glad to help you with your selection of hose, to achieve the maximum life out of your assembly.
