Save time and money by asking the good questions: powerful educational device (STAMPED).
The mnemonic aid (acronym) to help with selecting the right industrial hose is STAMPED: size, temperature, application, material, pressure, ends, and delivery. In this article, we explore the last five categories (see the previous article for the overview and the first two). We also always have friendly staff standing by to support you in making the right purchase.
How will the hose be manipulated? What environment will the hose be in during regular use and how will it be installed? Will it undergo any flexing, folding, dragging, compressing, oils/chemicals, etc.? Are there requirements such as conductivity or in relation to meeting government or industry regulations? What would happen if the hose fails? Would it entail critical or costly damage to property, personnel, or the environment?
What substance is being conveyed through the industrial hose? If it is chemical, what are the concentrations (%)? In what state will it be transmitted (e.g. wet, dry, steam)? How big are the individual elements/particles? Are they sharp or abrasive?
Will the hose be used for a pressure and/or vacuum application? What is the maximum working pressure? Is the pressure or vacuum constant, or are there peaks? Again, it can be dangerous to operate an industrial hose (or allow it to surge) above its maximum working pressure/vacuum.
What type of end is required to connect the hose? The consideration given to the above questions (application, pressure, size, material, etc.) also have an impact on what type of fitting and clamping should be used. The old adage works well here: the weakest link breaks the chain.
This is really a question of making sure you get your hose on time, with all the necessary testing and certification. Luckily, we have warehouses in three strategic locations across the country to cut down on shipping time. It is also worthwhile to include a bit of time to fully inspect and/or re-test once installed, and periodically over its lifetime, particularly if the hose (and fittings) is used for a critical application.
