When on the hunt for the right commercial hose, it’s critical to keep certain considerations in mind. Hose type, length, diameter, minimum bend radius, material, flexibility, and expected lifespan are all important things to keep in mind.
However, when it comes to PVC hoses with helix tubing, there’s another thing you must look out for: it must have a flow directional arrow on it a requirement of ASME/ANSI A13.
What Are Flow Directional Arrows?
Flow directional arrows are arrows placed on PVC hoses with a spiral-like inner tube (helix) that help indicate the direction in which contents contained within the hose are designed to move. These small visual symbols may be overlooked by those who aren’t familiar with them. Nevertheless, they play an important role as they act as a little reminder or instruction for those utilizing the associated hose.
Why Flow Directional Arrows Are Important
These arrows are vital for helix-styled PVC hoses because if the user operates the hose the opposite direction as it’s intended, the contents within will travel through against the hose’s lip. In turn, the hose will experience greater wear over the years – and sooner, too.
The goal with any commercial hose should be to take the best care of it as possible. The extra caution will not only save you money from having to keep buying new hose supply, but it can reduce your chances of experiencing a dangerous disaster if your hose fails during operation. That said, paying attention to the flow directional markers on your hose – if it contains one – is an absolute must.
