Does anyone know of any industry standard on how often flexible pump hoses should be replaced?  Do they wear out on a regular basis?  Are there any methods used to determine when a hose is worn out?   

When it blows out

Wow.  Interesting.  Thanks.

1. There is no industry standard.

2. Naturally they wear out on a regular basis, always depending on how much concrete you put through them and what the concrete is like (rough stuff, shotcrete with steel fibres etc)

If you're running a line pump, why not check those hoses every winter period in slack times, or even ever 2 or 3 months if you're doing a lot of work. Hang them onto your pump, blind plug the end of the line and go to full power. Clearly you need to run the hoses somewhere secure and safe just in case one of them blows. Any weak spots you'll see because you get bladders blowing up in the rubber or you get water out of the crimpings.

you can usually tell the condition by interior wear. it generally won't blow unless you plug though

excellence reply mister perkins

Check the end it will usually star wearing the metal

With steel belted hose when they wear sometimes the wires are exposed inside the hose. If you ever see any kind of wire inside the hose THROW IT OUT RIGHT THERE AND THEN. If the wire becomes too exposed it can grab the concrete when you least expect it with very serious consequences.

Unless your connecting to pipeline on the ground or static line and need the pressure rating there really is no reason to use a steel belted drop hose.

I find when you pick the hose up and it bends (kinks) real easy or has soft spots, it is probably time to replace!! and like PUMBO said if you can see steel belts THROW IT.

you forgot to Release the air cuff didnt you ;) lol jk

Tallen, had a 4" blow up on me inside a hotel when the hose got kinked, caused $100,000 damage....boss found out afterwards some manufacturers recommend replacement after ten years...most hoses have a stamp on the collar....depends on use too

Use a bit of commen sence.. 10 years for an endhose?? Come on.. Its better to be safe than sorry with this kind of stuff. It can be so much more expensive than just one hose if you wait to long.. Like in that hotel.. 100,000.. Think how many hoses you can buy for that.. 

1-3 years depending on use is nice for an endhose I think. If the wear doesn't kill it the weather (drying out) will.. 

that aircuff squeezing that hose does not help it at all, and 10 years on a end hose ? never heard of that , if we get 2-3 years we are doing good,
