How to check a blast hose for wear.
With constant use, blast hoses get worn. A flimsy, cracked, and hole-filled hose can be potentially dangerous. So, before and after every job, remember to check your hose.
How to perform a hose check.
When evaluating your blast hose, check it visually, and physically squeeze the hose at regular intervals - from the blast pot hose coupling to the nozzle coupling.
- If you find any evidence of splitting, cracks, or holes along the length of the hose, you should replace it in its entirety. However, if the damage is localised to a small section, the area can be cut out and the hose length shortened.
- Worn sections of the hose will feel physically softer. If your hose has lost rigidity in areas, it may indicate internal damage which is grounds for a complete hose replacement.
Don’t be tempted to jerry-rig a dodgy repair!. Using tape to patch a hose damage is highly dangerous.
Best practice maintenance includes:
- Keeping the hose away from chemicals, sharp edges, and any vehicle movement.
- Making gradual bends rather than sharp turns that might increase wear.
- Using a safety cable if the hose runs over structures – to support the weight.
- Closing the metering valve after blasting and blowing air through the hose to get rid of remaining abrasive.
