Has your blast hose worn out faster than expected?
This can be happening because of a few reasons. There’s one reason that’s more common than the rest, though. Let’s dive deeper!
MEASURING YOUR RUBBER WITH A DIN RATING
Majority of the time, rubber is measured with a DIN rating. The higher the DIN rating, the higher the quality. The rubber gets tested by a machine that has a wheel run across the rubber to see how much of the rubber is removed during the test. The amount of rubber that comes off is then weighed.
There are two blast hose standards. The first standard is DIN rating < 50, which is the higher quality of the two. This basically means less rubber was taken off during the test. The second is DIN rating < 70.
OTHER REASONS YOUR BLAST HOSE IS WEARING OUT
Aggressive abrasive – Blasting with aggressive abrasive or small particles will cause the blast hose to wear out quicker.
Unnecessary bends in hose – Regularly check your hose to make sure there are not any harsh bends.
Leaking air – Make sure air isn’t leaking out around the joints. Also check near the couplings and nozzle.
CHEAP BLAST HOSES AREN’T ALWAYS THE WAY TO GO!
At the end of the day, investing in a higher quality blast host will save you time and money.
